Hi,
If you want to plot all data in a graph,but as different plots, then you need to build them into a 2D array and it will plot two plots. Otherwise, you build them into an array and right click on the build array VI and select "Concatenate inputs" if you want to concatenate the two set of data you have.
Please let me know if you have further questions.
Also, you may want to take a look at examples on Development Library.
Sincerely,
Sastry V.
