Yes, Sourcetrail also shows class internal calls and accessed fields. Code Maps in VS has a different approach because they try to keep the graph small by making the user add symbols. So if you are trying to see every access of a symbol it is easy to miss something. Sourcetrail on the other hand keeps the graph small and comprehensible by showing only one level of dependencies. You don't need to add anything yourself. So you cannot miss any relation ;)

Thanks. Sounds more promising than I took from you landing page. I will give it a go on my c/c++ code bases. See if it can help me.

I now notice the free trial cannot be run on your own project. I have to say I won't buy anything that I didn't try on a real sample before. What made you decide to go for this option instead of regular limited functionality or time bound (my preference).

Oh, we have a time bound evaluation testing period available: https://www.sourcetrail.com/trial#test-license

How did I miss that? Will try tomorrow!
