Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Loadĭim st As DateTime = New DateTime(2010, 6, 1)ĭim dict As Dictionary(Of DateTime, Long) = GetData(st, dys) Right now, the GetData() routine uses random numbers in reality you would use a database. Here's my code to fill the chart, in both VB and C#. But if X is "apples", "bananas", "oranges", "grapefruits", you don't want an unlabeled point between "apples" and "oranges". (If your X axis contains numbers, it's easy enough to infer the unlabeled points. When set to 1, it insures that every data point has a label. Useful tip: The "AxisX Interval" is important.
"Area3DStyle Enable3D" does pretty much what it sounds like. My chart contains separate series for "data" and "weekends". You might want to show several series and have them overlay each other (for example "Revenue", "Forecast" and "Expenses"). For a "Line" graph, a series would be one line. You'll see that the Chart control has a section called "Series". I've selected "StackedColumn", for reasons I will explain shortly.īelow is my finished ASPX markup code. There are a number of nice chart styles, as you can see:
(It's under "Data".) Drag it onto your form. Let's talk about how I did this.įirst, start a new ASP.Net web form.

In my last post, I talked about Scrum and "Burndown Charts".
Here's an example of a chart I created in ASP.NET with the new control. ) The native support in 4.0 is a big help for ASP.NET developers, because we no longer need to worry about getting permission to install a DLL in shared server environments. (A very similar control is available as a free download to work with Visual Studio 2008, but charting is now built into the 4.0 framework. One of the cool new features in Visual Studio 2010 is the Chart control.
