Tick Properties:

This page allows you to define whether to show major and minor tick marks or not. It also allows you to define the spacing between major ticks and the number of divisions (minor ticks plus one) between major ticks, as well as the properties of the tick lines and their lengths.

The spacing used between major ticks may be dependent of the number of significant figures used in the axis number labels, so you may need to also change that.

The option Set log spacing: together with X log spacing and Y log spacing allow you to define if the spacing of major ticks along an axis are logarithmic. If the axis is scaled logarithmically (that is you've asked for log axes in the data limits tab) then log spacing is the default, otherwise major ticks are spaced linearly.

When spacing logarithmically you can define the separation of the major ticks using X log gap: and Y log gap:. These values are the power of 10 you require between adjacent ticks, so for instance, if you wanted ticks every factor of $10^2$ you'd use $2$.
