Can anyone suggest me how to change the text "Unknown Chart Type" which appears on an extension object when not in webview?
my guess is you cannot I am afraid...
you can go to the sheet properties (where there is your extension object) and go to properties of the uknown chart. Then you can go to Error Message (general tab), click on "All expressions disable" and write your text.
Thanks Elena. Its really working.
