JFreeChart

JFreeChart can be used to create a wide variety of charts. Have a look at the site's samples.

My Examples

Click on a chart image to load a bigger version:

• LineChartEx.java: uses data stored in categories;    
   
  
• XYLineChartEx.java: uses (x,y) data; modified colors and grid lines    
   
  
• XYLogAxisEx.java: (x,y) data displayed using a log-scaled y-axis    
   
  
• XYPlotEx.java: the data is read from men.txt and women.txt; the chart is saved as a PNG file    
   
  
• PlotFunctionEx.java: the (x,y) data is generated from a PolynomialFunction2D object; clicking on the panel or data points prints coordinates    
   
  
• TimeSeriesChartExample.java: two lines of time data are displayed;    
   
  
• DynamicTimeSeries.java: time data is generated at runtime using a Timer object    
   
  
• DualAxisDemo.java: the two lines use different y-axes; the data points are visible    
   
  
• ScatterPlotExample.java: (x,y) data shown as points; the axes are drawn; the data points are changed to red crosses   
   
  
• BarChartEx1.java: data stored in categories;    
   
  
• BarChartEx2.java: horizontal bars; solid color bars; x-axis moved; data built using DatasetUtils    
   
  
• StackedBarChartExample.java: data stacked in bars; bar color, margin, and spacing changes; simplified legend    
   
  
• OverlaidBarChartDemo.java: a bar chart with a line chart on top; both use the same x-axis categories; rendering changes made to both charts    
   
  
• StatisticalBarChartDemo.java: data includes means and standard deviations; margin changes    
   
  
• HistogramEx.java: data is organized into bins and counted    
   
  
• PieChartExample.java: labels reformatted; simplified pie coloring    
   
  
• AreaChartDemo.java: transparent areas; grid lines; margin changes; simplified tick units; data built using DatasetUtils    
   
  
• StackedAreaChartDemo.java: same as Area Chart example, but data is now stacked    
   
  
• BubbleChartExample.java: (x,y,z) data drawn as bubbles -- the z- value becomes the bubble size; x- any y- axis ranges are adjusted    
   
  
• PolarChartExample.java: three lines of (angle, radius) polar data; rotated radius axis labels
