Method Detail

getLineShape

java.awt.Shape getLineShape(java.util.List<DataPoint> points)

Returns the geometric shape for this line.

Parameters:

points - Points used for creating the line.

Returns:

Geometric shape for this line.

getLine

Drawable getLine(java.util.List<DataPoint> points,
                 java.awt.Shape shape)

Returns a graphical representation for the line defined by points.

Parameters:

points - Points to be used for creating the line.

shape - Geometric shape for this line.

Returns:

Representation of the line.

getStroke

java.awt.Stroke getStroke()

Returns the stroke to be used to define the line shape.

Returns:

Stroke used for drawing.

setStroke

void setStroke(java.awt.Stroke stroke)

Sets the stroke to be used to define the line shape.

Parameters:

stroke - Stroke used for drawing.

getGap

double getGap()

Returns the value for the gap between the line and a point. If the gap value is equal to or smaller than 0 no gap will be used.

Returns:

Gap size between drawn line and connected points in pixels.

setGap

void setGap(double gap)

Sets the value for the gap between the line and a point. If the gap value is equal to or smaller than 0 no gap will be used.

Parameters:

gap - Gap size between drawn line and connected points in pixels.

isGapRounded

boolean isGapRounded()

Returns whether the gaps should have rounded corners.

Returns:

true if the gap corners should be rounded.

setGapRounded

void setGapRounded(boolean gapRounded)

Sets whether the gaps should have rounded corners.

Parameters:

gapRounded - true if the gap corners should be rounded.

getColor

java.awt.Paint getColor()

Returns the paint to be used to paint the line shape.

Returns:

Paint for line drawing.

setColor

void setColor(java.awt.Paint color)

Sets the paint to be used to paint the line shape.

Parameters:

color - Paint for line drawing.
