Currently there is no ability to control where data labels are placed on a graph. Could you please add this functionality similar to Excel where the report designer can control the placement of data ...
The ability to adjust and show labels directly on the chart instead of a legend also follows the best pratices of accessibilty and visualization comprehension. A good example of this is in Esri's ArcGIS products which have the ability to set what is most important in labeling while still having the labels be dynamically placed.
