hi alauddin,

 

your message was notified in my mailer as the message #1000 :-)

 

You can not split the chart and the chart legend produced by JFreeChart, but you can still create the legend by your self using JasperReports.

So, this is my suggestion:

 

1. Create a subreport to show the chart and the legend. You have to put your chart in the title band, and set force the title band to be printed in a separate page (report properties window -> Other options tab).

The chart will be without legend (because we will generate it by ourself). Set the chart element to be printed at "report" time (element properties -> evaluation time). The subreport should be filled using the data used to fill the chart. The legend can be created setting some columns for the report (report propeties -> Columns) in orther to have more records on the same row, and the colors used by JFreeChart to create the chart can be found here:

 

Code:

public static Paint[] createDefaultPaintArray() {

        return new Paint[] {
            new Color(0xFF, 0x55, 0x55),
            new Color(0x55, 0x55, 0xFF),
            new Color(0x55, 0xFF, 0x55),
            new Color(0xFF, 0xFF, 0x55),
            new Color(0xFF, 0x55, 0xFF),
            new Color(0x55, 0xFF, 0xFF),
            Color.pink,
            Color.gray,
            ChartColor.DARK_RED,
            ChartColor.DARK_BLUE,
            ChartColor.DARK_GREEN,
            ChartColor.DARK_YELLOW,
            ChartColor.DARK_MAGENTA,
            ChartColor.DARK_CYAN,
            Color.darkGray,
            ChartColor.LIGHT_RED,
            ChartColor.LIGHT_BLUE,
            ChartColor.LIGHT_GREEN,
            ChartColor.LIGHT_YELLOW,
            ChartColor.LIGHT_MAGENTA,
            ChartColor.LIGHT_CYAN,
            Color.lightGray,
            ChartColor.VERY_DARK_RED,
            ChartColor.VERY_DARK_BLUE,
            ChartColor.VERY_DARK_GREEN,
            ChartColor.VERY_DARK_YELLOW,
            ChartColor.VERY_DARK_MAGENTA,
            ChartColor.VERY_DARK_CYAN,
            ChartColor.VERY_LIGHT_RED,
            ChartColor.VERY_LIGHT_BLUE,
            ChartColor.VERY_LIGHT_GREEN,
            ChartColor.VERY_LIGHT_YELLOW,
            ChartColor.VERY_LIGHT_MAGENTA,
            ChartColor.VERY_LIGHT_CYAN
        };
    }

 

In the next version of iReport you will able to define your own colors. For each record, you have to print country, value and a rectangle with the right color (you can use a conditional style based on the REPORT_COUNT variable to set the right color for each entry.

 

At this point you should have the first three pages.

Put this report in the title band of a new report, forcing agin the title band on a new page.

The rest of this "master" report can be used to print the following pages.
