You use the AxisRenderer class to describe the horizontal and vertical axes of a chart. An axis is responsible for rendering the labels, tick marks, and title along its length.

AxisRenderer objects inherit some of their visual properties from the enclosing chart object. The text format of the labels and title defaults to the CSS text properties of the renderer. You can control the formatting of the axis title separately by specifying a axisTitleStyleName, either on the AxisRenderer or on the enclosing chart.

When positioning and sizing labels, the AxisRenderer takes a minimum amount of the chart's available space. If labels take too much space, then the AxisRenderer scales them. However, the AxisRenderer does not scale the labels to too small of a point size. To increase readability, the AxisRenderer chooses one of the following layout methods based on the one that requires the least scaling:

Render the labels horizontally end to end.
Stagger the labels horizontally in two rows.
Rotate the labels to fit them in the space provided. The AxisRenderer rotates the labels to the minimum angle needed to prevent them from overlapping. The maximum angle is 90 degrees.

The AxisRenderer adjusts the boundaries of the chart's data area to ensure that it can draw the labels without pushing outside of the boundaries.
