want to make a distribution graph~~~

[Alex cordes]

just wonder is there any way to make a distribution graph of a data?
just searched for it on the net, cant get a code or example... ...
anyone know how to make it?
many thanks~~~

First, I recommend converting the data to some simplistic format like XML so it can be made uniform and easy to read. For Java graphing, there's a ton of SourceForge projects as well as proprietary chart programs, and some are better than others.

The reason I recommend the XML is that at least if you pick a particular format you can more easily migrating it to something else later.

Alex,

Firstly, if you want to make a graph you can use Java2D, I'm sure if you search around you will be able to find a basic tutorial to get you started.

If you want to put data ina table take a look at javax.swing.JTable. You can construct one of those by passing in two arrays for example

JTable myTable = new JTable(data, columnNames);  

where data is a two dimensional array of your data values (like a grid of rows and columns), and columnNames is a 1 dimension array of column names.
