Change major grid thickness

[s.zahedinejad]

I use xy graph and I need to change major grid thickness (thicken)

How can I change major grid thickness ?

You can't change the thickness.  Change the color instead so the grid is either less noticeable or more noticeable.

The work around is to disable showing the cartesian grid and put your own image of a graph in the middle plot image
