Dear all,

I have a raster image that contains about 450 000 pixels. The pixels values are decimal.

I have two questions :
1. I want to ask you how to extract all pixel values on function of count? It means that I need as result a table contains the pixel values and the count.

2. I want to make an histogram using these values (pixel value as X axis and Count as Y axis). But I can't use Excel in this case because I have more than 250 values. Do you how to make it using other software perhapes?

best regards
