Working with dynamic scales in waveform graph - display problem

Hello
I want to use the same waveform graph in the frontpanel for different measurements. These measurements contains 1 to 8 curves, some of them I need to autoscale and others I want to use fixed scales. I wrote a method containing these functions and the functional behaviour is how I expected. But when it runs several times, LabView cannot correctly manage the graph display. Some scales are behind the graph or two scales are at the same position.
Perhaps you have a look at my example VI (LV 7.1), I generate a random Waveform and want to display a random number of curves and some of them in fixed, and some in autorange. The more I run the VI, the more the waveform graph display gets wrong. Does anybody know a solution?
Thank you very much for answering!

hi there
Ben, thanks for the link. Christian's suggestion is right and describes a similar problem.
I solved the problem now on an other way. Each time before I change the visability of the scales I reset all settings to the default (startup) values by property nodes (YScale.Maximum, YScale.Minimum, All Visible...). Then I make the scales which I don't need unvisible, link the graphs to the prefered scales and set the Min/Max or autoscale.
Important: I got 4 scales on each side. When I want to use eg 2 scales on the left, I need to make visible scale number 1 and 2. Scales 3 and 4 can then be set to unvisible (in other words in an incrementing order).
Makeing scales visible and unvisible is a little bit nervous on the screen. So, during that process I bring a picture of the last waveform on the top of my screen and change to the graph view when all settings are done.
Now I got a really great waveform viewer with the possibility, scaling some graphs by autoscale, others by fixed scales, using up to 8 scales selectable on the left/right side, user definied colors, names and units.
Thank you all for taking part of my problem.

Encountering error while working with Dynamic Regions.

Hi All,
I am a beginner in ADF and on a quest to learn ADF. Sometimes I am struggling in the process. Now, when I am working with Dynamic Regions, encountered problem below
Step 1 : Created a simple department TaskFlow with Department Form
Step 2: Created a Simple employee TaskFlow with Employee Details
Step 3: Created a Main page with oracle 2 column layout
Step 4 : Dragged and dropped department TaskFlow on to main page second facet as Dyanmic region . Created a bean as RegionBean
Step 5 : Dragged and dropped department TaskFlow as Command Link on the first facet
Step 6 : Dragged and dropped employee TaskFlow as Command Link on the first facet
The page runs and shows department information when it renders. But when I click on employees command link, at first it shows employees table with no data and says "ACCESS DENIED ". Then if I click on either department or employee command link, it errors out with below info

Making Worksheet logic work with Dynamically expanding report

Hello,
Sorry if its basic, but I am trying to understand how can I make worksheet logic work with dynamically expanding reports? Because if the expansion parameters change, it stops producing correct values for me. Please advise.
Thanks.

Hi Zack,
Now I understood your problem.
Actually, when the expansion changes, it deletes the columns, and then shifts the subsequent columns with the appropriate expansion. So, if you have the formula somewhere in between, you will lose it. If you put it in the beginning, then it will be copied to all the cells. You need to put it at the end. But, you are saying this is viable for your scenario.
My suggestion would be you can try to break the single expansion into multiple expansions using the pipe (|) character, and place the formula in one of them.
Hope this helps.

Photoshop Elements 12 no longer see's my scanner. So I cannot scan my pictures, help. Windows 8.1 with HP Officejet 6500A Plus printer. Scanner works with other programs in my PC. Problem is PS12

So I cannot scan my pictures, help. Windows 8.1 with HP Officejet 6500A Plus printer. Scanner works with other programs in my PC. Problem is PS12

I bought the Officejet 6500A Plus about one month and have experienced the very same problem. I tried to remedy this problem following suggestions in a number of different posts (static IP, router, firewalls etc), all to no avail. Last week I called support. The support I received by the tech over several hours and different days for a week was very good. However none of his suggestions corrected the connection issue. After today's recommended fix failed, he advised HP is aware of this issue with the 6500 and other affected printers. He claimed HP was working on a firmware upgrade. He did not know when the update would be provided. The tech also claimed HP acknowledged this problem in a written announcement. He agreed to email the announcement to me. I haven't received it. This has been the only problem I've had with the 6500

Can I make waveform graph display more than the currently read samples?

I have DAQ reading in 17 channels at a rate of 500 samples/second and then writing to a TDMS file, to some guages, and to a waveform graph. I would like for the waveform graph to display more than the samples that are currently being read, I'd like for it to display the last ten seconds worth of samples. How can I accomplish this?
I've attached a picture of the relevant section of my VI. If you need anymore information about the VI just let me know.
Thanks!
Solved!

If you want to use graph only then try with the vi attached in which shift regs are used to store the previous data... I think you can use this and optimise further accordingly..

Waveform graph displayed vertically on front panel

Hello everybody
I would like to know if it is possible to display waveform graphs vertically on front panel and if enventually could someone tell me how to do it.
Thanks vey much for help.

You'll have to use an XY graph, and do some programming. You could use the attached vi that simulates a vertical chart as source of inspiration.

hi kathy-
thanks. i'm using jaxrpc 1.1.2 version.
i can get everything to compile fine but i get errors when i try to send it.

Flash chart with dynamic sql query does not display

Hi,
In my schema SIVOA I have a lot of tables declared like this :
CREATE TABLE "SIVOA"."EVV_xxxx"
   (     "CLEF_VAR" NUMBER(4,0),
     "DATE1" DATE,
     "VALEUR" NUMBER(16,8) Only the last part of the name changes "xxxx". For example E009, E019, etc....
I am making a chart page with report and want the user to select a name of a table and I will display using dynamic sql query, the table report and chart.
P184_ENAME is a select list returning the last part of the name of the table, fro example 'E009', 'E019', etc.
P8_CLEF_VAR is an item containing a value. This value is a key retrieved like this :SELECT CLEF_VAR
FROM SIVOA.SITE_ECHELLE
WHERE SITE = :P184_ENAMEI built a classic report using a sql dynamic function :DECLARE
x VARCHAR2 (4000);
BEGIN
x := 'SELECT NULL, DATE1, VALEUR FROM SIVOA.EVV_'
|| UPPER(:p184_ename)
|| ' WHERE CLEF_VAR = :p8_clef_var' ;
RETURN (x);
END;:p8_clef_var is an itme containing the value '4544'.
This works perfectly fine !
When I use this sql fucytion into a flash chart it does not work. I get this message "No data found".
I do not understand why a the report get a result and not the chart !
But if i hard-code the number of the CLEF_VAR instead of fetching it from :p8_clef_var I get a nice chart ! Go figure !DECLARE
x VARCHAR2 (4000);
BEGIN
x := 'SELECT NULL, DATE1, VALEUR FROM SIVOA.EVV_'
|| UPPER(:p184_ename)
|| ' WHERE CLEF_VAR = 4544 ' ;
RETURN (x);
I cannot stay with the key (CLEF_VAR) hard-coded unformtunately !
My question is how to get the chart displaying properly ??
Thank you for your kind answers.
Christian

Alex,
Using your request, with the classic report I get results (data), but I get the same message with the Flash chart : "No data found" ! I don't know how to investigate this. i tried many things but nothing works.
Christian
PS I tried this :
DECLARE
   X   VARCHAR2 (4000);
BEGIN
x := 'SELECT NULL, DATE1, ROUND(VALEUR,2) FROM SIVOA.EVV_'
      || UPPER (:p184_ename) ||
      ' WHERE CLEF_VAR = '
      || :p8_clef_var ||
      ' AND DATE1 BETWEEN TO_DATE ('''
||:P8_DATE_DEBUT||''', ''DD/MM/YYYY HH24:MI'') AND TO_DATE ('''
||:P8_DATE_FIN||''', ''DD/MM/YYYY HH24:MI'')'
RETURN (X);
END; But it does not work either. I could find that the SLQ syntax generated is good becaus I put it into an item which display the return done by the pls/sql.
What is sttange also with the classic report is that if I do click on next or previous to see another rows, I get the message "No data found". If I try to export the report I get an excel file with "No data fouid".
Does anybody already tried my "need" here ? i find strange thant I should not be the firs one trying to get a report an tables which name would be "dynamic".
Tahnk you.

Stabilizing not working with Dynamic Link

So, here's the steps:
1) Right click clip in premiere
2) Select 'Replace with after effects comp...'
3) In AE i click 'Stabilize Motion'
4) Select motion source 'cu_1.mpeg' the only video track
5) Check 'Position' and 'Rotation'
6) Setup my two tracking points
7) Click 'Analyze Forward' button
8) When analyzing is done i click 'Apply'
At this point the clip is stabilized.
9) Click 'Save' and return to premiere
This is where the problem is. Premiere sees the linked AE comp but doesn't do all the stabilizing. From what i can tell it's doing the anchor point but ignoring the rotation in the AE comp. I think this because i do see the edge of the frame moving around like it's doing some stabilization.
The clip is fine if I pre-render the AE comp.
Any ideas?
Thanks,

It's not enough to just type : embedFonts = true.. You have
to link also your fonts to be included in the produced flash - but
be careful. It will increase enough your swf 's file size,
depending the sets of fonts you enter!
The only secure way I have found to do it, using and other
languages characters, is to create a movieclip inside the first
frame of my file, containing dynamic texts with all types fonts
that I am using in my application (i.e. Myriad Pro, Myriad Pro
Bold, Myriad Pro Italic.. etc). I type on those texts just a dot,
and I embed them via Flash CS3 enviroment my fonts. Then I make the
movieclip Invisible.
If you want an example check this one:
http://www.sp7.gr/adobe_forum_data/04_EmbedFonts.zip
Due to embed fonts, the size of swf is ~180KB, although it
displays just a fading text....!

Working with dynamic documents?

Hi - my company is evaluating FLEX for a major new project. We are very impressed so far but are struggling to find a component that will allow us to create a custom report designer / word processor. So far all we seem to come across is buzzword which doesn't appear suitable.
Bascially our clients need to be able to layout a Word style report with tables etc. They then need to be able to map a table cell to a database column. Our software can then dynamically read and write data from a database to the report cells. As our solution is part of a workflow system we also need to be able to enable and disable cells programatically.
A PDF based solution would be ideal.
Hope all this makes sense!
Can anyone recommend a solution.
Thanks in advance
James

I think you're gonna need to build the whole word-like UI, and once
the report is created use AlivePDF to convert it to PDF.
Sincerely,
Michael

Working with dynamic internal tables

Hi,
I've created dynamic internal table and then assigned it to field symbol structure.
This is part of the code.
wa_tab = cl_abap_structdescr=>create( comp_tab ).
i_tab   = cl_abap_tabledescr=>create( wa_tab ).
create data i_table type handle i_tab.
assign i_table->* to <f_tab1>.
As a second step I am populationg that structure <f_tab1> with data using dynamic select:
select (sel_list) from (p_table)
        into table <f_tab1>
        up to p_row rows.
So far so good but I need to copy the data from <f_tab1> into internal table with the same structure and to use that internal table on a later stage as a driver table in select...for all entries.
How can I doo that ?
Thanks,
Stefan

Can I regulate my x-/y-scale on Waveform Graph?

In my program I indicate several signals successively with different frequences. I managed it with a case-structure. Can I give the WaveformGraph scales, automatically the associated attitude.
I won't set the scale always manual.

You can use the Y and X scale range property in a property node to set these properties programmatically.
Take a look at the following screenshot.
