I have data that describes the number of files collected per type per device.  I'd like to display this data as a histogram of file counts per device, where each bin contains two side-by-side bars, one per file type.  I've gotten most of this done, but the bars are overlapping and I can't get them display next to each other (can't stack them either, because then the total height of the bar will be meaningless due to double-counting of devices).  Please see the attached workbook for details.  The original data is not pivoted (i.e. counts per type are columns, not rows), but I used Tableau's pivot function to unpivot them.
