Chart - Data Labels

See small model workbook attached. It has two worksheets ... data and chart. On the chart, I would like to apply the actual percentage ( column D of the Data worksheet ) to each of the applicable bars. For example, apply the value of 139% to the purple 06-Nov bar in the chart. I've seen it done, just don't know how to do it ... something about putting values in data labels. Any guidance would be appreciated.
