I’ve one simple question, but after some hours (to be honest days) of google research 'm still unable to solve my problem:
I get a graph as results of an experiment of mine. Just a simple graph. Now I want ImageJ to measure the area unter this graph on particular sections and probably I’m just to stupid to get it. The best tries I got have been via using Analyze>Tools>Line graph (after using threshold till my graph gets red etc.), when a new window opens and I can select some areas under my curve but only the ones “pre-rasterized” by the grid ImageJ uses. I don’t want to do it by selecting areas “free-hand” because of the deviations in measurement…
Is there any chance to calculate my areas of interest in ImageJ or do I have to export the values and do the calculation in Excel?
I attached an JEPG of my graph.
I know for really working with you need a .TIFF or .RAW but for illustrating what my graphs look like it should be ok.
Thank you vermy much for your help an greetings from Germany!
