Hi Flora,

I haven't updated the document. You might try the Open Office web site - I haven't looked at their spreadsheet format, but I've heard that it is XML based.

Correct. Can you post a bug report at SourceForge?

The marker axis band was implemented for the horizontal axis as a 'proof of concept'. I haven't gotten around to writing the same thing for the vertical axis.

There isn't such a renderer yet...but writing one mostly just involves transposing the drawing code. I'd do it for you if I had the time...

You could put a text annotation at a particular (x, y) location. The plan is to extend the annotations to handle shapes, arrows etc. Just look through the com.jrefinery.chart.annotations package - extending it would be pretty easy (I just haven't found the time yet).

No idea. But a NoSuchMethodError usually signifies a version conflict somewhere. It sure looks like you have JFreeChart 0.9.6, check JCommon and the servlet API version of your application server. Apart from those tips, I can't really help much...

In 0.9.6:

Code: Select all

TextTitle title = myPanel.getChart().getTitle();
if (title != null) {
    String titleStr = title.getText();
}

Your point about what a PiePlot would do with a LineRenderer is well-taken and got me thinking. In my original plan, my answer would be that the PiePlot wouldn't know or care what the LineRenderer is doing, and so the plot would have lines on it. But (here's the scary re-think) perhaps Renderers sh...

Thanks. That character is being added by an incorrect usage of the CRLF converter in the Ant script. I've fixed it now.

The problem is that you have created a new ChartPanel and left it hanging in mid-air doing nothing. You've attached a listener to the panel, but the panel is not displayed anywhere. The ChartFrame class, meanwhile, is displaying a panel that it created for itself to display your chart in. Use the ge...

Other alternatives are to: (1) exclude the source files in com.jrefinery.chart.demo.jdbc.servlet.* from your project. I think that is the only package with classes that reference Batik. (2) use the Ant script to build JFreeChart, I pretty sure it leaves out the servlet demo code. I'll try to remove ...

The only legend implementation at present is the StandardLegend class, and it just displays series names. You could write your own class to replace StandardLegend though...

Try searching for 'DateAxis' plus 'weekend'. You'll find this thread:

Hi Fran, Thanks for your post, I am very interested in what people think about the API. First, a minor one: Eliminate the down-casting convenience methods on JFreeChart that re-cast its Plot. (That is, getCategoryPlot() and getXYPlot()). -These are rather confusing, don't really add any convenience,...

You don't say what the error was, but my guess is that it is a security policy exception, rather than anything to do with JFreeChart directly.
