When I try to plot an Histogram or a 3d Pie Chart I get the following Exception:
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/log4j/Logger at org.jfree.chart.plot.PiePlot.<clinit>(PiePlot.java:309)
at org.jfree.chart.ChartFactory.createPieChart3D(ChartFactory.java:287)
at Pie3DChart.crearGrafica(Pie3DChart.java:93)
at Pie3DChart.main(Pie3DChart.java:138)
I also tried to compile the source code but I get the following Exception:
JFreeChart.java:129: package org.apache.log4j does not exist
import org.apache.log4j.Logger;
^
JFreeChart.java:235: cannot resolve symbol
