public class PieMapper

PieChart Segment Selection Management.

Constructors

`public void setDimensions(int pieRadius, int centerX, int centerY)`	Set PieChart location on screen.
`public boolean areAllSegmentPresent(int datasetSize)`	If we have all PieChart Config then there is no point in reloading it
`public void addPieSegment(int dataIndex, float value, float startAngle, float angle)`	Add configuration for a PieChart Segment
`public void clearPieSegments()`	Clears the pie segments list.
`public double getAngle(Point screenPoint)`	Fetches angle relative to pie chart center point where 3 O’Clock is 0 and 12 O’Clock is 270degrees
`public boolean isOnPieChart(Point screenPoint)`	Checks if Point falls within PieChart
`public` `SeriesSelection getSeriesAndPointForScreenCoordinate(Point screenPoint)`	Fetches the SeriesSelection for the PieSegment selected.
`public` `Shape getSegmentShape(int dataIndex)`

public PieMapper()

public void setDimensions(int pieRadius, int centerX, int centerY)

Set PieChart location on screen.

public boolean areAllSegmentPresent(int datasetSize)

If we have all PieChart Config then there is no point in reloading it

true if cfg for each segment is present

public void addPieSegment(int dataIndex, float value, float startAngle, float angle)

Add configuration for a PieChart Segment

public void clearPieSegments()

Clears the pie segments list.

public double getAngle(Point screenPoint)

Fetches angle relative to pie chart center point where 3 O’Clock is 0 and 12 O’Clock is 270degrees

angle in degress from 0-360.

public boolean isOnPieChart(Point screenPoint)

Checks if Point falls within PieChart

true if in PieChart

public SeriesSelection getSeriesAndPointForScreenCoordinate(Point screenPoint)

Fetches the SeriesSelection for the PieSegment selected.

screenPoint Point

null if screen point is not in PieChart or its config if it is

public Shape getSegmentShape(int dataIndex)
