Minor tick marks

[User (Legacy)]

Hi!

By default, Major and Minor unit are set to 'Auto'.

If the x-axis labels are quite long, 'Auto' selects an appropriate step of

major tick marks.

For example, it may choose the step to be 20.

However, Auto seem to have no effect at all for minor tick marks, i.e. I

never saw the chart to display minor marks when Minor unit is Auto.

So what is the purpose of setting Minor unit to Auto?

Thanks,

Serge
