I don't think you'd be able to use a background image to show the movement across time.
Do you have the data for the weather movement? You'll need to have spatial data against time to get this kind of view. Similar to what my colleague has here: Tableau Public
Thanks Mavis for replying - greatly appreciated Yes, the end goal would be to have the Tableau map appear like the gif that is moving in that pic & not to use a background image. Was thinking if I could find the data set that is feeding this http://images.intellicast.com/WxImages/RadarLoop/usa_None_anim.gif then we could put the update date timestamp on the shelf and let it play / loop once published. Just not sure how to get current US precipitation data and graph like the gif. Thanks agan for your reply - Best, Matt
