示例1: qglue
# 需要导入模块: from glue.core import DataCollection [as 别名]
# 或者: from glue.core.DataCollection import extend [as 别名]
def qglue(**kwargs):
"""
Quickly send python variables to Glue for visualization.
The generic calling sequence is::
qglue(label1=data1, label2=data2, ..., [links=links])
The kewyords label1, label2, ... can be named anything besides ``links``
data1, data2, ... can be in many formats:
* A pandas data frame
* A path to a file
* A numpy array, or python list
* A numpy rec array
* A dictionary of numpy arrays with the same shape
* An astropy Table
``Links`` is an optional list of link descriptions, each of which has
the format: ([left_ids], [right_ids], forward, backward)
Each ``left_id``/``right_id`` is a string naming a component in a dataset
(i.e., ``data1.x``). ``forward`` and ``backward`` are functions which
map quantities on the left to quantities on the right, and vice
versa. `backward` is optional
Examples::
balls = {'kg': [1, 2, 3], 'radius_cm': [10, 15, 30]}
cones = {'lbs': [5, 3, 3, 1]}
def lb2kg(lb):
return lb / 2.2
def kg2lb(kg):
return kg * 2.2
links = [(['balls.kg'], ['cones.lbs'], lb2kg, kg2lb)]
qglue(balls=balls, cones=cones, links=links)
:returns: A :class:`~glue.app.qt.application.GlueApplication` object
