[sc-users] Plot to an existing window?

[Aaron Gervais <aaron.gervais@xxxxxxxxxxx>]

I haven't been able to find this in the archives and I'm not sure if  
it's possible... Is there a way to plot to a pre-existing window  
repeatedly? I just want to make a simple FM interface with sliders  
for modulator and carrier freqs, and then a spectrogram that changes  
when you move the sliders, so that you can see the sidebands.  
Obviously, plotting to a new window with every change of value for  
the slider would be less than ideal.

Thx
