Do you really need to erase everything?
IDL> p = plot(findgen(100))
IDL> p->setData, (findgen(100)^2)/1000.0
Or if you want to change a bunch of stuff at once:
IDL> p = plot(findgen(100))
IDL> p->refresh, /disable
IDL> p->setData, (findgen(100)^2)/1000.0
IDL> p.title = 'New title'
; ... set more properties ...
IDL> p->refresh
