One possible work-around would be to increase the amount of available space for the report tile. This can be done by following these steps:
1. Switch to the "Summary Report" tab
2. Click the File > Page Setup... menu item
3. Increase the available space by either increasing the page width or changing the page orientation from portrait to landscape
The screenshot below shows the before/after of an example report tile.
Thanks for the thorough and quick reply. I discovered this and was able to display the smallest two or three - bought me some time.
Unfortunately it doesn't allow the last label to display where a response was merely "1". It's as if the chart "knows" it will look bad... but you know how clients are - they want what they want!
