The update also brings an improved user interface and more options for customizing the page. It’s now possible for each module to be moved, opened, closed or hidden completely so that users can view the stats that are most important to them.
The stats chart itself has also been changed from a line graph to a bar graph:
“During the redesign we went with bar charts because the end of one day and the beginning of another shouldn’t be connected. Each day starts at zero and we think bar charts work much better for this type of data. We hope you’ll agree once you get used to the change.”
The new changes will also eventually be available to users of the self-hosted Stats plugin.
