Charts are OLE objects. Use the Basic macro below (you might need to fix 
unwanted line breaks) and the Basic IDE to examine the Chart-object. In 
the column Type in the watch-window and in the variable 
"SupportedServiceNames" you will find the hints, which part of the API 
is relevant. The variable "Types" contains information about the 
supported methods. Or use Xray (in Basic) to examine the objects to 
learn the supported methods.

You can start examine the objects, if you set a break point at the line 
"msgbox" inside the for-loop and add the objects to the Watch-window.

Kind regards
