In general it would be nice to have more / more flexible options to position/size/layout datapoints, values, legends and so on but I'm not sure if it would be very helpful to show really each value of a chart and especially by a stacked bar-chart because it's in general rather difficult to read.
I know it's often a requirement from the users but if you couldn't understand the meaning behind the bars with one (or maybe a few ones) glance else you need to have a more intense view and reading all the values to comprehend the data it's IMO the wrong visualization and you need a different chart or maybe a table for it.
An alternatively might be to use several objects which are placed beside and/or overlapping each other (it's quite easy in View but in Sense rather not) to create a customized and sensible visualization. The following posting isn't directly related to your question but the idea behind it might be helpful for you: Use of a Silent Legend.
