The Microsoft Chart controls make it easy to take data – such as sales numbers, website traffic statistics, and so on – and turn it into a chart, which can be saved to an image file or displayed from a web page. In Plotting Chart Data we examined a myriad of ways to turn data into a chart, including: plotting the chart data point by point; binding data to the Chart’s Points collection; programmatically binding data structured data to the chart; and declaratively binding data using one of ASP.NET’s data source controls, such as the SqlDataSource or ObjectDataSource. Oftentimes, web pages that display charts include user interface elements that let the user filter or sort the plotted data. For example, when viewing a chart of expenses, the user may want to only show expenses between two dates, or may want to sort the expenses by category. One way to provide such functionality is to sort or filter the data before binding it to the chart. Alternatively, you can bind the original data to the chart and then instruct the Chart control to sort the data, or to apply a filter. This article shows how to use these sorting and filtering capabilities. Read on to learn more! Read More >
