Programmatically formatting the active plot and plot legend

[Stuart Wilson]

I am monitoring 6 production sequences on an XY graph. A ring control selects which sequence I show on the graph. For each sequence I have tag data showing the "actuals" and tag data showing the "averages" and a boolean toggle switch controls which of these plots I show on the graph. I am having trouble controlling the formatting of the plots (both actuals and averages are currently shown in white) and the plot legend is wrong. I have tried programming my vi to format my plots using a property node from the XY graph and writing to the correct plot inputs, however it doesn’t seem to be working. I would also like the plot legend to show ONLY the active plot on the XY graph.

I would like a red continuous line for the averages and blue square scatter points for my actuals. I can’t seem to get this at all. I have attached my vi if anyone can help?

Many thanks for taking the time to help,

Best regards,

Stuart

It is very easy all you have to do is set the active plot first then set all the plot attributes ie name color and so on like you are doing now. After you do that it should work just fine.

Thanks jhoskins, how do I "set" the active plot? What number do i use? Also, how do i show only the active plot on the plot legend? Do i write the same number to legend plots shown as i do for active plot? I am a little unclear on what steps i should take to achieve your suggestion. Any further help is greatly appreciated. Thanks again, Stuart

Hi Stuart,

  The information you need is covere in the LabVIEW Basics II manual, chapter 3 which discusses in detail the Graphs and Chart properties.
