This page allows you to configure how the axis number labels are rendered. As with other pages you can define the font, style, size and colour used, as well as the separation between the actual axes and the labels. An accurate rendering of how the labels will be drawn is shown in the Sample: label.
The Set log labelling: option controls whether the numbers are drawn using an exponent notation. This is the default if log spacing has been selected for the axis (so you can also use this to not get exponent labelling when the axes are drawn using a log scale).
The Digits: drop down box allows you to override the default number of significant figures shown in the labels. Just choose a number that you want. However, note that the number of significant figures is used in the algorithm for determination how to space major ticks, so it may be necessary to increase this value when configuring the major tick separation.
