This example extends the Simple Area Chart example by decorating the chart using a number of chart formatting features.

• Create a XYChart object with background color and 3D border using XYChart.XYChart.
  
  
• Set the background, border and grid colors of the plot area using XYChart.setPlotArea.
  
  
• Add a title to the chart using BaseChart.addTitle. The title text is represented using CDML for including star icons in the text.
  
  
• Add titles to the axes using Axis.setTitle.
  
  
• Set the axis widths using Axis.setWidth.
  
  
• Use a semi-transparent gradient color as the area color. The gradient color is created using BaseChart.gradientColor.
  
  
• Add a logo at the bottom right corner of the plot area as custom text using BaseChart.addText with BottomRight alignment. The logo includes images and text encoded using CDML.
