csDrawGraph

This COM object / ASP component draws pie and bar charts and line graphs on the fly. Output can be streamed to the browser using BinaryWrite, or saved to file. Image types include GIF, PNG, JPG and bitmap. 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. Show percentages or actual values. Generate the colours at random if prefered. Bar charts have a choice of orientation - vertical or horizontal, and a stacked bar chart option is available. Trend lines can be shown on bar charts as well as additional plotted lines. Bar charts and line graphs can auto calibrate the axes. All the graphs can show legends. Additional text can be added to annotate the graph. Text supports Unicode characters. HTML image maps can be produced. Free trial available with full instructions.
