Powerpoint Macro to add Labels to all Bar Graph Charts

  • Good morning. I have a powerpoint presentation with about 30 bar graph charts. I am now being told after the fact that all of the bars should have labels (percentages, no decimal points). Because each chart has about 7 series, it would take me a tremendous amount of time to manually add labels to each bar. Is there a quick macro that anyone could write to label all of the bars?

    Thank you so much in advance.
