Hi Guys,
I've taken the Total QBR Stats (ESPN) for all QB's from 2006-2014 and put them into Plotly to produce some modifiable graphs.
Because there are over 80's QB's with data I've hidden a lot the data/QB's because it becomes unreadable. However, if you click on their names on the Legend you can Show/Hide them but not all the available QB's show up on the legend.
I tried to match line and diamond colours to team colours.
Dolphins QB's are shown as bars and not lines for easy viewing.
Also, you can mouse-wheel zoom and you can click and drag the graph around.
You can also left-click and drag a window in order to zoom that area for easier reading, and double-click/mouse-wheel to restore to full size.
Choose view full-size graph to make it a little easier to read.
If you want more info or to play around with it a better way is to click 'FORK AND EDIT'. Then, if you click on 'Traces' you can then select the various QB names and click 'Show' or 'Hide'. You can also choose how the QB's stats are shown on the graph, e.g. bar or line or area etc. The type can be selected for each QB if that makes it easier.
There are lots of different tools on there to play around with - e.g. you can choose to have a hovering mouse display only the stat point you're hovering over, or hover all stats for the year. Play around.
If I have time I'll do one for Passer rating too.
LINK IS HERE. (You don't have to sign up for a free account if you don't want to, just close the window with the usual 'x').
Let me know if you spot any errors! Any changes I make will update live since it's hosted on the website.
If you have any requests I can save alternate versions with other QB's as bars etc. If I get too many though, you might be out of luck. :)
I can always send you the data in CSV format and you can create your own.
Thanks.
Here's a sample image:
EDIT: Added Brady data and edited link above to give access to complete data. Haven't had time to update colours to team colours yet.

Good work Galant!
But.. you might be missing some data points. For example, Tom Brady for 2008 is blank in your plot, but he actually does have a QBR for that year: 59.2:

Also, you might qualify this by saying it's only regular season. As you can see here, Brady's 2014 regular season QBR is 74.6 (what you have) while his postseason is 78.6:

Not sure if this is true, but I think pro-football-reference.com somehow has the combined QBR.. otherwise it's hard to make sense of why their values are different than yours:

Also, one good thing about pro-football-reference.com is you can download the data in CSV format, so it's relatively easy to write a program that parses it.
Anyway, passer rating is probably better than QBR, not just because ESPN doesn't publish their formula, but because they don't even calculate it before 2006.Galant likes this. -

The missing data point is probably because Brady got knocked out of the first game of 2008 and therefore didn't qualify as a rated passer.
