XY-Graph / Plot legend: How to detect changes in 2nd/3rd/4th ... legend position

[MichaGue_01]

Hello,

I have an XY-Graph with 4 plots. How can I detect, for example, the color change of the second plot in the legend. The active plot, using a property node, is always plot 0. So I am not able to detect changes in the 2nd/3rd ... plot.

Any ideas?

Thanks a lot.

Best regards,

Michael

Hi Michael,

you might write into the ActivePlot property to select which plot you're accessing...

Hi GerdW,

thank you. But I want to detect the active plot by clicking on the coresponding icon in the plot legend. If I read the active plot via property node, the value is always 0. Regardless which icon in the plot legend was clicked.

Best regards,

Michael

Clicking the plot legend doesn't change the active plot. You have to set that property programmatically...

Ok. Thanks a lot.

Is there a work around or trick to get the information which position on the plot legend was clicked to set the active plot programmatically?

Best regards,

Michael
