graph: aquire 2 voltages and display it on a graph: voltage 1 over voltage 2

[bubi]

Hello,

I aquire 2 voltages and want to display them in one graph, that means I want to display voltage 1 on the y-axes and voltage 2 on the x-axes.

What do I need to do?

- do I actually have to use 2 DAQ assistants or can I just set up 2 channels (I am using the UDB-6009)?

- how can I bring one of the voltages to the x-axes (use xy graph etc.)?

I was always only able to display the both voltages on the y-axes with respect to time.

It would be very nice if someone could help me.

Thank you and best regards,

Robin

No, you do not use two separate DAQ Assistants. You just specify two channels to acquire. If you look at the bottom of the channel list when you start the DAQ Assistant, it says to hold down the <Ctl> or <Shift> keys to select multiple channels.

To create an XY graph, the simplest way would be to use the Express XY Graph. Use the Split Signal function to get the different channels from the DAQ Assistant and wire the results to the x and y inputs.
