my task sounds quite easy but I have difficulties to achieving it.
I produce 3 MultiGraphs in 3 Different Root files. I would like to read all three of them in another file and display them in one canvas next to each other. I used https://root.cern.ch/doc/master/canvas2_8C.html as an orientation for splitting the canvas but when I want to draw my multigraph I get the error, that it is pointing to NULL which means that I am reading it out wrong or writing it wrong into the file … I am lost and nobody else seems to have difficulties with that :s
I am attaching the main file
ANTSAll.c (7.5 KB)
Additionally I am attaching one of the three files that produce the .root file (they are nearly the same) together with the input data.
