Currently when hovering the cursor over the User Conversion chart, a tooltip box shows number of Views, Downloads, Prints, and Followers, as shown on the screenshot below.
Please add conversion rates for downloads and prints to the tootip box. The rates can be shown inside parentheses to the right of their respective numerators, ie, Downloads and Prints.
P.S. : A related feature request on the User Conversion chart was proposed here a few days ago
