Hi, Thank you for your help in advance. I am trying to produce a waveform chart that will change the x axys (time) so that either 1, 30, or 60 minutes of data is in the display area (everything is in seconds, I've been lazy with the math here). The intention is that the user can, at any time, change the x axys during data aquisition. I have not had any luck using the property node's increment, multiplyer or offset properties. Any ideas?
