ChartPanel--> Print function dark background

[develop]

with this new version (1.0.11) this new dark look and feel for chart looks really cool.
but is there anyway when i click on "Print" button on rightClick menu option in chartPanel, change the look and feel of chart to normal (with light Color background)
before passing to printer ?

I am asking this, because if someone tries to print dark chart then it requires lot more ink and users might not like this.

Thanks

That's a problem I hadn't considered. You would need to modify the ChartPanel code - the methods createChartPrintJob() and print() in particular (both are public methods so you could subclass and override them). You'd probably have to clone the JFreeChart instance, apply a different theme, and use the clone for the printing.

Thanks for reply. i tried to override those method and modified the way you suggested.
below is code for print() fuction

but result is pretty distorted, it does create light background, but other colors are not working properly.
can you tell me what is wrong ??

Code: Select all

public int print(Graphics g, PageFormat pf, int pageIndex) throws PrinterException {
        if (pageIndex != 0) {
            return NO_SUCH_PAGE;
        }
        Graphics2D g2 = (Graphics2D) g;
        double x = pf.getImageableX();
        double y = pf.getImageableY();
        double w = pf.getImageableWidth();
        double h = pf.getImageableHeight();
        try{
        JFreeChart cloneChart = (JFreeChart)chart.clone();
        ChartFactory.setChartTheme(StandardChartTheme.createJFreeTheme());
        ChartUtilities.applyCurrentTheme(cloneChart);
        cloneChart.draw(g2, new Rectangle2D.Double(x, y, w, h), chartPanel.getAnchor(),
                null);
        }catch(Exception e){
            e.printStackTrace();
        }
        return PAGE_EXISTS;
    }
