Configures the minor grid.

Type: Object

In addition to the major grid built on major ticks, the Chart widget provides the minor grid built on minor ticks.

DevExtreme HTML5 Charts MinorGridLines

NOTE: 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.

NOTE: 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.
