`resize {x for maps}{y for maps}' 
Resize the axes frame region in such a way that geographical objects appear in correct proportions. This assumes that y is degrees latitude and x is degrees longitude.
resize x for maps
'
Resize the plot width for maps, assuming that x represents longitude and
y represents latitude. Before using this, you must have defined scales
for both x and y, and a size for y (ie, you must have done
`set x axis ...
', `set y axis ...
' and `set y size
');
this command
sets the x size, thus eliminating `set x size.
' The result is that,
at the central latitude (y), a centimetre on the page will correspond to
an equal distance on the earth, in both the northsouth and eastwest
directions.
resize y for maps
'
Resize the plot height for maps, assuming that x represents longitude
and y represents latitude. Before using this, you must have defined
scales for both x and y, and a size for x (ie, you must have done
`set x axis ...
', `set y axis ...
' and `set x size
');
this command sets the y size, thus eliminating `set y size.
' The
result is that, at the central latitude (y), a centimetre on the page
will correspond to an equal distance on the earth, in both the
northsouth and eastwest directions.
