Using ChartPanel

Hi, I have troubles combining ChartPanel with any other swing components in a JApplet. Whatever component I add first gets 100% of the applet paintable area... how can I get the ChartPanel to play nice with other components in the same layout?

Separate jsp

You need one jsp for the page, and another (servlet or jsp) for the chart.
Servlets are preferable for the chart, as per the spec you are not supposed to be able to send binary output from a jsp, although Resin doesn't seem to have a problem with it, I do it all the time.

Show value and percentage on bar chart

I need help figuring out how to do a custom itemLabelGenerator. I would like the label to include the numerical value and it's percentage of some other value. E.g a bar chart with

Item A XXXXXXXXXXXXXX 1000 (100%)
Item B XXXXXXXXXXX 777 (77.7%)
Item C XXXXX 333 (33.3%)

Thanks.

Labels On Bars

Here's an example of labels on bars. No idea on 'if over certain threshold'.

Code: Select all

    BarRenderer renderer = (BarRenderer) plot.getRenderer();
    renderer.setItemLabelGenerator(
       new StandardCategoryItemLabelGenerator(
          new DecimalFormat("###")
       )
    );
