    ! We bin the d1 and d2 datasets into d3 and d4. The parameters for binning
    ! are chosen so that the bin midpoints will be the integers from 0 to 15.

    let d3 = hist d1 from -0.5 to 15.5 bins 16
    let d4 = hist d2 from -0.5 to 15.5 bins 16

    ! Because we want stacked dotplots, we must cumulate d3 and d4 before
    ! plotting d4 above ("from") d3.

    let d4 = d3+d4

    draw dotplot d3 indianred
