Hi, I am Avinash, I have ASCII code in EXCEL file with huge data like 60000rows and 9columns. We need to plot graph between 1st column and 8th column , 1st column and 9th column. It should read from 23rd row onwards... after that, It should plot in saparate graphs and have to find the maximum and minimum values of each pulse of the waveform in each graph and should count the pulses in the graph..... I am new to this LABVIEW, please kindly help for my project. This is the final stage of my project. I am attaching the example ASCII file here.. Thanks and Regards, Avinash

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.)

Hey,

It's really surprising.. I am sending my file here.. please see that for required modifications....... and we have to show the maximum and minimum values of each pulse in the waveform and then we have to count the pulses in that two waveforms.

Two things:

1) I didn't post my code because you didn't post yours.  I don't work for free (but I will do my best to help).
2) I don't trust my peak determination.  You'd need to validate the results against a known data set.
c) My program is at work and I'm at home.

I'll do it for $US125/hour.

Just so you know, this is a community forum, so it's more about people helping other people, but contracting opporunities are also welcome - just make it clear that you're looking for a contractor when you post. Posted Image

Actually, I am in need of that to complete my graduation or else I have to do one more semester for this... I completed my whole project except this part.....
But I can't give that much amount. If possible Please help me? I feel great about that.. I can show my code, in which i have done soo far

Showing your code is the least you should do. Please post it with some comments about what is going wrong.

I apparently have lower overhead (or a lower estimation of my own value) so I do side jobs for $75/hr!  But, if you post your code we can help you work through your problem FOR FREE!  You can't beat that price anywhere, and you won't be guilty of academic fraud.  Besides, if you graduate without knowing the material you may end up working with me and I'd have to do your work forever. ;)

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.

That said, as jcarmody said, if you post your code and are open to learning a little, we'll do it for free :)

Hi Avinash,
I cannot really match your question with the code you posted. (could be a language thing.)

Here's your posted code with the actual operations you performed on the data:

Like I said before, you need to specify your requirements for peak detection better.  Perhaps you could manually detect peaks from your sample data and compare my results in the screenshot above.  I used the Peak Detector.vi, but it may not be what you need.  See if you can implement this from my snippet.

Hi, Here I have to plot the graph between first column and 8th column in one graph and 1st column and 9th column in another graph. We have read this data from 23rd row

Hello Jcarmondy,
I have done this one. Please see this and tell me how can i connect the bundle and wave form graph. So, that i can follow your instuction

You should use a XY-graph instead of a waveform graph.

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.
