WebGrid Community Server

I am using WebGrid Chart control and I am not getting the graph when I run the code (in debug mode).
I am using Visual Studio 2005 on XP Prof. SP3 machine with IE 7.
Here's the code I am using:

ArrayList tmp = new ArrayList();

Random random = new Random();

tmp.Add(new WebGrid.Util.ChartValue("Sample 1", random.Next(1, 100)));

tmp.Add(new WebGrid.Util.ChartValue("Sample 2", random.Next(1, 100)));

tmp.Add(new WebGrid.Util.ChartValue("Sample 3", random.Next(1, 100)));

tmp.Add(new WebGrid.Util.ChartValue("Sample 4", random.Next(1, 100)));

tmp.Add(new WebGrid.Util.ChartValue("Sample 5", random.Next(1, 100)));

Never mind folks found my problem!

I forgot to define the ChartType :)

ccDaysByDept2.ChartType = WebGrid.Enums.ChartTypes.VerticalBarChart;
