Charts for little numbers

I was recently reading a presentation and came to the next slide and it had your standard bar chart. However, something seemed odd about the chart. It was tracking across the months on the x axis, six to be exact. However, the numbers for the y-axis were so low, we're talking six and under that the chart seemed overdone or even pointless. Are there cut off points or limits to bar charts and the type of content that should be presented? Would this have been better suited for another representation (pie chart, just numbers, a list?) Does presenting this information possibly detract from any amount of credibility because the numbers come across so low and unimportant? When I first saw it, I wasn't impressed but what if those numbers represent something major? In this instance a well designed table could have provide more impact. Maybe a graphical depiction of each month with the numbers inside.
