I tried to remove the left and right margins with the following code, but it did not work.
I have set the width of the OuterPosition minus the margins on both sides of the TightInset to the Position, but the left margin does not disappear. Why is this?
When I moved the plot with the mouse, it was exactly the same width as the figure.
In the attached image, the margins are colored for clarity.
plot(rand(1,20))
ax = gca;
ax.OuterPosition(1)=0;
ax.OuterPosition(3)=1;
ax.Position(3)=ax.OuterPosition(3)-ax.TightInset(1)-ax.TightInset(3);
