Plot I-V graph

[aidasaufi]

Hello all, can anybody help me, I think the connection is correct but the graph plot is not appearing. If using index array, how is the connection? Thank you for your help

Hi

You have enabled clear data on each call in the build XY graph function.

Double click this vi on the blockdiagram and yu should be running.

Better is to build the data yourself intead of using an express vi that uses the idiot dynamic dataype.

use two shiftregisters to store the data and build a cluster from that to display

Thank you Mr. Albert, this project where I need to get sensor values from arduino. So I can't build the data myself.  From my block diagram, what should I add or remove to make sure that it will not clear the data?

Add the shiftregisters to your while loop by rightclicking the loop and select add shiftregister twice.

The instead of using the i and the randomize function connect he two values you get from your instrument/arduino to the build arrays and after that feed both arrays to he build cluster that feeds into the xy graph
