change properties in stack plots

[peanuts]

hello

I'm using a waveform chart in my VI (labview 6.1).I need to display three graphs with diffrent y-scales.
So I chose Stackplots. The result is one chart with three diffrent output windows. So far so good - but now I need to change the properties of the graphs individually. Primarily I'd like to change the way the displayed points are interpolated.
I've searched for the place where to make this changes but all I found was a way to adjust the first output chart. All other output windows of the stack plot remain with the standard looking. maybe a quite stupid question ...

thanks in advance for any help
Simon

You need to use/set the "Active Plot" property as per the attached.
