Labeling the X Axis in a Column Series Line Chart

[aucforum]

Dear Forum Members,

I would like to know how I can Labeling the X Axis in a Column Series Line Chart please?

I can see the Y Axis is defined by VIEW OPTIONS -> Chart columns. However, it seems the underlying table’s table is used by default in the X Axis. How can we specify a column instead please?

Thanks,

Colin.
