JFreeChart 0.9.14

Post by **david.gilbert** » Mon Nov 17, 2003 4:32 pm

A new version of JFreeChart has been posted. Changes in this release include:

- implemented zooming for the FastScatterPlot class;
- added item label support for stacked bar charts, and new fall back options for item labels that don't fit within bars;
- modified the CategoryAxis class to allow additional options for the alignment and rotation of category labels;
- addition of the AxisState class, used in the drawing of axes to eliminate a bug when multiple threads draw the same axis simultaneously;
- provided additional attributes in the DateTickUnit class to improve labelling on a segmented DateAxis;
- added support for GradientPaint in bar charts;
- updated the PNGEncoder;
- fixes for tick label positioning on axes;
- various Javadoc updates;
- numerous bug fixes;

You can download the code from the project page at SourceForge:

SymbolicAxis seems to be broken totally in release 0.9.14; it does not draw labels any more

Use any of the corresponding standard demos to see that. I added this remark in sourceforge too: http://sourceforge.net/tracker/index.ph ... tid=115494

It is fixed now and committed to CVS for the 0.9.15 release. You just need to change the refreshTicks(...) method as follows:

Code: Select all

    /**
     * Calculates the positions of the tick labels for the axis, storing the results in the
     * tick label list (ready for drawing).
     *
     * @param g2  the graphics device.
     * @param cursor  the cursor.
     * @param plotArea  the area in which the plot (inlcuding axes) should be drawn.
     * @param dataArea  the area in which the data should be drawn.
     * @param edge  the location of the axis.
     * 
     * @return A list of ticks.
     */
    public List refreshTicks(Graphics2D g2, 
                             AxisState state,
                             Rectangle2D plotArea, 
                             Rectangle2D dataArea,
                             RectangleEdge edge) {

        List ticks = null;
        if (RectangleEdge.isTopOrBottom(edge)) {
            ticks = refreshTicksHorizontal(g2, state.getCursor(), plotArea, dataArea, edge);
        }
        else if (RectangleEdge.isLeftOrRight(edge)) {
            ticks = refreshTicksVertical(g2, state.getCursor(), plotArea, dataArea, edge);
        }
        return ticks;

    }

Sorry for the inconvenience.

I used...

java -cp jfreechart-0.9.14.jar;jfreechart-0.9.14-demo.jar org.jfree.chart.demo.Pie3DChartDemo1

...and was expecting to see the 3D pie chart like the first one on the samples page (http://www.jfree.org/jfreechart/samples.html).

But it has no depth...is this a bug or how can you give them depth?

Thanks.

minor quibble: JavaDoc in 14 is broken.

the file URLGenerator is the problem. need to comment it back in (or delete it). then everyhting is happy.

/**
* Base interface for URL generators.
*
* @author Richard Atkinson
*/
//public interface URLGenerator {

//}

Thanks for the report, it has been removed for the 0.9.15 release.

jfreechart-0.9.14.tar.gz seems to be corrupt from the jfree.org site and missing from the sourceforge mirrors. The .zip file works well, though.
