A fixed scale coordinate system forces a specified ratio between the
physical representation of data units on the axes. The ratio represents the
number of units on the y-axis equivalent to one unit on the x-axis. The
default, ratio = 1
, ensures that one unit on the x-axis is the same
length as one unit on the y-axis. Ratios higher than one make units on the
y axis longer than units on the x-axis, and vice versa. This is similar to
MASS::eqscplot()
, but it works for all types of graphics.
