waveform updated during measurement

Solved!

Hello, I have attached a file from the VI examples, the VI is a 2-channels sweep for FET characterization. I see the plot is generated at the end of the data acquisition.

Is there a way to see the plot updated in real time? so that every point is plotted during acquisition? Thank you for your support...

Just maintain the XY arrays in a shift register.

Dear crossrulz, thank you for your suggestion. I failed to try this way because the library niDCPower Measure Multiple.vi looks like to collect all the data and send them outside the for-loop at the end of the collection, so I cannot find the shift register terminal to link to...

Move the graph INSIDE the loop.  And build the array and maintain in a shift register.  There is no shift register in there to add to.  You need to create it yourself!
