Symptom:
When the visualization with horizontal bar graph size is small, the data value of the biggest bar would not be visible.
Steps to reproduce in Tutorial Project:

Default setting with 'Hide Overlapping labels ' checked: The value can only be shown when given more space for the visualization.
Uncheck "Hide Overlapping labels ": The value would be truncated at the border so the whole number is not visible as shown below:

CAUSE:
This is a known issue in Strategy Web 10.x and it is being investigated.
