How to change the distance between the graphs on panes?

Question

It's some kind of histogram. I've got MasterPane with two GraphPanes. MasterPane layout is SingleRow. How can I set no gap between panes?

Here's what I mean

masterPane.Margin.All = 0f;
masterPane.InnerPaneGap = 0f;

do not seem to work

Answer 1

Actually, I needed YouRightGraphPane.Margin.Left= 0;. After that just move graph left and right

Answer 2

You also must do this:

YouLeftGraphPane.Margin.Right = 0;
YouRightGraphPane.Margin.Left= 0;

This work for me)
