Plot X-Y graph with multiple y values on same x axis

Dear all,
I have written some vi on a small part of my application. Basically, every 20 sec, I will acquire a set of readings (array) consisting of 10 data points known as T1. So at every timestamp, there should be 10 datapoints plotted on the same timestamp. Then 10 sec later, another timestamp with again 10 datapoints. I wanted the data to be plotted and updated every 20 sec and continue till I stop the program. At the end, I hope to see 10 horizontal lines.
I face some problems now and hope someone can help me on this? The problems are how do I plot the 10 datapoints at every interval of 20 sec. How do I also keep on updating the data? I know I need to build arrays but I am not sure how to do it.
Someone who knows please kindly help me on this as I have been trying but to no avail.
Solved!

Dear All,
I have tried the program again. But there is still some problems.
How do i create the time interval of plotting the 10 datapoints every 20 sec interval. Meaning how can i plot 10 datapoints at one timestamp and another 10 datapoints another 20 sec later? Right now it seems that if i introduce a delay of 2 sec, the graph will be plotted 2x10= 20 sec later. However i want the scan rate to be 20 sec. If i set the delay at 20sec, then i will have to wait for 20x10=200 sec right? Is there a way to make it plot every 20 sec interval interval but not 2 sec scanning rate?
Right now, the x-y graph will refresh itself after 10 loops. However i also want to keep the previous datapoints (plots) in the previous timestamps also and it should be continuing since i started the program . How do i modify the program as i think i need to use build array function and shift register somewhere.
Can anyone assist me on that? Thanks!
Kudos! Thanks!

Convert a scatter graph with multiple data series into individual graphs

I am trying to convert a scatter graph with multiple data series into individual graphs, with the series having the same formatting as in the graph when all series are together.
Normally, if I delete any series, the color scheme for all the other series vanishes. I can then waste more time in having to re-adjust the color and shape of the series, but this is tedious. This, I do not want. Is there an automated way to do this?
Ideally, of course, all series would appear in little subsections in the space of the former one graph, all with individual axes, but I can't have all, so I'll settle with having several individual new graphs, each with just one series, and with the original
formatting.
Thx.

How about creating a copy of the chart, and then setting all series except one to be transparent (no line, no marker)? Repeat for each series.

Reeal-time 3D graph with multiple plots

Hello,
I realise this is a very complicated question and I would appreciate any healp anyone could give. I am trying to:
1- draw a 3D graph with three plots (plots are from coordinates read from XL)
2- do it in real time, so that only one point from each plot shows at a time (the previous points disappear)
Can anyone help me out? I looked at Sarah's advice and I got as far as the program that I have attached. I have also attached an XL sheet with random values (actually I didn't have any luck attaching two files).
I would appreciate any response!
Thank-you,

Could you look at this new and improved (yet not perfect program) and help me out?
Issues:
Why do the axis all change and why aren't the points drawn all at once? ALso, is it possible to retain in memory and plot more than one point from each plot at once?
The axis are changing because you didn't ask for constant scales. Just right-click on the 3D graph indicator and go to CWGraph3D/Properties... There a pop-up window will give you access to a number of settings. Explore. You will find how to allow the user to pan/zoom/rotate the graph, and to disable autoscaling...
The points are not drawn all at once because you pass them one at a time!!! To plot several points at once, you have to build an array with the proper number of points (initialise first) then you can rotate the array after plotting, and replace the first point at the next iteration.

How do I graph multiple bit values on one time axis?

I want to graph multiple bit values, all of which will change back and forth from 0 to 1, on the same time axis, but I don't want any visual overlap between the different bit value traces. Now I could do this by graphing bit one as either 0 or 1, bit 2 as 2 or 3, bit 3 as 4 or 5, etc., but I would really rather have multiple Y axes showing 0 to 1, stacked vertically on the same time (X) axis.
You could visualize this as multiple pens on a strip chart continuously recording different values. Each pen has its own vertical area in which it writes, but all pens could be writing data from the same numerical range.
Hmmm... I think my description might be roughly as clear as mud, but if anyone out there can figure out what I am asking and has potential solutions, please let me know.
Thanks!

Thanks. I will look at that VI, but I think I have already seen it. My problem is that I have CAN data coming in for an hour or so, but the time interval between receiving specific CAN arbitration IDs varies, so I want to plot the X axis against specific, varying time values, not a standard dT. I'm not sure I can do this on a digital graph, but I haven't given up hope yet.
BTW, I am receiving 8-byte CAN packages. Some of the bytes represent actual values, but I need to break others up into individual bit values to see error and status flag settings. Once I break the bytes into bits, I convert from analog values to digital values.

Creating a simple graph with time and values?

I think I'm probably just plain stupid that I can't seem to get this done, but I've been trying now for two hours and tryed the help section so some one please help!
I have a table with quite a lot of columns.
First column is the years, the other column are prices values for different regions.
Why can't I pick two regions and plot them against the years????
I can pick two regions and plot them, but then I don't get the years underneath.
When I try to add the years, it also ends up as a value on the y-axis, while I want those as the x-axis.
This can't be difficult... even in Excel it took me five minutes to get it, so why not here??????

Bar Graph with multiple series

I am trying to created some graphs in 10g reports. I want a graph that has 2 bars per group. On the layout tab I have column A and Column B on the bars line and Column C on the groups line. When I run the report Columns A and B show up as 1 bar on the graph. Where do you specify the values for series 1 and series 2?

Hi,
When you create a bar chart using a "group by" attribute, the resulting groups are displayed as stacked bars or as dual Y bars (shows the groups side by side). The button in the chart's toolbar (with stacked bar chart icon) is used to change this presentation. You can display the data as it is, without aggregation, by using the line or scatter charts. The line/scatter graphs should allow you to display multiple Y values (series), but there appears to be a bug that causes a single line to be displayed instead. Multiple series bar charts and label renaming are not available in the current release.
Thanks,

How to draw xy graph with multiple y axis input?

Hi,
I have problem in xy graph, the xy graph only can show 1 signal from the y axis input ( As you can see in the attachment )
Is it possible to draw xy graph with 2 Y input? Or maybe there are another type of graph that possible to do this?
Note: the x axis should be from an input too ( not versus time / sample ).
All answer and advice are welcomed.

Are you asking for a second Y scale on the graph?
If so, right click on the existing scale, select "Duplicate Scale". This will create a second scale. You can then (if you wish), right click on the new scale a select "Swap Sides" to put it on the other side of the graph.
Are you asking about adding a second plot?
If so then you need to bundle your arrays of X and Y points into clusters and build those into an array:
The X-axis is always from an input on the XY Graph. You just need to change the axis title. Easiest way to do this is to double click on the axis title and type the new name.

How to avoid SYSTEM_NO_TASK_STORAGE with multiple single values variable

Hi experts,
I am trying to do a distribution with reference data standart SAP function.
Fields to be changed:
ZPDHIER2 (Economic Group II)
ZPDHIER3 (Economic Group III)
ZPDCLIENT (Client)
Fields for condition:
KEY FIGURE NAME
Fields for reference:
KEY FIGURE NAME
ZPDSTATUS (Status)
FISCPER3 (Fiscal Period)
The parameters group is like:
Fields for condition:
Key figure: ZM_070 (one of the key figures)
Fields for reference:
Key figure: ZMONT_TN
FISCPER3: 001
Status: DE
- "Only distribute not assigned" is checked
I do not want the data to be distributed by any ZPDHIER2, ZPDHIER3 and ZPDCLIENT so I have restricted these characteristics in the planning level by some variables. These variables are user exit type and return multiple single values.
The issue regarding this message is that when I execute this function, depending on the size of the data brought by ZPDCLIENT user exit variable, this dump might or might not occur. As for the testing I've done, i realize that if the number of clients exceed 500, dump will occur.
This multiple single values variable (or any other solution) must be prepared for 3900 clients, and this number is expected to increase.
Anyone have faced same problem?
Hope you can provide me some help regarding this issue.
Tanks in advance,
André Oliveira

Hi Wadih saad,
I think the memory is not suffcient to hold the load. Check your swap space and memory during the client export and also check whether there is sufficient space in the hard disk to hold the export files.
You must have calculated the client size by using the test run. This size must be available as free space in hard disk to do the export.
Make the available space and do the export it will work.

Security Attributes with Multiple/NULL values

I have a couple of situations where I can't seem to get the authorization component working as I need it to work for a database source.
1) In the first case, I have two attributes set for "grant security attributes" in the data source, one of which has a single attribute value, and the other which has multiple values, e.g.
I want to set "grant security attributes" to something like "client_id role_id" where for my dataset, client_id will always be a single numeric value, but I might have multiple role_ids that can view this record. How do I specify in my data source query those multiple attribute values? I tried separating them with spaces, e.g.
SELECT ...
'A B' role_id
FROM
where "A" and "B" represent unique values (looking to match A OR B). I also tried delimiting them with commas, but neither spaces nor commas seems to work consistently.
On the authorization end, using oracle.search.plugin.security.auth.db.DBAuthManager as the authorization plug-in, I have the authorization query set as
SELECT client_id, security_lvl as role_id from test_user_id where user_id = ?
Each user may have more than one role, so in the above query, security_lvl could be something like "B C"; I'm assuming from the documentation that the delimiter for attribute values in this case should be a space.
The crawler logs make it appear that everything is getting indexed, so I suspect the issue is on the authorization front.
2) In the second case, one of my security attributes for the data source may be NULL, meaning that there's no particular authorization restriction on a particular record, so to use the same example as in #1,
role_id might be NULL for some records, in which case, I want those records returned in the search if the client_id matches, but I can't get the records with the NULL role_id to be returned at all. Again, the crawler logs indicate that everything is being indexed, and I'm not sure if there's a log where I can further troubleshooting authorization issues.
Any guidance would be appreciated.
Thanks

1) The security attributes are OR'd together so if the user has any ONE of the attributes (either client ID or role ID), the document can be seen by the user. What I would try is to create a view to call rather than directly against the table. The view can then leverage a PL/SQL function and encapsulate the logic behind the security tokens to return.
So the view would look like this...
CREATE OR REPLACE VIEW USER_SECURITY_V AS
SELECT
USER_T.ID,
MY_SECURITY_FUNCTION(USER_T.ID) AS AUTH_ID
FROM
USER_T
The PL/SQL function would look something like this...
CREATE OR REPLACE FUNCTION MY_SECURITY_FUNCTION(USER_ID NUMBER) RETURN VARCHAR2 IS
-- Do whatever you need to do to build a single space-deliminted list of tokens for both Client and Role ID "CLIENTID4 ROLEID5 ROLEID9" then return
END;
The data source authorization query then would look like this...
SELECT AUTH_ID FROM USER_SECURITY_V A WHERE A.ID = ?
Using a PL/SQL Function to control the tokens gives you the flexibility of modifying security without having to touch the data source directly
2) I don't quite follow. If any ONE of the tokens match, the document is returned. If the role ID is null, you might try stamping each document a "master" security token indicating it's open to everyone such as "ALL". Then in the PL/SQL Function, return "ALL" in front of the actual values.
The crawler logs will only tell you what is indexed at crawl time, not how searching is actually working. Try checking the server logs. These should be under something like oracle/ses/seshome/search/base_domain/servers/AdminServer/logs
Hope this helps!

CreateInsert and LOV with multiple return values

HI. I am on Build JDEVADF_11.1.2.3.0_GENERIC_120914.0223.6276.1
I have a View Object which is based on Entity Object.
View Object has customer_name and customer_id attributes.
customer_name attribute has LOV (input field with LOV) based on some other View Object (which of caurse holds customer name and customer id data)
I defined that when LOV return the chosen values it will populate customer_name with "Customer Name" value and customer_id with "Customer Id" value
All atributes are updatable
I droped my View Object on the page and also "CreateInsert" buton. When I click on "CreateInsert" button, I can see new row added as expected, customer_name field has LOV. I can choose from LOV and can see customers and customer_id data. But when I click OK in the LOV pop-up only customer_name attribute is populated!
I do see that customer_id is returned from LOV (I implemented ReturnPopupEvent listener), but still the customer id remains empty.
I though maybe I need to add LOV as auto submit = true and set LOV to be a partial trigger for customer_id. But still - it didn't help
However, if I run Application Module tester, I do get what I want. I can create new row and when I change customer name , both customer name and customer id fields are populated
Please advice

Hi Michael,
On Lov VO, make sure you have at least one or combination of attributes as Key attribute. and re test.

Copy using Variables with multiple single values in BEX

Hi,
I have a requirement wherein on executing the planning function, the system should take the FROM and TO values of 0FISCPER and copy the data accordingly.
Source variable is 'Single Value'.
Target variable is 'Multiple Single Value'.
I tried to give the Command Range as below:
$A$30:$C$31.
The button sequence is as below:
VAR_NAME_1      0         ZFISCPER
VAR_VALUE_1     0
VAR_NAME_2      1         ZFISCPER_M
VAR_VALUE_2     1
In the Analyzer, I entered the values as
In A30, VAR_NAME_1     0     =C20
In A31, VAR_NAME_2     1     =C21:C24
The values that I entered are as below:
C20 =   2007001 - Source value
C21 =   2007002 - Target values
C22 =   2007003
C23 =   2007004
C24 =   2007005.
The problem that Im facing is the system is unable to identify the multiple values that I enter for Target Fiscper and it displays as :#VALUE!
How to enter multiple single values and reference them accordingly?
Rgds,
Shyam

Hi,
I have tried to enter multiple single values as below:

VAR_VALUE_2     1     010
VAR_VALUE_3     1     080
VAR_VALUE_4     1     099
When I tried to execute the planning function, the system copies the data from version 000 to ALL versions irrespective of values entered above.ie:

2
3
10
80
99
100

Lightroom CC issues with multiple export at the same time

Back before Lightroom updated to the CC version, I was able to use export presets to send 4 different versions of the photos I'm working on at the same time (A Full Size for client at certain size, full size for myself, web-sized with watermark and a thumbnail). Since updating to the CC version, I'm only able to start the export process on two of these versions before the system simply becomes crippled and I cannot even navigate through Lightroom without it chugging along.
For reference, I'm running a 2014 rMBP with 16GB of RAM, LR is the only app open at the time and it's showing that I have roughly 6GB of RAM free when attempting this export.
TL;DR: LR5 worked wiht multiple exports at the same time, but LRCC now chugs after 2 exports are started

Re: "Selecting video in Messages, now starts Face time for video. Face time is one to one only."
Apple "Messages" supports two different types of video conferencing. It's become more than a little confusing. If you (or the person on the other end) ONLY have accounts set up for Apple's "iMessage" service (associated with your Apple ID and "iCloud") you may see the video symbol, but when you click on it you will be connected via FaceTime which is limited a 1-to-1 video conference.
However, if you have set up an AIM account in Messages (you may already have an AIM account ID if you once used iChat for video, audio and screensharing) and the person at the other end also has an AIM account you will be connected via AIM and will be able to do screen sharing and multi-person video conferences just like the old iChat, i.e. you'll have iChat Theater features, up to 4-way conferencing, etc.
It can get very confusing if, for example, you've signed up for AIM using a .me or .cloud email address. But once you have it set up and learn to recognise the way Messages switches between AIM and iMessage all the old iChat features work just fine in Messages.

Timesten replication with multiple interfaces sharing the same hostname

Hi,
we have in our environment two Sun T2000 nodes, running SunOS 5.10 and hosting a TT server currently in Release 7.0.5.9.0, replicated between each other.
I would like to have some more information on the behavior of the replication w.r.t. network reliability when using two interfaces associated to the same hostname, the one used to define the replication element.
To make an example we have our nodes sharing this common /etc/hosts elements:
151.98.227.5 TBMAS10df2 TBMAS10df2-10 TBMAS10df2-ttrep
151.98.226.5 TBMAS10df2 TBMAS10df2-01 TBMAS10df2-ttrep
151.98.227.4 TBMAS9df1 TBMAS9df1-10 TBMAS9df1-ttrep
151.98.226.4 TBMAS9df1 TBMAS9df1-01 TBMAS9df1-ttrep
with the following element defined for replication:
ALTER REPLICATION REPLSCHEME
ADD ELEMENT HDF_GNP_CDPN_1 TABLE HDF_GNP_CDPN
CHECK CONFLICTS BY ROW TIMESTAMP
COLUMN ConflictResTimeStamp
REPORT TO '/sn/sps/HDF620/datamodel/tt41dataConflict.rpt'
MASTER tt41data ON "TBMAS9df1-ttrep"
SUBSCRIBER tt41data ON "TBMAS10df2-ttrep"
RETURN RECEIPT BY REQUEST
ADD ELEMENT HDF_GNP_CDPN_2 TABLE HDF_GNP_CDPN
CHECK CONFLICTS BY ROW TIMESTAMP
COLUMN ConflictResTimeStamp
REPORT TO '/sn/sps/HDF620/datamodel/tt41dataConflict.rpt'

SUBSCRIBER tt41data ON "TBMAS9df1-ttrep"

On this subject moving from 6.0.x to 7.0.x there has been some changes I would like to better understand.
6.0.x reported in the documentation for Unix systems:
If a host contains multiple network interfaces (with different IP addresses),
TimesTen replication tries to connect to the IP addresses in the same order as
returned by the gethostbyname call. It will try to connect using the first address;
if a connection cannot be established, it tries the remaining addresses in order
until a connection is established.
Now On Solaris I don't know how to let gethostbyname return more than one interface (the documention notes at this point:
If you have multiple network interface cards (NICs), be sure that “multi
on” is specified in the /etc/host.conf file. Otherwise, gethostbyname will not
return multiple addresses).
But I understand this could be valid for Linux based systems not for Solaris.
Now if I properly understand the above, how was the 6.0.x able to realize the first interface in the list (using the same -ttrep hostname) was down and use the other, if gethostbyname was reporting only a single entry ?
Once upgraded to 7.0.x we realized the ADD ROUTE option was added to teach TT how to use different interfaces associated to the same hostname. In our environment we did not include this clause, but still the replication was working fine regardless of which interface we were bringing down.
My both questions in the end lead to the same doubt on which is the algorithm used by TT to reach the replicated node w.r.t. entries in the /etc/hosts.
Looking at the nodes I can see that by default both routes are being used:
TBMAS10df2:/-# netstat -an|grep "151.98.227."
151.98.225.104.45312 151.98.227.4.14000 1049792 0 1049800 0 ESTABLISHED

151.98.226.5.44949 151.98.226.4.14005 1049792 0 1049800 0 ESTABLISHED
Tried to trace with ttTraceMon but once I brought down one of the interfaces did not see any reaction on either node, if you have some info it would be really appreciated !
Cheers,
Mike

Hi Chris,
Thanks for the reply, I have few more queries on this.
1.Using the ROUTE CLAUSE we can use multiple IPs using priority level set, so that if highest priority level set in thr ROUTE clause for the IP is not active it will fall back to the next level priority 2 set IP. But cant we use ROUTE clause to use the multiple route IPs for replication simultaneously?
2. can we execute multiple schema for the same DSN and replication scheme but with different replication route IPs?
for example:
At present on my system, I have a replication scheme running for a specific DSN with stand alone Master-Subscriber mechanism, with a specific route IP through VLAN-xxx for replication.
Now I want to create and start another replication scheme for the same DSN and replication mechanism with a different VLAN-yyy route IP to be used for replication in parallel to the existing replication scheme. without making any changes to the pre-existing replication scheme.
for the above scenarios, will there be any specific changes respective to the different replication schema mechanism ie., Active Standby and Standalone Master Subscriber mechanism etc.,
If so what are the steps. like how we need to change the existing schema?
Thanks In advance.

I'm having problems in a GOOP application with multiple instances of the same object running simultaneously.

I?ve written an application to control a system with multiple lamps. Each lamp in the system has its own power supply. Each lamp object contains a reference to its power supply. The application contains an array with the references to all the lamps in the system. Each lamp is in charge of monitoring itself and setting its power supply?s voltage according to the applications commands, therefore each lamp needs that its ?run me? method will run as long as the application is running i.e. the run method has to be reentrant. Because there are multiple lamps and because the ?run me? methods for each lamp run simultaneously, to over come this problem each lamp has a met
hod ?run? that calls ?run me? with ?RUN VI? invoke node with the ?Wait until done? set to false. When I run the application, it seems to work but if I check the AO there is no change in the output, and the lamps seem to be reading their input from the same channel. I can?t seem to find the problem, I think that the fact that the method is reentrant causes some sort of mix-up in the separate object references. Also because the method is reentrant I can?t debug it (with one lamp it seems to work ok). Does anyone have any idea what could be causing this problem.
P.S I'm having problems attaching my sample program to this message. You can contact me at [email protected] to recive the sample program I wrote.

Jean, Thanks for your answer, I've tried checking the invoke node that calls the "Run VI" method but it doesnt return an error any of the times its called even that the Vi that it called is still running. I also tried your solution of changing the object's "Run" method to a template but that doesnt work either. I can't seem to post the sample progam that demonstrates the problem, is it possible to send it to you by email, contact me at [email protected]
