# colorAxis.minorTicks

Enable or disable minor ticks. Unless minorTickInterval is set, the tick interval is calculated as a fifth of the `tickInterval`.

On a logarithmic axis, minor ticks are laid out based on a best guess, attempting to enter approximately 5 minor ticks between each major tick.

Prior to v6.0.0, ticks were unabled in auto layout by setting `minorTickInterval` to `"auto"`.

On axes using categories, minor ticks are not supported.
