How can I reset a waveform chart when I switch from one node to another?

How can I reset a waveform chart when I switch from one node to another? Right now when I switch nodes it jumps to the position of the second node and continues on. I would like it to clear out the previous node before It starts plotting the new node.

Create a property node of the chart.  What you are looking for is History Data (should be at the bottom of the select list).  Wire an empty array to this property.

When I did this it constantly resets the waveform chart. What controls when this is executed?

It happens whenever that part of your code is ran.  Did you put it inside of a loop?  Did you program specific instances when the chart should be reset?
