Heey everyone, I am currently using a Spider8 and Labview to gain data from sensors, after that i use Labview to process the data to charts or graphs. Alltough I have 2 small problems using a chart/graph: 1: For some charts/graphs i want to use 1 Y-axis (example: volts or current) and 1 X-axis, time. I want this time to be like a clock which only counts seconds (example: 0-100sec), using absolute or relative time for formatting is not an option because they count way too much/fast. There is an example of these kind of charts/graphs in the appendix: currents vs time measurement. 2: For most of the other charts/graphs i want to use several Y-axis (example for a motor: current, RPM and torque) and i want to use a X-axis which can go "back" (example for a motor: rotations). There is an example of these kind of charts/graphs in the appendix: Torque measurement. I dont have any idea of how to do this the right way, so your help is very welcome 😄 Thanks!

Hi grasman, have you read jcarmodys message on how to apply a plot to a y-scale? See attachment on how to plot 2 curves onto one xy-graph and to attach each plot to one scale. I strictly followed the context help of the graph and jcarmodys message... I would also suggest to stay away from express vis: they tend to make more problems than provide help. You are more involved in type conversions (to/from DDT) - using simple wires gives you just more control over whats happening in your code!Message Edited by GerdW on 11-12-2009 09:49 AM

Heey GerdW thanks for your help, i changed the plots to points and now i can see them.

I`ll try to make some sort of buffer to put in all the history.

Thank you very much:D@
