Box.getHeight

ChartDirector Ver 3.1 (PHP Edition Edition)

Box.getHeight

Usage

getHeight()

Description

Get the height of the box.

In some usages, the height of a box may be dynamically determined. An example is the width of an LegendBox, which cannot be known until all data are available. In these cases, the width is undefined until the chart has been laid out (using BaseChart.layout) or the chart image has been drawn (eg. using BaseChart.makeChart, BaseChart.makeChart2 or BaseChart.makeSession).

Arguments

None

Return Value

The height of the box in pixels.
