multiple ROIs and their histogram

Hello, now I can get one ROI on screen & get the histogram

 

However I want to analyze several ROIs at the same time, how should I deal with it?

 

I googled about multiple ROIs ,and it seems that I should use UNGROUP ROIs

 

but the connection is incorrect... how to fix it?

 

and after ungroup the ROIs, can I get the histogram mean value from each ROI?

 

Thanks for any advices.

-The Ungroup ROIs output is an array of ROI descriptors.

-Which means you have to index each ROI descriptor and apply to image by using for loop.
