Formatting Shown Values on Charts

[JBCLARK20]

I have a stacked bar chart and want to show the values in the bars. Picking show values from the drop down makes them appear. Only problem is that there does not seem to be a way to control if the value appears at the top,bottom or middle of the bar or what to do when the value size is larger than the hieght of the portion of the stacked bar. Also there does not appear to be a way to format the font appears on the value. Am I missing something or is this kind of chart control completely missing from Cognos 10.2.1?
