So my advisor pointed out this ‘new’ (well, 2004), way of plotting results of logistic regression results. The idea was presented in a 2004 Bulletin of the Ecological Society of America issue (here).

Here’s the code:
Here’s a few examples using datasets provided with the ggplot2 package:
And two examples of the logpointplot function:
