More TokyoPop & Viz Charts

Following up on my post from earlier today about the volume number counts for TokyoPop & Viz:

I ran the numbers from the August & July Previews as well. Here are the histograms (you may need to click to see the larger version to read them fully):

TokyoPop:



Viz:



Series 1 (blue) = September
Series 2 (red) = August
Series 3 (yellow) = July

For TokyoPop:
September: Count: 39; Median: 3
August: Count: 42; Median: 2
July: Count: 39; Median: 3

For Viz:
September: Count: 38; Median: 8.5
August: Count: 31; Median: 9
July: Count: 35; Median: 9

(Note: for both publishers, I did not count books/novels, just manga volumes.)

With three months of data, it looks like the pattern is holding; TokyoPop produces more manga with low volume numbers, and more new titles each month than Viz.
