Like Ton said, they're XY Graphs.  You could have dragged my snippet into your (LabVIEW 2009) block diagram and you'd have had the right indicators automagically. Take a look at the LabVIEW Help on "graphs, types" (in the index); it has a good overview of the different graphs & charts and the data that they'll accept.

You did the peak detection as I did, but you may need to play with the Width and Threshold values for your application.

Hi Please help me in that.. I have some confidence that I can Complete that Project....

Bzzzt - paying someone to complete your assignment is, IMHO, unethical.  I think you'll find it difficult to find someone here to do it for you.

We could provide obfuscated code.  That'd be funny.

Have you determined how many peaks your sample data contains?  How do you know that what you already have isn't exactly what you need?

Hai, I changed the XY graph as shown here in the attachment and I tried to read .CSV file. I don't know whats wrong in that........... Please check it once.

I understand you can't read the CSV file, am I correct?

If so, what OS-language are you on? Could you open the CSV file with notepad and copy the few lines? I think you might have some issues with your decimal sign ('.' or ','). Jim is from the US where they use a '.' as decimal sign and a ',' as field delimiters. I would try to save the file with tabs (/t) as delimiters and remove the ',' string constant from the LabVIEW block diagram.

Ton mentioned that the decimal separator may be an issue.  We use a "." here; what do you use?  Have you tried Ton's suggestion to save the Excel sheet as a tab-delimited text file?

You attached the data but didn't attach your VI. What have you already tried?

If this is what you want, it's really easy . (I saved your Excel file as CSV to make it easier.)

hai.

Can you send the screen shot of the block diagram of this VI? So that I can develop that..
Thanks and regards,

hey please see this once.. it is reading the data... X axis is correct but Y axis values are incorrect. we need to draw two graphs between 1st col and 8th col, 1st col and 9th col.... on X axis it is showing the exact range of value but not in Y axis... Please see this one

First thing you need to make sure that you read the data correct into your VI. It's hard to do that from a graph, so I advice you to place an indicator for the numeric data.

The following snippet should work on all PC's:

Right click on an element inside the array, create property and select the property you need.

But what kind of results do you get, what is 'off'.
Is the data you read allright?

Hi, How can we click the element inside the array? I think we don't have any array elements in my .vi?
