The mean circle size is dependent on the width of the box. If the width isn't important to you, try and make the boxes narrower.

Are you using a NumberAxis? If so, you could try: autoAdjustRange() Rescales the axis to ensure that all data is visible. Here's the javadocs for it: http://www.jfree.org/jfreechart/api/javadoc/org/jfree/chart/axis/NumberAxis.html You can get a reference to the axis from the plot object, which you g...

Hi, I also found this post for you: http://www.jfree.org/phpBB2/viewtopic.php?t=12788 It says: Make sure you have tooltips and URLs disabled, those will use a lot of memory at drawing time. If you are displaying the chart in a ChartPanel, you may also need to disable the collection of chart entities...

Hi, can you please explain what you mean by graphical cursor?

'Cause cursor to me means the pointer, like the little arrow you click with on your mouse, or the line that keeps track of where you're typing.

Perhaps there is some other meaning I don't know? Something statistical?

I figured out the problem. SetMargin is actually using a percentage of the available space for bars/boxes. And it's a 0 to 1 percentage, so .5 was way too big. The greater the margin, the smaller the bars/boxes. Also, you don't want to set the margin on the item, that's actually the wrong one. You w...

That's strange, setRange worked perfectly for me... maybe set the beginning range to 19 and see if the 20 showed up? We had a clipping problem at the top of our range, so I just added 5 to the top of the range and anyone who scored 100% will now show the full box.

Or perhaps it would be easier to create a "Floating Bar Chart" where you can set where the bar rendering starts, then the heights of all the bars? Would that be hard? Hi, I figured out a way to do this. You can set the bottom bar to be the size you need the stacked bar to float. Then set the paint ...

Hi, one more thing... looking at Box and Whisker, it looks like you have to give it all the raw values, but for my benchmark / comparison data, all I have is the already-calculated quartile ranges, along with the median. No mean available. Does Box and Whisker always rely on calculating this itself...

How to set width of BoxAndWhisker item?

Hi folks, I am trying to set the width of my BoxAndWhisker items - they are too fat. I tried this, but it has no effect: BoxAndWhiskerRenderer bRenderer = (BoxAndWhiskerRenderer) plot.getRenderer(); bRenderer.setSeriesFillPaint(0, Color.green); bRenderer.setItemMargin(0.5); I'm using jfreechart-1.0....

Sure, that would be nice. I certainly don't have the time to fix that, but maybe someone does.

I was posting my work-arounds so that other people can see them. It's particularly helpful if you are new to JFreeChart like me.

JDBC Datasets

Have you considered using JDBCCategoryDataset or JDBCXYDataset? It will load data from the database for you. I don't know if it's quicker, but it might speed things up a little.

how big is the dataset?
