While participating in another discussion about colorizing the Visits Diff pepper, I took a close look at my installation this morning and noticed that it didn’t make any sense (at least to me).
Here are some numbers extracted from my Visits Pane this morning:
Past Month Unique
This Week 16,804
Last Week 88,198
2 weeks ago 91,588
3 weeks ago 89,922
4 weeks ago 88,134
Not much of a change from week to week. This week is low because it’s only 36 hours into the week.
But the Visits Diff graph seems to tell a completely different story. It is set to show Past Month and Unique Visitors. It shows 5 horizontal lines, the center line being 0 and the increments for the other lines being 5k and 10k (at plus above the zero line and at minus below the zero line).
For the 4 weeks ago column, it shows a positive bar at +4k, for 3 weeks ago a positive bar at +2k, for 2 weeks ago a negative bar at -10k and for last week a negative bar at -11k. This week shows a negligible -.5k bar. Either my basic math skills are lacking or I don’t understand how the graph works. Shouldn’t the differences be only 2k to 4k from week to week, based on the main Visits Pane numbers?
