Only display whole numbers in bar chart graphs. We don't have half customers :)

I've recently made a handful of new reports/dashboards to track customers in different stage's. The bar charts are displaying 1.5, 2, 2.5 etc... which seems odd. We are tracking customers stage - so there should not be and half increments here. It looks as though it happens when the scale of the report is under ten. For the comparable reports that have a scale bigger than 10, the half increments vanish and whole numbers are used. For consistency sake looking at the reports, it would be AMAZING to just have everything in whole numbers!   Can you share a few examples of why someone would use half numbers in gainsight?  I'd love to hear a few ideas!
