Aesthetic mapping: engine size mapped to x position, fuel economy to y position. Replicable code is below. Even with coord_cartesian, you can still use scale_x_continuous to set the breaks, but coord_cartesian will override any effect of scale_x_continuous on how the data are plotted. Pay attention to the structure of this function call: data and aesthetic mappings are supplied in ggplot(), then layers are added on with +. For geom_bar the default stat is bin, thus it must be changed to identity as Justin showed. geom_bar() makes the height of the bar proportional to the number of cases in each group (or if the weight aesthetic is supplied, the sum of the weights).
