Making a graph with a voltage input on each axis with a continous curve display

Question

I need to make a graph that can display two voltages, with one of the voltages on each axis.  I have accomplished this by using an xy graph.  The problem is I need a curve to be displayed as the voltages change similar to the curve displayed in the waveform chart.  Currently, a line is displayed between the inital point and the final point but it then disappears.

Answer 1

Hello again.
I should have explained my example more.  I used the same signal for both the X and Y inputs of my XY graph, so the linearly increasing line is expected behavior.  In order to do what you want, you need to use a split signal VI after the DAQ Assistant express VI.  Once you place the split signal VI on the block diagram you can expand it so that it has two output nodes and wire them to the X and Y input terminals of the Build XY Graph express VI.
Similarly, for the array example, you can use the split signal and then use two build array VIs.   In order to reset the graph you can just initialize the shift registers with a zero to clear the graph each time it runs.  This will clear the graph at the beginning of each run (and not at the end).
