Is your feature request related to a problem? Please describe.
There are times where a chart will want to keep the axis lines but hide axes tick labels. For instance on very small charts where the values can be described elsewhere.

Describe the solution you'd like
Either allow passing showTicks={false} or something else.

Describe alternatives you've considered
I'm currently using tickFormatter={() => {}} and it does remove the actual labels, but it doesn't remove the spacing.
