Brian, Thank You for posting.
At this time, we are working on lots of UI improvements for WebBrain. We will bring back the clicks and opens graph in a future update of WebBrain.
For now, if you would like to see the graph for your Brain, log in then open a URL as follows:
Replace BRAIN_GUID with your brain's guid... The number of hours to graph and the width and height of the image can also be configured. To find your Brains GUID select "File > Utilities > Statistics", your Brain GUID will show to the right of the heading "Brain GUID".
Hope this helps.
