How to display the core.peak & compressors to the UI?

HISEnberg

I feel as though I have seen posts about this, but is there a floating tile or anything for drawing the peak node from scriptnode onto the UI? Or do we have to use a buffer and panel paint routine to draw this ourselves? I feel like there ought to be a floating tile for this!

@HISEnberg For now, there is no FloatingTile option for this purpose. It is necessary to use Display Buffer.

@orange Thanks that is what I suspected, seems like a proper feature request.

Have you drawn the peak node using a display buffer? I refactored my oscilloscope script but I am still having issues:

The panel doesn't properly display the gain (magnitude) of the peak properly, it simply fills the whole height. I think I need to pull directly from the buffer instead of the node to scale it.
The path disappears when the amplitude hits 0. I am trying to continue drawing the path at the bottom of the panel but it isn't doing this.

@HISEnberg Is there a reason you don't create your path directly from the display buffer?

@ustk I just started working with the Buffer API recently but when I was working with creating the path from the display buffer it kept causing crashes on HISE. Your snippet seems to work perfectly however so I will start from here, thank you!

@HISEnberg Yes creating paths directly from the display buffer is the way to go.
