I'm using the iText library and the JFreeChart draw(Graphics2D g2, Rectangle2D area) method to draw a plot to a pdf file so that they can be edited in Adobe Illustrator. The chart being drawn is being displayed in a ChartPanel at the same time. If I draw the pdf on the EDT my GUI freezes up, but I'm...

Hi, Just wanted to let you know that I'm fairly sure there is a bug in RendererUtilities.findLiveItems(). When searching for live items, dataset.getXValue() is called. If the dataset is an XYIntervalSeriesCollection, this means that an item is only considered live if the x midpoint is in the plot (a...

Cool. If you want to, post a diff of the changes you made and I'll update the class for the next release. I'd be happy to help, but my code is actually specialized to deal with only the type of polygon that my project utilizes... I'm not sure it would work for all cases. Plus, I'm a rather amateur ...

Thanks David. I overrode the XYPolygonAnnotation draw() method and did as you suggested, and the problem is fixed. As an aside, I also added in a method that checks whether the annotation falls within the viewing area and returns immediately if it does not (saving several rather expensive JavaTo2D m...

I have a DomainAxis that is extremely long (1-250,000,000). When I zoom to small windows of this domain (e.g. < 200), my XYPolygonAnnotation that spans the entire axis is not drawn for some - but not all! - of the window sizes (e.g. 45 no, 31 yes)... I strongly suspect that there is some sort of rou...

Ah... not quite sure how I missed that.

Thanks.

I have a heavily customized XYPlot that contains a large number of XYPolygonAnnotations. I'd like to handle tooltip generation in a manner similar to that allowed for the XY data in an XYPlot... but I can't find any mention of such a capability in the developer's guide. Am I missing something? Or do...

I'm curious if anyone could recommend an efficient way to accomplish this. I have a graph with a very large range on the x-axis that can be viewed by zooming in and scanning along the axis. I'd like to prevent the connection of lines between points in my XYSeries if they are separated by a large dis...

Thank you David, that works perfectly. I thought I had tried that before, but I realize now I probably set the autofillpaint. Any thoughts on my request from my initial post? I often find that I want to add something to a dataset and then immediately require the index. It would be great if the stand...

Thanks. I'll give it a shot.

I have a XYLineAndShapeRenderer that needs to paint all series black. This works fine with the deprecated setPaint method, but when I use setBasePaint it does not work (each XYSeries is a different color). The note for the deprecated method says: Deprecated. This method should no longer be used (as ...

Hmmmm.. still no comments. I acknowledge that this isn't a hugely important issue, but I'm fairly sure it points to some sort of underlying bug. I went ahead and submitted the issue to SourceForge. Here is the link if anyone wants to check the status: https://sourceforge.net/tracker2/?func=detail&ai...

I have encountered what might qualify as a bug in JFreechart 1.0.11. I have an XYPlot with a very large domain number axis (integers from 1 - 1,000,000). I place an XYLineAnnotation spanning the full length of this axis. If I use a standard basic stroke (e.g. new BasicStroke(1)), I have no troubles....

Thanks for the reply David. I will give the ClusteredXYBarRenderer a try. but what is the rule you are using to determine the bar width? Because the bars tend to be spaced at roughly increments of 100 along my giant X-axis, I'm scaling them based on the span of the visible x-axis. Anyway, it isn't t...

Hello, I have the developer's guide, and with its assistance I was able to extend XYBarRenderer and override the drawItem() method to suit some of my needs. However, I'm still a bit unsure of the best way to achieve the type of display I require, and I could use some advice. I have a dynamic plot in...
