I'd like to show Major and Minor gridlines on a chart in the reporting module. This can only be done via script customisation on the jFree chart.

The jFree Chart documentation [JFreeChart 1.5.0 API](https://www.jfree.org/jfreechart/api/javadoc/index.html) outlines that a DateAxis class has some Minor Tick methods like setMinorTickCount()

However, Ignition seems to not detect any of these MinorTick methods as part of DateAxis. When I print the directory of DateAxis in scripting console, I can confirm that they don't show up.

I've noticed the Vision charts don't have Minor Tick options either.

Is this a version problem?

The version of JFreeCharts packaged with Ignition is v1.0. Newer would be a breaking change.

Thanks Phil. It's a bit misleading when the manual points to the 1.5 documentation
