Referring to example:
Notice that with this example the axes and axes labels are in white.
After looking at the on-line documentation and the class header file, I can’t determine how to change the color of the axes and their tick marks. I can change the color of the labels. I can draw grid lines in any color I choose. But, so far have not found how to change the color of the axes and the tic marks. How can I do this?
