Hi

A tick is visible where the x-axis touches the y-axis and I want it removed or hidden.
Please see the attached screenshot.

Thanks,
Andre

Edited: Looks like the attachment didn't make it. I am using the category grouping labels on the axis to create the ticks on the x-axis on both sides of the bars. Where this overlaps the y-axis, it is visible. I cannot determine where to set it's color and thickness; if I can do that it may be indistinguishable from the y-axis.
