SUMMARY
The Microsoft Office Chart Web Component can be used to create a chart using data from different sources, such as arrays, spreadsheets, and databases. This article describes how to use data in a Spreadsheet Web component to create a chart. When a chart is bound to spreadsheet data, changes made to the spreadsheet data are reflected in the chart.
MORE INFORMATION
To connect a chart to spreadsheet data, you can set the Datasource property of the Chartspace object to the Spreadsheet component that contains the data. The example below describes how to bind a spreadsheet control to a chart using VBScript:

Sample Code
