ComponentOne WebChart Blows!!!
I didn't realize how badly it blew until I attempted to do something for a client with it. They own the product and asked me to work on a few charts for them. The documentation is non-existent. Their product pages on the web site claims it does things that the object model clearly doesn't support. I wasted three hours of my life attempting to create a simple column chart that could be done in 2 minutes in Excel. I still don't have a column chart!
I could have written the C# code to draw the image using GDI+ faster than trying to figure out how to use this piece of junk!
