combine two channels on one graph

[kapishon]

I need to add a second channel, coming from same instrument, to the existing acq&graph Voltage VI (see attachment). I want to get two voltage curves on the same amplitude vs time graph. I configured the second channel and created a task, which also works on a that single channelled VI. Thanks a lot in advance

Hi Vitaliy
you can connect your 2d array directly to the graph indicator.

If that task you created has both channels, then you should be acquiring and displaying both of them with that code.

I have two tasks for each channel. So Im trying to feed those two tasks through one loop and onto a graph. I do have a task named "ai cont multi" in NI-DAQmx Base Config Unility where I can choose two channels, but when I input this task into my VI, it doesn't recognize the resource which is weird cuz It does recognizes single channeled tasks that I created. I think Im missing something fundamental on the block diagram...

I don't use DAQmx Base but I would assume that it works the same as DAQmx and in order to do multi-channel acquisition, you can only have a single task and that single task can contain multiple channels. For example, the channel list would be something like Dev1/ai0:1 or Dev1/ai0,Dev1ai2.

thanks a lot!
