Axis Label Templates

Axis labels display values for major axis ticks.

To configure labels for individual axes, specify label settings in the valueAxis.label and argumentAxis.label objects. To configure labels for all axes, use the commonAxisSettings.label object. Individual settings take precedence over common settings.

This demo illustrates how you can display custom content for axis labels. To replicate this demo, declare SVG markup within the template option. You can access a label's original and formatted values from template code.
