Parameters:

elements - parent node to use to add this element where changed

childKey - the property name of this element to use to add it to the parent.

defaultValues - default provider

nativeObject - native object to map java script properties

setBorderDash

public void setBorderDash(int... borderDash)

Sets the line dash pattern used when stroking lines, using an array of values which specify alternating lengths of lines and gaps which describe the pattern.

Parameters:

borderDash - the line dash pattern used when stroking lines, using an array of values which specify alternating lengths of lines and gaps which describe the pattern.

getBorderDash

public List<Integer> getBorderDash()

Returns the line dash pattern used when stroking lines, using an array of values which specify alternating lengths of lines and gaps which describe the pattern.

Returns:

the line dash pattern used when stroking lines, using an array of values which specify alternating lengths of lines and gaps which describe the pattern.

setBorderDashOffset

public void setBorderDashOffset(double borderDashOffset)

Sets the line dash pattern offset.

Parameters:

borderDashOffset - the line dash pattern offset.

getBorderDashOffset

public double getBorderDashOffset()

Returns the line dash pattern offset.

Specified by:

getBorderDashOffset in interface IsDefaultLine

Returns:

the line dash pattern offset.

setBorderJoinStyle

public void setBorderJoinStyle(JoinStyle borderJoinStyle)

Sets how two connecting segments (of lines, arcs or curves) with non-zero lengths in a shape are joined together (degenerate segments with zero lengths, whose specified end points and control points are exactly at the same position, are skipped).

Parameters:

borderJoinStyle - how two connecting segments (of lines, arcs or curves) with non-zero lengths in a shape are joined together

getBorderJoinStyle

public JoinStyle getBorderJoinStyle()

Returns how two connecting segments (of lines, arcs or curves) with non-zero lengths in a shape are joined together (degenerate segments with zero lengths, whose specified end points and control points are exactly at the same position, are skipped).

setCapBezierPoints

public void setCapBezierPoints(boolean capBezierPoints)

Sets true to keep Bézier control inside the chart, false for no restriction.

Parameters:

capBezierPoints - true to keep Bézier control inside the chart, false for no restriction.

isCapBezierPoints

public boolean isCapBezierPoints()

Returns true to keep Bézier control inside the chart, false for no restriction.

true to keep Bézier control inside the chart, false for no restriction.

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.

Specified by:

getCubicInterpolationMode in interface IsDefaultLine

Returns:

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

setStepped

public void setStepped(boolean line)

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

Parameters:

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

setStepped

public void setStepped(Stepped line)

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

Parameters:

line - if the line is shown as a stepped line.

getStepped

public Stepped getStepped()

Returns if the line is shown as a stepped line.

Specified by:

getStepped in interface IsDefaultLine

Returns:

If the line is shown as a stepped line.
