strange problem with grid lines

[Andrea Ponte]

Hello,
I want produce with jfreeChart a plot that has on the number axis some label that I have in a array of string.
I use a Symbolic Axis. With this Axis I have a pretty good background but there isn't the grid lines that I had with HorizontalNumberAxis why this happens?
Thanks very much Andrea Byez

This is pretty new code that I've not had much chance to review except to see that the demo application runs. I notice there is a method:

public void setSymbolicGridLinesVisible(boolean flag)

Have you tried setting that to true?

Regards,

DG.
