public PieRenderer(PieChart plot)

Method Detail

getRadius

public float getRadius(android.graphics.RectF rect)

onRender

public void onRender(android.graphics.Canvas canvas,
                     android.graphics.RectF plotArea)
              throws PlotRenderException

Specified by:

onRender in class SeriesRenderer<PieChart,Segment,SegmentFormatter>

Throws:

PlotRenderException

setDonutSize

public void setDonutSize(float size,
                         PieRenderer.DonutMode mode)

getContainingSegment

public Segment getContainingSegment(android.graphics.PointF point)

Retrieve the segment containing the specified point. This current implementation only matches against angle; clicks outside of the pie/donut inner/outer boundaries will still trigger a match on the segment whose begining and ending angle contains the angle of the line drawn between the pie chart's center point and the clicked point.

Parameters:

point - The clicked point

Returns:

Segment containing the clicked point.

setStartDeg

public void setStartDeg(float deg)

getStartDeg

public float getStartDeg()

setEndDeg

public void setEndDeg(float deg)

getEndDeg

public float getEndDeg()
