I am trying to use 
plot datafile with ellipses 

major and minor axes are in x-units or y-units (depending on 
set style ellipses settings).  But I don't know what the units are (or even mean)
and the coordinates of my plotted ellipse depend (for instance) on xrange and 
yrange.  I know the absolute coordinates and that's what I want.  
Help please!   For instance I want to plot an ellipse, center at origin
major axis 10, minor 2 and major aligned with y-axis.  
datafile is:
0 0 10 2 90   
But this doesn't work as I alter yrange.
