Hello,
I am new to LabView. I am simultaneously acquiring 4 channels of acceleration time histories using DAQ assistant. I want to rescale each channel with a different factor (associated with different sensitivity of my accelerometers), before presenting all the channels on the same graph. All I managed so far is to rescale all channels with the same factor. Can anybody help? Many thanks.

do you have code for us to see. It would make it much easier to help.

Separate the channels using unbundle or index array, scale each one, then combine again using bundle or build array. Then send to the graph.

Without at least a .png of your block diagram I'll take a guess. You need to use the split signals function.

Please attach an example so we can see your datatypes.
If it's just a 2D array, you can use a FOR loop and multiply with a 1D array of four different values.

Or in the DAQ Assistant, apply a different scale to each signal.
