Re: Scrollbar in a line chart
We need to see the code you used with the JScrollPane.

Re: Text alignment problem in OpenJDK
JFreeSVG 2.0 is a big improvement. The vector option did confirm the correct font is being used but we can't use that as the text needs to be selectable for copy/paste.
I'll update the thread if I figure out a solution.

Text alignment problem in OpenJDK
https://dl.dropboxusercontent.com/u/7888334/rendering.png Running JFreeSVG on AWS/OpenJDK 1.7.0_51 and the text measuring appears to be off quite a bit (see the left chart in the image above). The chart on the right was generated on my Windows development machine running identical code. My first th...

Re: Duplicate ids under <defs>
This could also be handled automatically by default, while providing the ability to set a custom prefix. When testing a fix for this myself I used the system time as the prefix.

Duplicate ids under <defs>
When showing more than one SVG document on the same page the shared resources under <defs> have duplicate ids. This is especially problematic with clip refs. We need a method to set a prefix that will be used when creating ids for clips and paints.

shape-rendering attribute
https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/shape-rendering I think this should be set to "crispEdges" for horizontal and vertical lines, rectangles, and Path2D shapes made up only of horizontal and vertical lines. The result looks considerably better for almost all JFreeCharts I hav...

Center Gradients from JFreeChart
I needed a solution that would display the center vertical and center horizontal gradients from JFreeChart in SVG. As you rightly pointed out some months ago this is not straightforward. What I ended up doing was allowing JFreeChart to work with LinearGradientPaint and adding that as a supported gra...

Re: JFreeSVG 1.8
Thanks for the updates David. Love the map option with KEY_BEGIN_GROUP. Support for custom key/values as part of that would be useful. This is the kind of thing I have in mind: String groupId = null; String ref = null; List<Entry> keyValues = null; if (hintValue instanceof String) { groupId = (Strin...

Re: Align Rectangles to bars of BarChart
As David said in the linked post, you'll most likely need to override the draw() method of the JFreeChart class to accomplish this. Note that this method allows you to provide a ChartRenderingInfo object. You can use this to get the position of various entities drawn, including the bars. You'll need...

Re: Align Rectangles to bars of BarChart
Have you considered Annotations?

You could override the draw method to do additional formatting.

Re: XYLineChart- smooth line, XYSplineRenderer not working
You have two points, p1 and p2, the points before and after (p0 and p3) are used as control points for constructing the interpolation between p1 and p2. If you want more details you can follow the link from my original reply. There is a variable called tension which is set to a default value of 0.5....
