Xaver,

If I'm understanding correctly, you can double-click on the X or Y axis to
bring up the Format Axis dialog box. Choose the color that you want in the
Patterns tab - Lines Color option.

Alternatively, you can add an additional series that runs up the Y axis at
the zero value. You can make color changes to this series just like you
would any others. The effect would be that you are coloring the Y axis at
the zero value.

Hello,

I want to colour the plain at the zero level on the y-axis.

Is this possible?
