Cartesian coordinates with fixed relationship between x and y scales.

Usage

coord_fixed(ratio = 1, xlim = NULL, ylim = NULL, wise = NULL)

Arguments

ratio
aspect ratio, expressed as y / x
xlim
limits for the x axis
ylim
limits for the y axis
wise
deprecated in 0.9.1

Description

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 eqscplot, but it works for all types of graphics.

Examples

# ensures that the ranges of axes are equal to the specified ratio by # adjusting the plot aspect ratio qplot(mpg, wt, data = mtcars) + coord_fixed(ratio = 1)

qplot(mpg, wt, data = mtcars) + coord_fixed(ratio = 5)

qplot(mpg, wt, data = mtcars) + coord_fixed(ratio = 1/5)

# Resize the plot to see that the specified aspect ratio is maintained
