daress,

I agree that NormalProbabilityAxis would be a better name. I have not made an axis for any other distributions. I mostly use log-normal distributions in my work. Please feel free to add another axis type.

Nice to see it was useful for someone.

Thanx,

John

I had a bug in the previous submittal. If you zoomed out and then back in around the 0.1 or 99.9 tick marks on the axis, the tick marks were not always in the correct position, and you could get 0 or 100 for the tick mark, etc. I have this fixed now. I also fixed the setPrecision() method so that it...

I have fixed the axis so that at least one labeled tick mark will show on zoom in. I've limited the minimum axis range length to 0.1, and the smallest tick mark step size to 0.01. This is due to the accuracy of the approximations for calculating the cumulative normal function and inverse cumulative ...

David,

I hadn't even considered that. I think I see a way to fix it so that tick marks show on zoom in, but I won't be able to work on it for a few weeks. I'll submit a new version around April 15.

Made some minor changes, basically taking our some magic numbers, and making it easier to change the number of random draws. This code is free, open, and submitted for use by the JFreeChart project.

Made a few minor changes to the demo. It is now easy to change the number of draws. Also, now calculate the cumulative percent, rather than using a value from a table. Basically, took out some magic numbers. This code is free, and submitted for the JFreeChart project use. John /* -------------------...

I want to have two or more sets of data in my ScatterPlot. How should I do, is it possible? The following code I use at the moment, because the ScatterPlot require the type XYDataset, but it is only one set of data. I can not find data.add() or something like this.... please help me /Mike XYDataset...

Hello John, Thx for the code...this would be helpful... could you please tell me that which 'change' code you are talking abt? and this code would be added in the last so that it would print current points ? i am new to it so can you tell me in brief how to start with it? Anamika Sorry I wasn't cle...

I had a similar problem getting the coordinates to show on a plot for a mouse click. I solved the problem by including the "change" code in an invokeLater() block. Maybe the following code fragment will help: javax.swing.SwingUtilities.invokeLater(new Runnable() { public void run() { plot.clearAnnot...
