Elaborate data analyses are possible with the functionality offered by the great numpy, matplotlib, and pytables libraries. However their support for HEP-typical problems (histograms, fitting routines,visualization of those,..) is limited. Dashi is intended to be a thin wrapper around these libraries to provide some useful tools for these problems without obstructing the user the access to the underlying libraries and without being a dependency sink.
The easiest way to install dashi is with pip:
pip install https://github.com/emiddell/dashi/zipball/master
