CubicLineChart

public CubicLineChart()

CubicLineChart

public CubicLineChart(XYMultipleSeriesDataset dataset,
                      XYMultipleSeriesRenderer renderer,
                      float smoothness)

Builds a cubic line chart.

Parameters:

dataset - the dataset

renderer - the renderer

smoothness - smoothness determines how smooth the curve should be, range [0->0.5] super smooth, 0.5, means that it might not get close to control points if you have random data // less smooth, (close to 0) means that it will most likely touch all control // points

Method Detail

drawPath

protected void drawPath(Canvas canvas,
                        List<Float> points,
                        Paint paint,
                        boolean circular)

Description copied from class: AbstractChart

The graphical representation of a path.

Overrides:

drawPath in class AbstractChart

Parameters:

canvas - the canvas to paint to

points - the points that are contained in the path to paint

paint - the paint to be used for painting

circular - if the path ends with the start point

drawPoints

protected void drawPoints(Canvas canvas,
                          Paint paint,
                          List<Float> pointsList,
                          XYSeriesRenderer seriesRenderer,
                          float yAxisValue,
                          int seriesIndex,
                          int startIndex)

Draws the series points.

Overrides:

drawPoints in class XYChart

Parameters:

canvas - the canvas

paint - the paint object

pointsList - the points to be rendered

seriesRenderer - the series renderer

yAxisValue - the y axis value in pixels

seriesIndex - the series index

startIndex - the start index of the rendering points

getChartType

Returns the chart type identifier.

Overrides:

getChartType in class LineChart

Returns:

the chart type
