Bitcoin vs. Altcoin aggregated marketcap development

[doolittle]

Hi all, recently I have seen an analysis that shows how much percent of the total cryptocurrency marketcap is due to altcoins, and how much is due to Bitcoin.
Do you know where i can get this analysis?

It was a very interesting chart as it showed how crypto-currencies had spiked in February (when Mastercoin, Litecoin, Dogecoin, Next, Vertcoin, Auroracoin and many others were at record highs) and gone down since.

I saw it and now can't find it again either man
