Hi all: I am trying to draw a horizontal line along the zero "Y axis" value but since zero isn't showing therefore the line is not drawn. If I set my intercept to 15 then it'll work but I dont want to hardcode it because the Y axis parameters could be different for another variable. I would like to alway set my hline along the zero as default. Thanks
p <- ggplot(mtcars, aes(x = wt, y=mpg)) + geom_point() p + geom_hline(intercept=0) Felipe D.
