How to prevent dummy data from being displayed on the XY graph

[Connor]

I am setting up a program which will run up to 5 tests for different input condition. The program allows the user to opt out of certain tests. As this will result in 5 sets of data with dummy data for the test being opted out, how do I prevent them from being displayed on the XY graph? Also, is it possible to change the names of the plots programmatically.

If you don't want something to appear in a graph, just don't wire it, you can extract dummy data from the input depending on your option.
Yes, you can change a plot's name programatically, using attribute node plot name, but be sure you select the plot you want to change as active plot before.
Hope this helps
