Thanks for the reply David. I'll have to try doing it the way you suggested.

I should have elaborated a little bit on how exactly to see the problem. If you hover your mouse over Y = 75 (according to where the tick mark on the axis is) the value provided by java2DToValue() (printed to stdout) is 74.2 or something like that. If my mouse is exactly lined up with the tick mark ...

Hi, I'm playing around with JFreeChart v1.0.13 trying to see if I could possibly use NumberAxis as the axis of something other than a JFreeChart. I've setup a simple example and I'm noticing that when the I invert the axis with setInverted(true) the values I get from calls to java2DToValue() are sli...

Great. Thanks for the reply. I ended up doing something similar (but probably uglier) by extending the NumberAxis and overriding the refreshTicks() method to change the text of the ticks to what I wanted.

Hi, I have a XYPlot that uses the XYBlockRenderer to create an intensity chart. The X (domain) axis goes from 1 to 50. The default behavior of the Axis is of course to plot "1" at the leftmost extreme and "50" at the rightmost extreme of the axis. However for my particular application, I'd like to h...

Update: After some research my new plan is to attempt to create my own renderer. The renderer will create a buffered image from Java's WritableRaster class and paint the image on the chart. Java seems to be able to do this very quickly even for large data sets. I understand that this breaks JFreeCha...

I'm working with an XYPlot using an XYZDataSet and XYBlockRenderer to generate a surface plot (or contour chart, or intensity chart, we all seem to call them something different here). My XYZDataSet has one series that consists of about 118000 data points. The problem is that it takes about 10-15 se...

Checkout this topic which explains how to make custom legend labels. It worked for me =)

Sorry I'm a new forum user so it wouldn't let me post a link.

I am also interested in doing something like this. I'm trying to figure out the cleanest way to manually construct LegendItems and then create a new LegendTitle out of them. I'm getting confused because a LegendTitle only has one method that takes a LegendItem (createLegendItemBlock). Is this what I...
