Formatting display of percentages on stacked bar charts and pie charts

I have a couple formatting questions. I have stacked bar graphs and pie charts that contain very small segments, and whenever the percentages corresponding to those segments are small, they don't show. Making the image bigger doesn't work. How can I force Spotfire to always show percentages on stacked bar graphs and pie charts (in other programs you would have a labeled line that points to the segment)?

Relatedly, I would like to display the stacked bar graph percentages on the side of the bar instead of inside it (just like you can display a pie chart label on the outside rather than inside). How can I do this? Any help would be greatly appreciated.
