I guess the sources are very old and doon't work with the latest version.

To "start" JFreeChart follow this link
http://www.jfree.org/jfreechart/jfreech ... -demo.jnlp

Fine,
how can I make my Line Chart? Its only a demo. If I try to do my Chart with the original jfreechart-1.0.1.zip, I become every time a lot of error messages.

How can I start this Demo from my Computer. How can I compilie the source on my computer. I become only error from the javac.exe. Is same the alpha software

?

1) Before starting with JFreeChart make sure you know about Java
2) Use an IDE, this will prevent you from many compiler/classpath problems.
3) Buy the developers guide or search the forum for your problem.

Some sources are created with older version as 0.9.
You have to modify some imports.

For example, replace :

Code: Select all

import org.jfree.data.DefaultCategoryDataset;
import org.jfree.chart.renderer.BarRenderer;

by :

Code: Select all

import org.jfree.data.category.DefaultCategoryDataset;
import org.jfree.chart.renderer.category.BarRenderer;

For sure, it's more easy to correct this with an IDE.
