# navigator.yAxis.minorTicks

Enable or disable minor ticks. The interval between the minor ticks can be controlled either by the minorTicksPerMajor setting, or as an absolute minorTickInterval value.

On a logarithmic axis, minor ticks are laid out based on a best guess, attempting to enter an approximate number of minor ticks between each major tick based on minorTicksPerMajor.

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