why doesn't my chart update?

I can't work out why my chart doesn't update when I change selection.

Here's my code so far on Plunker

The code that seemingly doesn't work is:

dropDown.on("change", function() {
    d3.selectAll("circle")
      .data(orgData[this.value])
      .attr("y", function(d) {
        return height - price_scale(d.value);
      })
      .attr("height", function(d) {
        return price_scale(d.value);
    });
  });

The code comes from the answer to a previous query that I made:

How to use d3 filter and update function to toggle between data selections

That code worked because the update function tweaked the parameters of a circle svg object. Is there a parameter I've not factored in with rect objects?

circle elements don't have height or y attributes, they have cx, cy and r attributes.

Alternatively maybe you meant to select rect elements which do have height and y attributes.
