This example extends the Icon Pie Chart example to demonstrate using CDML to include icons and multiple fonts in chart title, sector labels and to draw logo.

• The title containing multiple fonts and colors is written in CDML and added to the chart using BaseChart.addTitle.
  
  
• The logo designed using CDML is added to the chart as another title using BaseChart.addTitle2 with BottomRight alignment.
  
  
• The icons file names for sector labels are added to the chart as an extra field using PieChart.addExtraField.
  
  
• The sector label format is designed to include the icon using CDML and parameter substitution. It is then set into the pie chart using PieChart.setLabelFormat.
  
  
• The search path to load the icon images is configured to be the same as the script directory using BaseChart.setSearchPath. This is needed in IIS because the current directory in IIS is the directory of the IIS executable, not the script directory.
