From my experience with Gtk2 (upon which Wx can be built on some systems), svg will be very slow. However, if you use one of the modern canvas type widgets, ( I don't know Wx), like the Gnome2::Canvas or the Goo::Canvas, you can do pixel zooming quite easily. See

Goo::Canvas Graphing demo

Gnome2::Canvas Scribble with Image and

Tk Realtime data aquisition for some non-Wx graphing ideas, that you may use with Wx.
