Attach a numeric label on each bar? |

How high up should we go with the bars? |
Distribution of Audience vs. Distribution of Impressions
By default, this chart shows how many people in the target are at each level of exposure. You can quickly see how big a group saw your ad once, twice, and so on. This is a very traditional way of looking at a frequency distribution. It's also the most practical for understanding the breakout of your target, who has not yet been well-reached, who is getting there, who is at some notion of an effective level, and perhaps who has gone beyond into some wearout level of exposure.
Some people looking at a chart like this initially may be disturbed by the very first bar at level 1. "Gee, that seems like a lot of people I'm paying for who aren't really being exposed properly." If that concern is raised, showing the frequency distribution by impressions may be helpful:
