How do I control the time base of a graph programmatically?

If I'm displaying 4 cycles of a sine wave on a graph, how can I continue to display 4 cycles when the frequency changes?

I'm not sure if this is what you are after or not.  But you can programmatically change the X-Axis of an XY graph using a property node shown below:

Thanks - this worked for me.  However, I  get a flickering effect on my waveform graph.  Any ideas how to fix?

Thanks in advance.

Show us you code. 😉

Make sure to only write to the property when the frequency changes, and not with every iteration of the loop. What is your loop rate?

Thanks for your help.  I solved my problem with an event structure.

Do you know how to attach kudos and problem solved?

To mark the question as solved, mark the green "Accepted Solution" icon on the right hand side of whichever message gave you the solution.  You seemed to have figured out the clicking of the Solved?

If you go to the options menu to the  upper right of your last message, you can unmark your own reply as the solution.  Then you can go and mark the correct reply as the solution.
