12.37: The `
|
`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 latitude.
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 north-south and east-west
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
north-south and east-west directions.
