When creating bar/column and pie charts, I would like to have the option to draw the exact values of the data being represented on the chart so that each bar/column would have a number printed either at the top or in the middle of the bar. I was hoping to see this as an option under chart elements. In the case of bar and column charts, I would like to have the option of having the values displayed in the middle or at the top of each bar/column.
Select the series in the chart, to which you want data labels. You can use the drop-down list for that. Then menu Insert > Data Labels. The default setting is to use the number format of the table. But you can uncheck that and set an own number format with the desired accuracy.
