Setgrid()

Hi all,

Is there a way to set grids on the y-axis for specified numbers on a histogram? I know I can right click the canvas and get grid lines for every preset interval, but say I only wanted grid lines for .5, .6, and .7 on the y-axis. Is there a way to do this? Any help is appreciated!

For this you should draw a TLine right position.
