public class LineDataset
extends LiningDataset
implements HasDataPoints

The line chart allows a number of properties to be specified for each dataset. These are used to set display properties for a specific dataset.
All point* properties can be specified as an array. If these are set to an array value, the first value applies to the first point, the second value to the second point, and so on.

Constructor Detail

LineDataset

public LineDataset()

Creates a dataset.
It uses the global options has default.

LineDataset

public LineDataset(IsDefaultOptions defaultValues)

Creates the dataset using a default.

Parameters:

defaultValues - default options

Method Detail

setXAxisID

public void setXAxisID(String xAxisID)

Sets the ID of the x axis to plot this dataset on.

Parameters:

xAxisID - the ID of the x axis to plot this dataset on.

getXAxisID

public String getXAxisID()

Returns the ID of the x axis to plot this dataset on.

Returns:

the ID of the x axis to plot this dataset on. Default is Scales.DEFAULT_X_AXIS_ID

setYAxisID

public void setYAxisID(String yAxisID)

Sets the ID of the y axis to plot this dataset on.

Parameters:

yAxisID - the ID of the y axis to plot this dataset on.

getYAxisID

public String getYAxisID()

Returns the ID of the y axis to plot this dataset on.

Returns:

the ID of the y axis to plot this dataset on. Default is Scales.DEFAULT_Y_AXIS_ID

setCubicInterpolationMode

public void setCubicInterpolationMode(CubicInterpolationMode mode)

Sets algorithm used to interpolate a smooth curve from the discrete data points.
The following interpolation modes are supported:

 'default'
 'monotone'
 

The 'default' algorithm uses a custom weighted cubic interpolation, which produces pleasant curves for all types of datasets.
The 'monotone' algorithm is more suited to y = f(x) datasets : it preserves monotonicity (or piecewise monotonicity) of the dataset being interpolated, and ensures local extremums (if any) stay at input data points.

Parameters:

mode - algorithm used to interpolate a smooth curve from the discrete data points

getCubicInterpolationMode

public CubicInterpolationMode getCubicInterpolationMode()

Returns algorithm used to interpolate a smooth curve from the discrete data points.

Returns:

algorithm used to interpolate a smooth curve from the discrete data points.

setShowLine

public void setShowLine(boolean showLine)

Sets if the line is not drawn for this dataset.

Parameters:

showLine - false if the line is not drawn for this dataset.

isShowLine

public boolean isShowLine()

Returns if the line is not drawn for this dataset.

Returns:

false if the line is not drawn for this dataset.

setSteppedLine

public void setSteppedLine(boolean line)

Sets If the line is shown as a stepped line.
If the steppedLine value is set to anything other than false, lineTension will be ignored.

Parameters:

line - If the line is shown as a stepped line. false is no step interpolation

setSteppedLine

public void setSteppedLine(SteppedLine line)

Sets If the line is shown as a stepped line.
If the steppedLine value is set to anything other than false, lineTension will be ignored.

public SteppedLine getSteppedLine()

Returns If the line is shown as a stepped line.

Returns:

If the line is shown as a stepped line.
