Can bars render overlapped in Chart JS?

I'm trying to create a bar chart that shows Minimum, Average, and Maximum values. I have the the three bars showing next to each other, but I'd like to overlap them so it looks like a stacked bar chart. The stacked bar chart doesn't work for this because it sums the values of each series and this is not appropriate for min, avg, and max values.

Could you not just create different values for the series? If I have a min of 3 and an average of 7 and a max of 10 the series would be 3, 4 and 3. That is simple math you could model in the microflow creating the serie.
