I meant, how do you go from data generation, as you explained above, (and I agree we all best have our own way of doing that), to presenting results with all these nifty graphs? Is there a utility that reads selected data and makes them? Is this part of the test mod? That would truly blow me away, but I'd want to use it with all of Grand Prix Legends OEM-version and mods.
The test mod optionally generates the data into a log file. It is simply a few integer values per line, separated by spaces. Cut and paste into a separate file and then read it with a suitable program (spreadsheet software, scientific computing such as Matlab or R, etc...)
