Live Color Histogram

I am using Fiji and trying to analyse color distribution over different patches of images via histogram.

Under Analyze menu i found two options which fulfils my purpose

  • Histogram
  • Color Histogram

Histogram, seems to show histogram properties for gray scale value equivalent of RGB input image. So, i am more interested in using Color Histogram where i have histogram for all the three channels.

Problem is, i am unable find any option like “Live” with Color Histogram, as we have in Histogram dialogue.

Is there any available plugin which can show Color(RGB, HSV, Lab) Histogram for selection ROI in live mode??
