two charts with two image maps in a single jsp page

[jfreeuser2006]

Hi all

i was wondering if anybody can help me out.

how can i show two images with their respective image maps in one page so that both could have tooltips and drill down capabilities?

right now i can only show 1 chart with an image map per page.

a sample code would be great.

thanks in advance.

Something like that

Code: Select all

        ChartRenderingInfo cri = new ChartRenderingInfo();
        String filename1 = "";
        try {
            filename1 = ServletUtilities.saveChartAsPNG(chart1, 790, 430, cri, null);
        } catch (IOException ex) {
            logger.error(ex);
            throw new RuntimeException(ex.getMessage());
        }
        String map1=ChartUtilities.getImageMap("imagemap1", cri);


        String filename2 = "";
        try {
            filename2 = ServletUtilities.saveChartAsPNG(chart2, 790, 430, cri, null);
        } catch (IOException ex) {
            logger.error(ex);
            throw new RuntimeException(ex.getMessage());
        }
        String map2=ChartUtilities.getImageMap("imagemap2", cri);
%>

<%=map1%>
<%=map2%>
<img src="<%=DisplayChart.class.getName()%>?filename=<%=filename1 %> "usemap="#imagemap1">
<img src="<%=DisplayChart.class.getName()%>?filename=<%=filename2 %> "usemap="#imagemap2">

Hi angel,

I was able to show the two charts each with its own imagemap and tooltips.

Thanks you very much. :-)

I have a new question regarding JFreeChart's TextTitle. I've run into a a dead end. I am able to add subtitles to the chart. However I could not format the text. Since TextTitle ignores \t and \u0009 the escape character for tabs.

What I intend to do is have the subtitles have this format:

Code: Select all

     Line 1        20.0
     Line 2        15
     Line 3        3

What I have now is:

Code: Select all

     Line 1 20.0
     Line 2 15
     Line 3 3

I am told that I should subclass Title but i don't know exactly how to do it.
I tried to subclass it but the error that shows is that Title is abstract and that i could not subclass it.

What I did was:

Code: Select all

chart.addSubtitle(new TextTitle(new Title() {
     public void draw(Graphics2D graphics2D, Rectangle2D rectangle2D) {
     }
});

Can you please show me how to properly subclass it so that it recognized the tabs?

Jaypee

Hi,

I'm able to chart two charts with their tooltips my prob is that the png files in temp directory don't get deleted.

I was going over the forums and i read that i should place DisplayChart servlet in the web.xml

Can anybody show me how to properly do it?

Thanks
