Well...that's just as doable. Now that I actually tried to run zplot,
just change the PLOT command to a command to recalculate the axis and
plot, e.g. (where oxrange is the default xrange which gets re-used for a single
click with no drag along the x axis., and position is the position
keyword in xplot)

if(xr[0] eq xr[1]) then xr=info.oxrange

xs2=Normalize(xr, Position=[info.position[0], info.position[2]])
info.thisPlot->setproperty, xrange=xr, xcoord_conv=xs2
info.xAxis1->setproperty,range=xr,/exact, xcoord_conv=xs2
info.thisWindow->Draw, info.plotView

;;
You'd also need recompute=2 on the XTICK text object to make the font
stay pretty. It works like zplot, without the overlay graphics during the
drag phase..

It also needs some code to stop you zooming in too far, like zplot,
the axis drawing breaks down after a while.
