As some sharp eyed users noticed yesterday, Google has now confirmed the roll-out of graphical time period segmentation.
A new drop down allows you to view AdWords data by day, week, month and quarter on the graph. The new feature makes it easy to view trends quickly and toggle back and forth by time period right from the drop down. So, if you’re looking at two years of data, you can opt to view longer-term trending by quarter, for example.
The feature is available in all AdWords accounts.
