IlvDataInterval	computeVisibleRange(IlvChart chart, IlvAxis axis, Rectangle oldDrawRect, Rectangle drawRect) Computes the new visible range for the specified axis.

Field Detail

DEFAULT_POLICY

static final IlvChartResizingPolicy DEFAULT_POLICY

A default resizing policy that expands the visible range of coordinate axes when a chart area is resized. The new visible range is computed so that the scaling factor of the Cartesian projection keeps the same value.

Method Detail

computeVisibleRange

IlvDataInterval computeVisibleRange(IlvChart chart,
                                    IlvAxis axis,
                                    Rectangle oldDrawRect,
                                    Rectangle drawRect)

Computes the new visible range for the specified axis.

Parameters:

chart - The chart with which the axis is associated.

axis - The considered axis.

oldDrawRect - The drawing rectangle of the chart area before it is resized.

drawRect - The drawing rectangle of the chart area after it is resized.
