Create expressive 2D and 3D charts within your spreadsheets. Chart types include Column, Line, Pie, Bar, Area, XY, Bubble, Stock, XYZ, Doughnut, Radar and Polar. Add charts through code by using the comprehensive chart object model, or at design time by accessing the Spread Designer and Chart Designer. Charts can be bound to external data sources, and you can allow end users to make changes to chart formatting at run time. The fully integrated support for charts in Spread features built-in design dialogs that you can make available in your applications to allow your end-users to create and modify charts in Spread just as they do in Microsoft Excel.
