using ring to plot a csv waveform graph

[Bob_Schor]

Can you attach a Data File?  I thought the file labelled "EMG.csv.zip" would have been a Data File of "EMG.csv", a comma-separated values file, but it contains "exra.vi", a LabVIEW file.

It would be very helpful to have some data, and to use the data to show you how to do rms and avr (which, I assume, means "average", but what do you mean to do?  Do you want simply the mean of all the data, i.e. a single number?  And what do you mean by rms, again, do you want a single number?)

If you do want a single average of your data, just sum the data points and divide by N, the number of samples.  RMS is the "root-mean of the squares", i.e. you square the data points, average, and take the square root.

rms(root mean square value) and avr(average value). sorry I was in rush and uploaded the wrong file I'll attach the file for the emg data. Yes I do need a single value for rms and avr. sorry for the wording of my question.

Thank you for taking the time and trouble to upload three files, EMG1, EMG2, and EMG3, that are all identical and have a length of 0 bytes.  Why are you wasting our time?

sorry about the empty file I didn't check them before sending. my head is all over the place right now i'm try to finish up with code and study for finals. truly sorry.

I need help calculating the root mean square and average value of the emg.csv files. i'll attach the files. thank you

Hi zoe,

what's wrong with you?

Why do you still create new threads for the very same topic instead of sticking with your original thread? Even after being told so?

I need help calculating the root mean square and average value of the emg.csv files.

Do you need something like this:

I guess the first column in your csv file is just a time column...
