I have discussed about WebChart Control for ASP.NET and ZedGraph in my previous article ASP.NET Free Chart Control and Class Library – Part 1. Now when I have played with both of them for one week I am able to declare the winner and it is…
… Zedgraph all the way. First I have given try to WebChartControl because it looks easier to work with as seen in the tutorials. Indeed it is easy but there is little left to customize it. It is good only for creating very simple charts. Then I have tried Zedgraph, although at first it seems not so easy to develop charts with it but there is very good documentation available for it as I have discussed in my previous article. The wiki has very nice tutorial for creating line charts, bar charts, pie charts etc. I have created very complex charts with it and day by day I am exploring it more because it has a lot of depth. So I will suggest to use Zedgraph for including charts in your asp.net applications for free.
It is available for download at http://sourceforge.net/projects/zedgraph/ .
