OK, how about this one? It, too, shows nearly a doubling of crimes involving firearms in the years after the ban.
BBC NEWS | UK | Analysis: UK gun crime figures
When something is objectively true, you don't need to use skewed studies to make your point.
What is "objectively true"? That laws restricting firearm ownership lead to death? Is that really a claim you're making?
You link to a graph to argue that gun deaths are increasing in the UK, but, according to your linked graph, the number of gun deaths in the UK plateaued and went down the past few years.
Also, the increases you cite must be put in context. As per your article, "According to Home Office figures, there were 59 firearms-related homicides in 2006-07 compared with 49 in the previous year. That is an increase of 18% in just one year." Going from 49 to 59 deaths
per year. That is an entirely different universe from the US, where yearly gun deaths number in the
many thousands. See

It's not so much apples and oranges, as Earth and Mars.
There's no comprehensive analysis in your link as to the effect of any other factors on the numbers. But really, if you want to cite a post-ban increase in yearly gun deaths in the UK from 49 to 59 as some sort of winning argument in the debate about gun safety in the US, so be it.
You want your guns. We get it.
Guns kill people. What else do they do?
