How to programmatically change plot legend

[Dave Greenwood]

I have a chart on which I'll plot one or more signals. I can't predict
the signal names in advance so I'd like to programmatically change the
legend(s). Is there a way to do that in LV 6.1?

Thanks,
Dave

Yes.

- Create a property node for the chart
- add elements for "Active Plot" and "Plot -> Plot Name"
- Wire an index of the plot name you want to change to "ActPlot"
- Wire an string with the new name to "Plot.Name"

A simple implementation would be to make an array of new names and then auto-index a for loop with the increment counter tied to "ActPlot".

Good luck.
