How do you average data being sent to a waveform graph?

[BlingBling]

I am reading a 2D .lvm file with the ReadFromMeasurementFile.vi. I would like to average each signal before passing it to the waveform graph in order to tamp down some of the background noise. Please tell me the best way to approach this.

Use the Mean function or the Statistics Express VI

I do not want to average the data as a whole. I need a running average.

So you are not using the Read From Measurement File to read the entire file? You want to average one segment with the next? If so, you will use a shift register. I would not use dynamic data - just a 2D dbl array.

Here is the code. How would you adust this so that the resulting wave forms are averages based on the previous 10 data points?

[Dennis_Knutson]

There's no code there to modify. You have a single file read and a graph. It runs once and stops. You have nothing to average against.

I would suggest you first spend some time with the basic tutorials then do a search for 'running average'.

Consider using a Median Filter instead of a running average:
