I am trying to draw a long trace with many signals in it with high update rate.
Please have a look at the attached Macro. It contains a macor wich creates a Signaltrace and draws it using a Histogram. The trace consists of 1 Million Points. To fill the Histogram with these points the program needs less than a second. But to draw the Histogram, the program needs ~10s. Is there a way to improve the speed of the drawing process? Or do I have to use another way of drawing?
In the end I’d like to have a Oszilloskop like Display which might have even more than a Million Points in it. The Display should update at least with ~5 Hz. Is this possible using ROOT?
