This function is a thin wrapper around geom_blank() that makes it easy to add such values.
Key function expand_limits(). Can be used to : quickly set the intercept of x and y axes at (0,0) expand the limits of x and y axes # set the intercept of x and y axis at (0,0) p + expand_limits(x = 0, y = 0) # change the axis limits p + expand_limits(x=c(0,30), y=c(0, 150)), R expand_limits Sometimes you may want to ensure limits include a single value, for all panels or all plots. This function is a thin wrapper around geom_blank() that makes it easy to add such values.
expand_limits adds a dummy layer with data to stretch the axes, so you cannot undo that easily. Three options come to mind: don’t use expand_limits in plotSmth, maybe xlim()/ylim() would do the job instead, and those can be reset force the limits with e.g. coord_cartesian() remove the dummy layer.
expand_limits and scale_y_continuous. Another option is to use expand_limits() to force each panel to start at the origin and then use scale_y_continuous(expand=c(0,0)) to remove any extra space on around the y-axis limits. The two values in expand are c(multiplier buffer, additive buffer).
7/19/2019 · To force the origin to start at zero, you can use the exapnd_limits function with scale_x_continuous, and scale_y_continuous as follows: library ( ggplot2 ) df ggplot (df, aes (x, y)) + geom_point () p y = 0) +theme_bw (), # Change the y-range to go from 0 to the maximum value in the total_bill column, # and change axis labels ggplot (data = dat, aes (x = time, y = total_bill, group = 1)) + geom_line + geom_point + expand_limits ( y = 0) + xlab (Time of day) + ylab (Total bill) + ggtitle (Average bill for 2 people)
