How to display multi-channel image in the 'proxy'?

Question

There're many examples to show how to display composite channels in the 'proxy'. But I don't find any example to show how to display multi-channel image in the 'proxy'. I found that I can use PSPixelOverlay to display alpha channel data like this:
int nSpotChannel = gChannelCount - 4;
PSPixelOverlay* overlay = new PSPixelOverlay[nSpotChannel];
for(int i = 0; i < nSpotChannel; i++){
       if( i != (nSpotChannel - 1) )
             overlay[i].next = overlay + i + 1;
       else
       overlay[i].next = NULL;
       overlay[i].data = gChannelData + (4 + i) * nPlaneBytes;
       overlay[i].rowBytes = gProxyRect.Width() * gDocDesc->depth / 8;
       overlay[i].colBytes = 1;
       overlay[i].r  = 230;
       overlay[i].g = 161;
       overlay[i].b = 174;
       overlay[i].opacity = 255;
       overlay[i].overlayAlgorithm = kStandardAlphaOverlay;
pixels.pixelOverlays = overlay;
Then, Seeing red part, it will trigger a new problem, that is how to get the color value of the alpha channel by plung-in itself? It seems that no channel color value info is in FilterRecord.
If you have other solution, please tell me. Many thanks!

Answer 1

This is what I've been doing - was just curious if there was a way to see a more cohesive image.
If the individual EQ plugins are in fact the answer, is there any way to smooth how the Analyzer displays? The image I posted above, all of the tonal curves are very smooth. The analyzer tool shows a lot of peaks and valleys within the overall curve and it's hard to pinpoint each instrument's "sweet spot." Vocals for example are very hard to spot.
