Start timestamp - dynamic signal - waweform chart

Hi,
I have an issue with the start timestamp of an dynamic signal. I'm simulating a sine with the express signal generation. The thing is I can't reset it start timestamp (set it to NOW). The only way I found to do it is to stop my app... and then when I start the app again, the start timestamp resets to present time.
Why does this bother me? I'm plotting this signal on a waweform chart and I want to be able to reset to 0 (I mean, t0 = now) the ''plotting'' of this signal without having to stop the application. I can't beleive there is no way yo acheive this.
Anyone knows?
Thank you
Eric

Hi
Thx for reply, but it does not work... I had already tried to set current time to t0 through the ''build waveform'' and even the ''set dynamic signal attribute express'' VI.It only resets when I stop my app and restart it.
Here what I want to acheive:
I have an application running. On my mean screen, let say I click a buttom to perform a ''get signal'' process and show it on a chart. Once the process is over, bring me back to the main screen.
First time it works well as t0 is at 0 (now, current time). Once I come back to the main screen, I want to perform another one... but can't get my &?$%? signal t0 to ''now'', so my chart do not start at 0, it starts where it was at the end of the first process. I can't beleive it is so hard to do something should be so simple...

Signal flow chart for using DIO on 5640R

Hi,
There are a bunch of good templates to get me started with analog I/O but not for digital I/O. My project needs the host to send out a value through digital lines @10MHz. Now I have a few basic questions regarding the standard procedures to work with DIO?
1. what are the essential items in the signal flow chart on host? Open session->configuration->write->initialization->close session?
2. What are the differences of opening a session using FPGA VI Reference.vi and 5640 init Generation Session.vi? They are not interchangable.
3. Do I have to use a FIFO to transfer data between FPGA and host in this case?
At last, I highly recommend ni group to create a working template for DIO. If easy modification to analog I/O template can work for DIO, please show to how, that'll be great.
Thank you.
Dan

Hi Dan,
The basic flow of programming on the Host for digital output would be similar to:
Open FPGA Reference >> Configuration (as needed) >> Write to FPGA >> Close session
You could use a FIFO to pass data between the host and the FPGA or you could just pass data via controls and indicators. I have included an example project which passes data from the host to a control on the FPGA VI. If you are transferring the data as a 32-bit unsigned integer then you will need to manually format and control the way it is output from the FPGA VI. There is not a pre-made function to do that.
As for testing, you can manually probe the pins on a connector with a DMM. Here is the pinout for the AUX connector.

Thanks
Manish

Hello,
Lots of different ways to do this, I blogged about one way (using a Pipelined function) here -
http://jes.blogs.shellprompt.net/2006/05/25/generic-charting-in-application-express/
Other options include using a PL/SQL function returning the string to use as the dynamic query etc.
Hope this helps,
John.

CONNECT BY PRIOR T.ITEM_NO = T.ITEM_NO_SCO AND PRIOR T.ITEM_TYPE = T.ITEM_TYPE_SCO;
Then run the below query:
select * from test_v where item_no_sco = '00245905'
the output is got within a second. but the real scenario is that both table icont and isct have millions of rows. In that case even this small query of the view takes 10minutes as there a FULL TABLE JOIN.
How do I give the START WITH in the view to make it faster i.e.
even with millions of rows the output of this comes in seconds:
SELECT T.ITEM_NO, T.ITEM_TYPE, CONNECT_BY_ROOT T.ITEM_NO_SCO,T.ITEM_TYPE_SCO
FROM
SELECT NVL(C.ITEM_NO_CHILD, I.ITEM_NO) ITEM_NO, NVL(C.ITEM_TYPE_CHILD, I.ITEM_TYPE) ITEM_TYPE, I.ITEM_TYPE_SCO, I.ITEM_NO_SCO
FROM isct I,
icont C
WHERE I.ITEM_NO = C.ITEM_NO(+)
AND I.ITEM_TYPE = C.ITEM_TYPE(+)
) T
START WITH T.ITEM_NO_SCO = '00245905'
CONNECT BY PRIOR T.ITEM_NO = T.ITEM_NO_SCO AND PRIOR T.ITEM_TYPE = T.ITEM_TYPE_SCO;
I want to summarize the above the post, you can use START WITH in a stand alone query, in a function etc. But how do you use it in a VIEW?
Thanks,

Hi,
Thanks for the quick replies.
I was more looking for a solution with only SQL i.e I dont want to go for any package or outside variable.
Isn't there a way to achieve this through advanced SQL?
Also why when I create a join in a query having connect by without start with it does a full table scan of the joined table, isnt there a better way to create a join, I mean there is no need to run the whole view at a time, it would be run with a input but why isnt the connect by using to input as a START WITH!
Thanks,
VikramBut the solution is "only SQL", that you have to initialize a variable doesn't change that fact.
If you absolutely can't make that solution work, you could code this in DYNAMIC SQL, but that would much more 'bad' than the suggested implementation.
Why exactly do you need a view at all for this?
SELECT
NVL(C.ITEM_NO_CHILD, I.ITEM_NO)     as ITEM_NO,
NVL(C.ITEM_TYPE_CHILD, I.ITEM_TYPE) as ITEM_TYPE,
CONNECT_BY_ROOT I.ITEM_NO_SCO       as ITEM_NO_SCO,
I.ITEM_TYPE_SCO
FROM isct I,
      icont C
WHERE I.ITEM_NO = C.ITEM_NO(+)
AND I.ITEM_TYPE = C.ITEM_TYPE(+)
start with I.ITEM_NO_SCO = :YOUR_BIND_VARIABLE
CONNECT BY PRIOR I.ITEM_NO = I.ITEM_NO_SCO AND PRIOR I.ITEM_TYPE = I.ITEM_TYPE_SCO;Is about as simple as it gets, no need for a view ... no need for anything flashy. What is your justification behind 'needing' a view for this?

Dynamically displaying SPC Chart Title

Hi
I have created SPC Chart Disply.I did dynamic change of chart types(like xbar,xbar-range). Now i want to reset the Chart title property dynamically. if any methods available.
Thanks in advance.
Regards,
Malini.V

This method and all of the other helpful get/set syntax methods are easy found by using the Script Assistant, which is part of the Productivity Tool installation that you can add to your client workstation by running the Wizard Install link found in the xMII Menu's Visualization Services section.
If you are working on a dynamic SPC charting application you might also be able to learn from some pre-installed content: http://localhost/Lighthammer/Samples/SPC/Servers.irpt

Dynamically set flash chart height?

Hi,
I have a flash chart that includes a selector that alters the query for the chart. Depending on what the user selects, the chart shows a different number of rows (this happens to be a stacked horizontal bar chart, but this could apply to any chart type). I would like to be able to dynamically set the chart height based on the number of rows the query returns. If I set it too small and the user makes a choice that returns a larger number of rows, the chart bars are compressed to the point where the labels are unreadable or omitted altogether. Conversely, if I set the height to a larger value and the user makes a selection that results in a small number of rows, the chart is overly extended and hard to read.
I am able to calculate what I'd like the chart height to be using a page item and a before header process. But I can't figure out how to pass this value to AnyChart. I tried using an item substitution (e.g., &P7_CHART_HEIGHT.) as the value for the chart height on the Chart Attributes/Chart Settings page, but this attribute requires a non-zero numeric value. I tried to figure out if I could alter the chart XML, but could not figure out how to do it and I'm not sure item substitutions would be passed in the XML anyway.
Is there a way to dynamically set the height attribute of a chart at page load time?
Thanks,
Mike

Hi Mike,
You can update the Region Source of your chart, replacing the substitution strings *#HEIGHT#* with the reference to your page item *&P7_CHART_HEIGHT.*. So your chart region source should then look something like the following(note that I've trimmed some lines for display purposes), and when the chart is run it will pick up your setting for the height, based upon the value returned from your Before Header process:
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"

Dynamic web-based Chart-Generation

Hi,
I want to a offer my users a dynamic web-based Chart-Generation.
Actually I'm using Excel for generating charts and display the result in a static HTML-Page.
My goal is the user selects the wanted chart (eg. in a dropdown-menue) and this chart will be created immediately.
The charts are connected to a database where the data have been stored.
Is there existing a Freeware-Tool/Module I can use?
cu
Chris

Before FireFox got SVG and made such things obsolete, I spent a couple of sundays playing around with server-side image generation for prettier flow-charts and UML - see http://www.lapisblue.net/ for examples, http://tincancamera.com/examples/java/lapisblue/image-server/ for source code.
It's nothing special, you're free to use it if you want - the main image generation servlet's ImageServlet; it serves up pngs, and caches and redirects repeated requests; the other servlets have different image generator classes.

Can we see dynamic data on charts using Excel Services

hi all,
i would like to know if there is any option in SharePoint 2013 for developing dynamic "responsive/interactive Charts" with SQL server as data source. And the connection should be there online, i mean the charts should refresh data based on
the SQL data all the time.
When i saw the feature of excel service, i could see only retrieving of data using data connection from sql and after adding that data to workbook, we can create responsive charts with required filters. However, i dint see option of data refresh from external
source without opening the excel work book.
What i want is, once i added the chart using chart webpart, if any new data is added or modified in external data source i.e., like SQL in my case, the chart should automatically updated with new changes in the data.
please let me know if my requirement can be fulfilled using OOB.
thank you beforehand .
Thanks & Regards Raj

Hi ALL,
Linda, I know you are only trying to help but when you answer questions where you don't know the answer you only mislead the user asking the question at best but every one else who reviews the post... we have been performing data refresh on page
render and every 5 minutes by default since SharePoint 2007. We build Business Intelligence Dashboards and Score Cards using Live data with Excel Services, and features like PowerPivot, PowerView
Data in a Microsoft Office Excel workbook that has been displayed in Excel Services can come from two different locations. The data may be stored directly in the workbook, or it may be stored in an external data source, such as in a database or
in an Online Analytical Processing (OLAP) cube.
If the data comes from an external data source, the workbook author or administrator has defined the connection information, often in an Office data connection (.odc) file, which describes how to locate, log in, query, and access the external data source.
When you are connected to an external data source, you can perform a refresh operation to retrieve the updated data. Each time that you refresh data, you see the most recent version of the data, including any changes that were made to the data since it was
last refreshed.
Refresh all connections
On the Excel Web Access toolbar, under the Update menu, click
Refresh All Connections.
Periodic refresh
By using Office Excel 2007, the workbook author can specify that data automatically refreshes at a specified interval after the workbook is opened for each connection in the workbook. For example, an inventory database may be updated every hour, and so the
workbook author has defined the workbook to automatically refresh every 60 minutes. For more information, see Microsoft Office Excel 2007 Help.
A Web Part author can select or clear the Allow Excel Web Access Periodic Data Refresh property to enable or disable this periodic refresh operation, if the property has been defined by the workbook author. When the time interval elapses,
by default, the following refresh alert prompt is displayed at the bottom of the Excel Web Access Web Part:
Refresh data for <List of Connections>? (Now) (Always) (Don't ask me again)
An Excel Web Access Web Part author can also set the Display Periodic Data Refresh Prompt property to control the behavior of the message that is displayed when Excel Services performs a periodic data refresh during a session:
Always      means that the message is displayed with a prompt at each interval.
Optionally      means that a user can choose to continue periodic refresh without displaying a message.
Never      means that Excel Web Access performs a periodic refresh without displaying a message or prompt.
For more information, see
Excel Web Access Web Part custom properties.
I have only listed a couple of the ways you can have Excel services update external data, this is not an exhaustive list

I am using the dynamic signal analyzer.vi but this vi has the output as single precision. How can I change this to DBL precision?

I am using the dynamic signal analyzer.vi but this vi has the output as single precision. How can I change this to DBL precision? If I change the representation from single to double in the AI buffer read.vi labview returns ilegal operation and crash. I have labview 5.1 on windows 95 and one AT-MIO16XE50 DAQ board.
Thanks in advance
Ricardo.

Probably by changing the data type that lvdaq.dll expects to write to is causing the crash. I can't test this since I have only 6.1 installed now. In any case, since the daq card is only 16 bits, the single precision is probably adequate for AI Buffer Read. If you do need the greater precision later on, you should be able to change representation in any one of the upper level VIs.

Start point of signal

Hi everbody,
I want to determine the starting point of signal. For this, What can I do?

You need to provide more information for us to help you. Your question is very vague and you don't provide any screenshots or sample VIs of what you've tried.
Try to give more information about your problem and maybe we can help.

Dynamic title for Chart created by an xml-file in SAP ChartDesigner

Hello everybody.
I created an xml-file with SAP ChartDesigner for using it in my abap program. I import this file as a MIME-Object.
Everything works fine, i declared my charts and all my values.
But now I need a dynamic title on the top.
And know that I can give a title in my xml. But it's not dynamic.
I looked into the xml file and the path for the title is:
SAPChartCustomizing
Elements
ChartElements
Title
and then Caption.
p_ixml_doc = g_ixml->create_document( ).
l_encoding = g_ixml->create_encoding( byte_order = if_ixml_encoding=>co_little_endian character_set = 'utf-8' ).
p_ixml_doc->set_encoding( l_encoding ).
l_chartdata = p_ixml_doc->create_simple_element( name = 'SAPChartCustomizing' parent = p_ixml_doc ).
l_elements =   p_ixml_doc->create_simple_element( name = 'Elements' parent = l_chartdata ).
l_chartelements = p_ixml_doc->create_simple_element( name = 'ChartElements' parent = l_elements ).
l_title = p_ixml_doc->create_simple_element( name = 'Title' parent = l_chartelements ).
l_element = p_ixml_doc->create_simple_element( name = 'Caption' parent = l_title ).
l_element->if_ixml_node~set_value( 'QRK-Mittelwert' ).
In my opinion, it's the right path :/
My other values i declare like this.
l_series = p_ixml_doc->create_simple_element( name = 'Series' parent = l_chartdata ).
l_series->set_attribute( name = 'label' value = 'TO' ).
l_series->set_attribute( name = 'customizing' value = 'Series1' ).
loop at gt_mw into gs_mw.
    lv_tabix = sy-tabix.
    l_point = p_ixml_doc->create_simple_element( name = 'Point' parent = l_series ).
    l_element = p_ixml_doc->create_simple_element( name = 'Value' parent = l_point ).
    l_element->set_attribute( name = 'type' value = 'x' ).
    l_element->if_ixml_node~set_value( lv_tabix ).
    l_element = p_ixml_doc->create_simple_element( name = 'Value' parent = l_point ).
    l_element->set_attribute( name = 'type' value = 'y' ).
    l_element->if_ixml_node~set_value( '35.00' ).
endloop.
It works...and i already checked this solution for my title, but it didn't work.
I call the xml file with the method cl_wb_mime_repository:
CALL METHOD cl_wb_mime_repository=>load_mime
    EXPORTING
      io              = lv_io
    IMPORTING
      bin_data        = lt_xmlr
    CHANGING
      language        = sy-langu
    EXCEPTIONS
      no_io           = 1
      illegal_io_type = 2
      not_found       = 3
      error_occured   = 4
      OTHERS          = 5.
CHECK sy-subrc = 0.
*-- Convert raw to xstring
CREATE OBJECT lo_conv.
LOOP AT lt_xmlr INTO ls_xmlr.
    CALL METHOD lo_conv->convert
      EXPORTING
        inbuff    = ls_xmlr
        outbufflg = 25000
      IMPORTING
        outbuff   = lv_xstr.
    CONCATENATE p_xml lv_xstr INTO p_xml IN BYTE MODE.
Maybe somebody can help me.
Thanks a lot.

I got it!

NiDAQmx and 6220 board - Retriggering to start sampling analogue signals

I have a M series 6220 board with labview 7.
I want to measure analogue signals using a digital trigger - much like the examples given in the library shipped with ver.7. However I want to "retrigger" periodically so that I can sample the my analogue signal each time my external circuit sends a trigger pulse out. This retriggering facility continuing until I press a stop button.
At the moment all I can do is get one triggered set of samples and then the VI stops.
Any code advice or examples would be appreciated.

Charles (labview beginner)

Ive saved it to LV7.0 and attached a gif image in case you have any problems with the VI.

How to programatically (dynamically) change the chart legend ?

How do I add new labels/symbols to the chart legend dynamically ?
I'm creating a scatter graph using the query
select A,B,C from tableX group by A
B is the y-axis, C is the x-axis. Points plotted for each grouping of A will be a different color. I know I can change the color of the point to be plotted thru the format trigger. The format trigger will change the color of the plotted points when there is a change in the grouping of A. My problem is how can I add a new label/color to the legend for each grouping of A as it is plotted ? The number of groupings of A is variable depending on what's in tableX. I need to programatically create the legend (each grouping of A will have it's own label/color) thru the format trigger as I won't know before hand how many groupings of A there will be.

Try with Presentation variables.
