MEDM: Hiding waveforms in the Cartesian Plot object

[PaweÅ PrÄdki <ppredki@dmcs.pl>]

Hello,
Is it possible to choose at run-time which waveforms in the Cartesian 
Plot object are visible and which are not?

Suppose I define four different inputs for such an object and want to 
place four buttons which control the visibility of each of these input 
waveforms. Can that be done?

I tried using the Erase option but it clears the whole object and can't 
be used to choose specific waveforms.

Cheers,
