After reading a question about binned continuous x axis and stacked probability bars on y axis I am wondering whether this plot has a name. Here is an example:
What this plot shows: We see how the proportions of the categories Yes, Maybe and No change depending on the binned Predictor value. Here, I used random data, so not much interesting is going on, i.e. there is no clear trend in the plot. Also see here about plot and data generation.
