I am trying to separate data I am acquiring from two analogue inputs on my NI USB-6009 in order to plot them againt one another on an XY graph. I have tried setting up two DAQ assistants on the block diagram, one acquiring data from ai0 and the other from ai1. I tried to wire these to the X input and Y input respectively and running in a while loop but Error -50103 shows up.
I've read through a few discussion threads and have found that you should acquire the data from both analogue inputs thorugh one DAQ assistant, useing index arrays to split the data and wire to the X input and Y input of the XY graph, but I cannot figure out how to do this.
Any help would be greatly appreciated!
