I want to know how to change the size of the graph created by root.
Can anybody help me?
What do you mean by “size of a graph” ?
-number of points
-xmin,xmax,ymin,ymax to draw the graph
When I draw the graph using a root program its too big. I need to change the length & width of canvas. I donno how to do it
See example in tutorial gerrors2.C
