Method Detail

createGraphicsCanvas

protected void createGraphicsCanvas()

Creates an instance of Graphics2DPlotCanvas.Graphics2DCanvas which wraps the rendered plot.

Overrides:

createGraphicsCanvas in class GraphicsPlotCanvas

createGraphicsJPanel

protected void createGraphicsJPanel()

Creates an instance of Graphics2DPlotCanvas.Graphics2DJPanel which wraps the rendered plot.

Overrides:

createGraphicsJPanel in class GraphicsPlotCanvas2

draw2DInto

public void draw2DInto(java.awt.Image image)

Draws the plot into the specified image by using Java2D API. Can be used for off-screen renderering if double-buffering is switched off. Otherwise NullPointerException will be thrown.

mapCursorPosition

public GraphPoint mapCursorPosition(int x,
                                    int y)

Maps the cursor position onto a point in device-independent coordinates.

Overrides:

mapCursorPosition in class GraphicsPlotCanvas

Parameters:

x - X-coordinate of the cursor.

y - Y-coordinate of the cursor.

main

public static void main(java.lang.String[] args)
                 throws java.lang.Exception

Shows a plot in a Frame. The plot (data and layout) is defined in the .properties file specified by the first command line argument.

Usage: java jcckit.Graphics2DPlotCanvas [-r <renderer class>] <properties file>

Throws:

java.lang.Exception
