Axis Unit

The AxisUnit node controls placing of a unit tag on an axis. The tag is the value of the Title attribute in the node. By default, it is empty.

The axis unit is used for labeling only; it has no other effect on the chart.

Setting the Axis Unit

In this example, the axis unit for the x-axis is set to "hours" and the axis unit for the y-axis is set to "meters". While not required, the axis titles are also set.
