This ASP.NET component draws pie and bar charts and line graphs "on the fly". Graphs can be streamed to the browser as GIF or JPG images or saved to file. A wide range of properties allow the customisation of colour, size and text style. Built in defaults allow the production of graphs with only a few lines of code. Use random colours if prefered. Produce HTML image maps for the charts. Can also be used with Windows Forms. Free trial available.
