Error installing package with pip

I'm trying to install a charting tool (matplotlib-v1.4.2) for python 3.4 in Windows 7, so far all my trails doesn't seem to do the job.

Attempts:

• I've downloaded pip from GitHub
• python -m pip install matplotlib on Command Prompt[DOS] - No Use

There's a similar question posted here, tried these suggestions too but I get the following error

'$' is not reconginized as an internal or external command.

I'm sure I'm missing something, your step by step guidance on this regard would be much appreciated.
