At the moment it seems to show you the full legend... which if you have a lot of items can be confusing.
Is there a way to show the specific legend for the line that you hover over on the timeline graph.
Which timeline visual did you use? Please provide more information to reproduce your problem. If possible, please post a screenshot.
I tested with the custom visual "as Timeline", didn't encounter your problem.
The issue occured with the standard timeline graph. The way round it I found was to put the field in tooltips and set it to 'FIRST'.
I would have thought though that the standard tool tip when hovering over a line would just that line.
