This example demonstrates the following basic steps in creating a bar chart:

• Create a XYChart object using XYChart.XYChart.
  
  
• Specify the plot area of the chart using XYChart.setPlotArea. The plot area is the rectangle bounded by the x and y axes. You should leave some margin on the outside of the plot area for axis labels, chart titles, etc.
  
  
• Specify the labels on the x-axis using Axis.setLabels.
  
  
• Add a bar layer and specify the data for the bars using XYChart.addBarLayer.
  
  
• Generate the chart using BaseChart.makeChart2.
