creating a date range instead of using date data values from datasource in charts

Currently, when creating a chart in Analysis for Office, the tool will always use the values of the date data retrieved from data source, instead of creating a date range.

When we manually remove the single quote(') from each cell of date column then the chart is showing date but it is not retained after save/reopen.

Please find the attached document for details and my requirement.

Is there any work around to fix this problem?

SAP recommendation is :

As a workaround, maybe you could use a

script/macro in Excel to run with the workbook and remove those

apostrophes. However, this will not prevent the data cells to be

retrieved with apostrophes again when reinserting/refreshing the data

source, as this is how AO manipulate the data cells.

As per SAP this is by design and submitted IDEA for this.

Appreciate your help.
