The Microsoft Chart controls are a series of classes in the System.Web.UI.DataVisualization.Charting namespace that allow web
developers to ability to add charts to their ASP.NET applications. The most pertinent charting-related class is the Chart class,
which contains information about the chart’s appearance, series, charting areas, and so forth. In most of the demos and code
samples we’ve explored thus far, we’ve used the Chart class as a Web control, adding the
ASP.NET page, setting a few properties and, occasionally, writing a few lines of code. When used as a Web control, the Chart class
both creates the chart (as an image) and then renders an element that points to the generated chart image.
Using the Chart Web control is a standard practice in a WebForms application, but it is not suggested when building an ASP.NET MVC
application. (While it is possible to add Web controls – including the Chat Web control – to the views of an ASP.NET MVC
application, it is generally frowned upon.) So, if we can’t use the Chart Web control in an ASP.NET MVC application, how do we
display a chart? In addition to being used as a Web control, the Chart class can also be used programmatically. It is quite
possible to create a new Chart object, set some properties, plot the data points, and then generate the chart image. In fact, we
looked at using this technique in an earlier installment, Programmatically Generating Chart Images, in which we saw (among other
things) how to generate chart images programmatically and add them as attachments in an email message.
