Hi Experts,
I have question concering TF1 class. I have a complicated class that plot my function in form of TF1, one of those complicated classes used complicated math (integrals) to calculate value of the function, another class have analytical form.
Both classes are drawn and looks ok, however when I save my canvas as root file this complicated class is drawn as zero. I do not want to send entire code, but I would like to know how TF1 is saved, as a points? or as a function that is evaluated? This would help me solve issue with saving functions.
Please read tips for efficient and successful posting and posting code
