The Performance by Region Widget allows you to see in real-time the top 50 regions across the world visitors are hitting your site from, and how the site is performing by region.
The widget is a bar graph and the data is laid out such that each region has an average performance number (over the Dashboard Time Period) listed for each of the available metrics. The default view shows average Onload.
To hide or show different metrics, click the legend items at the bottom of the widget. They will appear as additional bars in the graph. Note the more metrics you turn on it becomes a little more difficult to read as the space quickly becomes filled with new bars and the text becomes smaller.
Also, the regions are ordered by traffic, so those with the most traffic to your site show at the top.
