GreenCan and I are proud to present our Excel Chart UDF. The UDF is written for and tested with Microsoft Excel 2007 and Excel 2010. The example scripts won't run with older versions whereas the functions don't check the Excel version - you use them at your own risk. The UDF consists of one function to create a simple chart (you just have to specify the data area, the type of graph to draw, title, position of the chart etc.) and a lot of functions to create/modify all aspects of the chart.
