Displaying a Chart in ASP.NET

Hi All,

Sorry to bother you all again, but I seem to be having a hard time learning asp.net. I get close but at times not close enough.

I have a chart that is displayed in the same window in internet explorer and I would like to make it seperate or a pop-up that can be closed without lossing my main web site page. If I hit the back arrow it won't go back to the main web site, it just keeps displaying the chart. 1 'draw and display the chart.

3 Dim i As Integer = 0
4 Dim xPos As Integer() = {52, 144, 236}
5 Dim yPos As Integer() = {40, 80, 220}
6 Dim xSize As Integer() = {40, 40, 40}
7 Dim ySize As Integer() = {200, 160, 20}
