This is a bit of a workaround, but will hopefully work for your needs! Change the mark type to Circle, Shape or Square. Then, place Feature on the Label shelf. In the Label menu (on the Marks card), choose, Left align. Then, change the color to white.
Hope this helps!
Thanks Tracy. That worked.
I have another problem now. If the text is too long, it gets cut off before the next quarter line starts.
Is there a way to expand the width of the quarters I have in the work book ?
