Users 1 and 15's charts make no sense - they have to be special system accounts of some sort. My guess is that #15 is the account that receives trading fees, and #1 represents MtGox itself (or some specific aspect of MtGox, such as its cold-storage). There're still a lot of points on these plots that don't make sense, though; generally they look like vertical stripes labelled as sets of small sell orders, both far be…
Each dot is a trade. I pulled the columns from the db we generated with the raw info of that one big trade, so you can see what the structure of the source data looks like. Removed the user id of the buyer, but it's trivial to find if you have the dataset.

Re: The MtGox 500
#41So the size of the dots are the Money_JPY "volume" - that is, Yen, and not Bitcoins? Isn't that a bit redundant, because it contains information from the y-axis, which encodes the Yen value of a BC? Wouldn't it have been more interesting to see if the number of BCs traded actually went down with the increase of value of BCs? Right now, it only shows how the volume of trades has increased, but that seems to be obvious given BC's value hike. Actually, to make the graphs distinct, shouldn't the number of BCs traded be on the Y-axis (maybe on log scale, too, as I suspect a huge drop over time) and the dots remain as they are?
