This property is frequently set on labels by the chart core. When changing its value, be aware that it may already be storing a value for the chart core, and it might get changed again by the chart core. This is particularly true in the case of axis labels.
The best practice for changing this property's value in code is to increment or decrement its existing value, rather than changing it to a new value altogether.
