Change Chart Type Dialog
The Change Chart Type dialog allows end-users to change the type of an existing chart to give it a different look. The dialog box contains a list of all available chart types and subtypes.
Create the Type group within the Ribbon UI's Chart Tools | Design tab to provide end-users with the capability to invoke the Change Chart Type dialog. Refer to the Lesson 1 - Create a Simple Spreadsheet tutorial to learn how to create a spreadsheet application with the Ribbon UI.
End-users can also invoke the Change Chart Type dialog by right-clicking the existing chart and selecting the Change Chart Type... item in the context menu.
