Dynamic histogram charts

I would love to see interactive histogram charts. Ideally I would pass a single series of data to the chart, along with a default number of bins. Then the user would be able to change the number of bins and the data would be re-binned and the chart re-drawn. Bin labels would be need to be regenerated automatically as well, either from the range of each bin, or its center-point.

An example:

Series: { data: [1,2,1,2,1,2,3,3,4,4,4,4,4] }
Histogram: { defaultBins: 2}

would become:

xAxis: { Categories: [ "1-2", "3-4"] }
Series: { Date: [6, 7]}

Then if the user changed number of bins to 4 (via a slider or text entry), the data would be rebinned as:

xAxis: { Categories: [ "1", "2", "3", "4"] }
Series: { Date: [3,3,2,5]}

and the chart redrawn.

This feature would be especially useful in scientific applications, where histograms are frequently used.
