Remarks
This method returns only one chart. If multiple charts with the same name exist in the workbook, then the first of those charts (as determined by Excel Services) is returned.
This method returns an error if the requested chart or PivotChart does not exist or is not published. The returned URL is valid for the duration of the session. If the chart image has been purged from the cache and the previously generated URL is requested (that is, the URL generated in the same session), the chart image will be recreated and returned.
