I’ve been doodling some chart in R/ggplot using geom_text() to generate a labelled scatterplot.
The chart actually builds up several layers using different datasets, so it’s not obvious how to set the ranges cleanly: I know the lower bound I want for the y-axis (y=0), but I want to let the upper bound float.
There’s also an issue with the labels overflowing the edges left and right.
So here are a couple of lines to make everything better (chart is in g):
#Find the current ymax value for upper bound #(via http://stackoverflow.com/questions/7705345/how-can-i-extract-plot-axes-ranges-for-a-ggplot2-object#comment24184444_8167461 ) gy=ggplot_build(g)$panel$ranges[[1]]$y.range[2] g=g+ylim(0,gy) #Handle the overflow by expanding the x-axis g=g+scale_x_continuous(expand=c(0.1,0))
