9.3.37: `resize'

`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 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.
