saving a waveform in LV 7.1

Hello

I need to know about the saving of a waveform in JPEG or in Excel  or any other format.

If you want a picture then you can use the Get Image method for a graph and feed the image data to a Write JPEG File VI.

If you want numeric data then you can use the Write To Spreadsheet File VI. This does not create an Excel file. It creates a text file with delimited columns, but you can open it with Excel. If you absolutely want Excel then you will have to use ActiveX. Examples ship with LabVIEW, and you can find more in the Excel thread.

As mentioned on the link, it is a method of a control. You must not have read anything there. The very first line says "Returns an image of a front panel object." and then it says it is similar to the Get Panel Image method. It's pretty plain to understand I think.

If you want an example, just open the block diagram of Append Control Image to Report.
