CTRL+drag the measure from Columns to Label. You still want the measure to be on Columns as well, this will remain actual values (while the labels will be %).
Click its right arrow box on the measure on the Label shelf and choose Quick Table Calculation > % of Total.
Choose Compute Using > Table Across. Then format as desired.
Hope this helps,
Thank you so much, but the item are in measure values. so there no no "quick table calculation" when right clicking. Is threre still any other way?
Please share the sample workbook, it will be helpful to check and revert.
