I've found hash rate is a good indicator for difficulty but I wouldn't agree it affects the price that much, the reason being is when you get price spikes all the short sighted multi-pools switch to that particular coin, I find difficulty is a more reliable thing and of course how many coins are in circulation.
For alts yes, for Bitcoin no. People spending thousands on ASICs might dabble in ALTs, but I think most will be pretty constantly be mining BTC to try to get ROI.

Very nice actually! Great work. Suggest anyone looking to get into mining at the moment check them out
Where can I find a historical chart for $ price of btc vs Mh/s
Will some of those charts help?

Of course the hash rate is going to follow the BTC dollar price. More $ to be made, more people will mine.
All I can find without writing some code is the following two charts;
