how can I show the peaks on the same graph?

[mbhatti2000]

Dear All,

I would like to display the peaks of a waveform using the "waveform peak detect VI" on the same graph. The "waveform peak detect VI" gives the output of location and amplitude. I want to combine this information and the original graph so I know that the correct peaks have been detected. How can this be done?

sincerely,

Munir.

What is your LabVIEW version? Newer versions allow you to create annotations.

Open the example finder and look for example "Programmatically Annotate a Graph". It will do exactly what you want. 🙂

(in older versions, you could generate labeled cursors)

Please don't attach bitmap images to your messages.  Even though it has a .jpg extension, it is actually a bitmap.  They are too large (1.4MB) and take way too long to download.

Dear Ravens Fan and altenbach,

Thanks for the reply and comments, what I was actually hoping to do is find all the peaks and not just one peak, and diplay it in the graph. I would like to do something just like in the program attached. The problem I have is that I am reading the data from ascii and to join the output from Peak detector VI and the waveform does not combine. Could you help me in this case?

thank you very much. I have also attached the ascii file.

take care,

Munir.
