Hi all, (please refer to the attached picture) i am trying to create a vi which interfaces with a few nanovoltmeters and current sources for electrical measurements. In essence, I was trying to plot out a I vs V graph. The sequence is as follows ideally: 1) User inputs minimum and maximum current outputs, the number of data points he wishes to obtain for the graph, and the number of times V is read at the same current setting for averaging purposes. 2) VI will take the difference between min and max output, divide it by the number of data points to get each current 'step' 3) for each current step, the Volt is read over 10 times (for eg) and averaged. 4) each average V is paired with the current output and plotted as a point on the XY graph. However, I have been getting very weird results from the way i implemented my VI. Would appreciate anyone who could shed some light into the matter for I must admit that I'm rather weak in the concepts of arrays and indexing. Thanks in advance!

Help with plotting averaged data points in XY graph.

Hi

I've used WinZip 11; optimised for maximum compression.

I only have WinZip 9.2. How 'bout backing off the compression level a bit to something more compatible.

hi

this is it with legacy compression.

beta one and two are slightly different versions of the same thing.
