boadata 0.3.7

(B)rowser (O)f (A)rbitrary Data - a Python browser of data. The goal is to create a simple tool for scientists / data miners to browse and plot various data sources in one simple environment.

It’s a library, as well as a set of tools.

Concepts

• uri - boadata tries to support odo URIs
• data object - wrapper around basic data types (a.k.a odo.resource but with wrapper)
• data tree - browseable that can contain nodes (some of the nodes can be data objects)
• data conversion - between different object types
• view - visual representation of a data objects

Executables

Run command –help to see full list of options

• boadescribe <uri> - show basic info about a data object (in command-line)
• boatree <uri> - list nodes in a data tree
• boaplot <uri> <colx> <coly> - scatter plot of two columns (colx,y can be expressions like x**2, sqrt(y+2*exp(-x)) etc.)
• boahist <uri> <col> - histogram of a column
• boadata [<uri>] - full gui with a tree
• boatable <uri> - show tabular representation of a dataobject (GUI)
• boacat <uri> - print tabular representation of a dataobject (command-line)
• boaview <uri> - show a tabbed window with all available views for the dataobject
