the anti-aliasing value which can be SWT.DEFAULT, SWT.ON or SWT.OFF.

setAntialias

public void setAntialias(int antialias)

Description copied from interface: ILineSeries

Sets the anti-aliasing value for drawing line.

If number of data points is too large, the series is drawn as a collection of dots rather than lines. In this case, the anti-alias doesn't really make effect, and just causes performance degradation. Therefore, client code may automatically enable/disable the anti-alias for each series depending on the number of data points, or alternatively may let end-user configure it.

Specified by:

setAntialias in interface ILineSeries

Parameters:

antialias - the anti-aliasing value which can be SWT.DEFAULT, SWT.ON or SWT.OFF.

draw

protected void draw(org.eclipse.swt.graphics.GC gc,
                    int width,
                    int height,
                    Axis xAxis,
                    Axis yAxis)

Description copied from class: Series

Draws series.

Specified by:

draw in class Series

Parameters:

gc - the graphics context

width - the width to draw series

height - the height to draw series

xAxis - the x axis

yAxis - the y axis

drawSeriesSymbol

public void drawSeriesSymbol(org.eclipse.swt.graphics.GC gc,
                             int h,
                             int v,

Draws series symbol.

Parameters:

h - the horizontal coordinate to draw symbol

v - the vertical coordinate to draw symbol

color - the symbol color
