Method Detail

format

String format(AxisLabelsData axisLabelsData)

A subset of HTML is supported. The HTML of the label is parsed and converted to SVG, therefore this isn't a complete HTML renderer. The following tags are supported: <b>, <strong>, <i>, <em>, <br/>, and <span>. Spans can be styled with a style attribute, but only text-related CSS that is shared with SVG is handled.

Available data provided in the given "AxisLabelsData" object are:

• value : The numeric or categorical string value to display.

Parameters:

axisLabelsData - An object containing all of the data available to the formatter that it can use to determine which text and styling to use for the label.

Returns:

The text to display for the label (including any styling).
