Set y-axis amplitude on waveform graph to variable

[kimmett]

Hi

I would like to be able to set the maximum and minimum values on the waveform chart's y-axis to a number that is defined by the user earlier in the program (in an earlier subvi) during run-time. I want to be able to use the "V to Torque" value and make that the maximum (and the inverse as the minimum) y-axis scaling on the graph. Is there any way to do this?

I have attached a screenshot of the relevant portion of the code. which currently only takes in the value into the graph and autoscales, which is not what I want.

Please note I am using Labview 8.6.

Thanks.

Hi kimmett,

use property nodes of the chart to set Y scale min/max. Don't forget to switch off autoscaling before...

Hi

I think that's it. Thanks!

If anyone else has the same problem, the property node I used was Y-Scale/Offset and Multiplier/Multiplier. I then had to right click the newly created node and change to write to input my variable.

Thanks again GerdW
