To show only every n'th label on the axis, set the step to n. Setting the step to 2 shows every other label.

By default, when 0, the step is calculated automatically to avoid overlap. To prevent this, set it to 1. This usually only happens on a category axis, and is often a sign that you have chosen the wrong axis type.
