In general, you can determine the width of a box plot in ggplot like so:

ggplot(data= df, aes(x = `some x`, y = `some y`)) + geom_boxplot(width = `some witdth`)

In your case, you might consider setting the width of all the box plots to the range of x divided by the maximum number of elements (in the leftmost figure).
