Method Detail

draw

double draw(java.awt.Graphics2D g2,
            java.awt.geom.Rectangle2D plotArea,
            java.awt.geom.Rectangle2D axisArea,
            RectangleEdge edge,
            AxisShapeCollection shapeCollection,
            boolean alignEdge)

在图表的plot区域(plotArea)绘制X轴或Y轴.图表中的所有图形存放在shapeCollection集合中.

Parameters:

g2 - Graphics2D 图形设备(打印机或屏幕) (不可为null).

plotArea - Rectangle2D 图表的plot区域.

axisArea - Rectangle2D 剩余的空白区域.

edge - RectangleEdge 坐标轴的位置.

shapeCollection - AxisShapeCollection 坐标轴图形集合.

alignEdge - boolean 本标志控制如果实际绘制区域小于坐标轴区域,是否自动靠边界.

Returns:

double 轴实际绘制的宽度或高度.

calculateAxisSpace

double calculateAxisSpace(java.awt.Graphics2D g2,
                          java.awt.geom.Rectangle2D plotArea,
                          java.awt.geom.Rectangle2D maxAxisArea,
                          RectangleEdge edge)

计算绘制坐标轴所需要的宽度或高度.

Parameters:

g2 - Graphics2D 图形设备(打印机或屏幕) (不可为null).

plotArea - Rectangle2D 图表的plot区域.

maxAxisArea - Rectangle2D 坐标轴的最大区域,肯定小于plotArea.

edge - RectangleEdge 坐标轴的位置.

Returns:

double 宽度或高度.

getFixedAxisSpace

double getFixedAxisSpace()

返回固定的坐标轴绘制宽度或高度.

Returns:

double 固定的坐标轴绘制区域 (可为null).
