Well I guess it depends what you mean by "whole family tree come up"
Im guessing maybe you mean the "pedigree view" with you as the home person.
You can get to that by going to familysearch (not community)
and clicking on Family Tree / Tree / making sure landscape is selected.
see the screen shot below
let us know if this is not what you are referring to.
There could be thousands of people in one's family tree - there is no way to put them all on the screen at the same time - but you can navigate the pedigree chart to see each family member.
