成员函数说明

void com.ab.view.chart.PieMapper.addPieSegment ( int  dataIndex, float  value, float  startAngle, float  angle  )

inline

Add configuration for a PieChart Segment.

参数

dataIndex	the data index
value	the value
startAngle	the start angle
angle	the angle

boolean com.ab.view.chart.PieMapper.areAllSegmentPresent ( int  datasetSize )

inline

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

参数

datasetSize

the dataset size

返回

true if cfg for each segment is present

void com.ab.view.chart.PieMapper.clearPieSegments ( )

inline

Clears the pie segments list.

double com.ab.view.chart.PieMapper.getAngle ( Point  screenPoint )

inline

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

参数

screenPoint

the screen point

返回

angle in degress from 0-360.

SeriesSelection com.ab.view.chart.PieMapper.getSeriesAndPointForScreenCoordinate ( Point  screenPoint )

inline

Fetches the SeriesSelection for the PieSegment selected.

参数

screenPoint

- the user tap location

返回

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

boolean com.ab.view.chart.PieMapper.isOnPieChart ( Point  screenPoint )

inline

Checks if Point falls within PieChart.

参数

screenPoint

the screen point

返回

true if in PieChart

void com.ab.view.chart.PieMapper.setDimensions ( int  pieRadius, int  centerX, int  centerY  )

inline

Set PieChart location on screen.

参数

pieRadius	the pie radius
centerX	the center x
centerY	the center y

类成员变量说明

private

The m center y.

int com.ab.view.chart.PieMapper.mCenterY

package

int com.ab.view.chart.PieMapper.mPieChartRadius

private

The m pie chart radius.

List<PieSegment> com.ab.view.chart.PieMapper.mPieSegmentList = new ArrayList<PieSegment>()

private
