• PieRenderer

  PieRenderer(PieChart plot)

Method Detail

• getStartDegs

   float getStartDegs()

• setStartDegs

   void setStartDegs(float degs)

  Set the starting point in degrees from which series will be drawn in order. The input value must be within the range 0 - 360.

• getExtentDegs

   float getExtentDegs()

• setExtentDegs

   void setExtentDegs(float degs)

  Set the size in degrees of the pie chart, extending from the startDegs. The input value must be within the range 0 - 360. An input value would represent 100% of the pie as a half circle while an input value of 360 would be a full circle.

• getRadius

   float getRadius(@NonNull() RectF rect)

• onRender

   void onRender(@NonNull() Canvas canvas, @NonNull() RectF plotArea, @NonNull() Segment series, @NonNull() SegmentFormatter formatter, @NonNull() RenderStack stack)

  Parameters:

  series - The series to be rendered

  formatter - The getFormatter that should be used to render the series

  stack - Ordered list of all series being renderered.

• setDonutSize

   void setDonutSize(float size, @NonNull() PieRenderer.DonutMode mode)

  Set the size of the pie's empty inner space. May be specified as either pixels or as a percentage. If using PIXELS, the best practice is to specify values in dp using dpToPix. If using PERCENT the value must be within the range 0 - 1. The value being set corresponds to the size of the donut radius relative to the pie's total radius.

• getContainingSegment

  @Nullable() Segment getContainingSegment(@NonNull() 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 beginning 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.
