In addition to the major grid built on major ticks, the Chart UI component provides the minor grid built on minor ticks.
Neither minor ticks, nor the minor grid can be displayed if the axis is of the "discrete" type.
The commonAxisSettings.minorGrid object specifies common settings for all minor grid lines in the chart. To configure only those grid lines that descend from a particular axis, use the following objects.
Axis-specific settings override common settings.
Displaying the minor grid without the major grid may impair the readability of a chart. To prevent this situation, we recommend you use the minor grid only in conjunction with the major grid.
