Q:

Show the Y-Axis line in ZedGraph

In the picture above, there is a line for y = 0 (marking the x-axis).  There is none for x = 0 (marking the y-axis).  How do I get one to appear at x = 0?
I've tried... 
MyZedGraphObject.ZedGraphControl.GraphPane.YAxis.IsVisible = true;
MyZedGraphObject.ZedGraphControl.GraphPane.YAxis.Scale.IsVisible = true;

Neither seem to work.  The color for the y axis is black, so it's not a fully transparent color.

A:

Set the YAxis.Cross property to the desired X value. For example, the following code:
MyZedGraphObject.ZedGraphControl.GraphPane.AddCurve(
    null, new[] { -0.3, 0.5, 0.9 }, new[] { 0.8, 0.3, 0.1 }, Color.Blue);

MyZedGraphObject.ZedGraphControl.GraphPane.YAxis.Cross = 0.0;
MyZedGraphObject.ZedGraphControl.GraphPane.AxisChange();

would yield the following graph:
