[<Dia...@nr...>]

I am trying to find a way of clicking on subject categories underneath =
a pie
chart in order to=20

get to the subcategories indicated by the colors of the pie chart.

http://source.cisti-icist.nrc-cnrc.gc.ca/cs/journals/subjects_e.html

At the moment, one has to click on the different colors of the pie =
chart in
order to go to the subcategories.

If someone is colour blind, it would help to use the text underneath =
the pie
chart in order to go to the subcategories.

How do I do that?

The part of the code for the english pie chart:

PieChart2DProperties p2dProps =3D new PieChart2DProperties();
    PieChartDataSet p2dData =3D new PieChartDataSet("Journal Coverage", =
data,
                                                  labels_e, paints,
                                                  p2dProps);
    LegendProperties lp =3D new LegendProperties();
    lp.setBorderStroke(null);
    lp.setBorderPaint(null);
    lp.setEdgePadding(1.0f);
    lp.setPlacement( LegendAreaProperties.BOTTOM );
    lp.setNumColumns(1);
    lp.setFont(new Font("Arial", Font.PLAIN, 10));
    PieChart2D p2d =3D new PieChart2D(p2dData, lp,
                                    new ChartProperties(), 450, 600);

    p2d.renderWithImageMap();
    ImageMap imageMap =3D p2d.getImageMap();

    StringBuffer ebuf =3D new StringBuffer();
    ebuf.append("<p>\n<img border=3D\"0\" src=3D\"bsubs_e.jpg\" " +
                "alt=3D\"Journal coverage pie chart\" " +
                "useMap=3D\"#chartMap\">\n");
    ebuf.append("<map name=3D\"chartMap\">\n");

    Iterator iterator=3D imageMap.getIterator();
    int i =3D 0;
    while(iterator.hasNext()) {
      StringBuffer html =3D new StringBuffer();
      ImageMapArea imageMapArea=3D (ImageMapArea) iterator.next();
      html.append("alt=3D\"" + imageMapArea.getLengendLabel() + "\"");
      html.append(" href=3D\"" + pages_e[i++] + "\"");
      ebuf.append(imageMapArea.toHTML( html.toString()) + "\n");
    }
    ebuf.append("</map>\n");


    FileOutputStream fos =3D new =
FileOutputStream("journals/bsubs_e.jpg");
    JPEGEncoder.encode(p2d, 1.0f, fos);
    fos.flush();
    fos.close();
