I have been using the Balamurugan Line Graph and Pie Chart scripts with good results. Just wondering if anyone has enhanced them or can recommend other scripts. Specifically I am looking for:
- more flexibility in width and descriptions in X axis.
- control of incements in Y axis.
- multiple variables in the Y axis
- choice of colors and layout
