`cape.tnakit.plot_mpl`: Matplotlib/Pyplot Interfaces¶

This module contains handles to various matplotlib plotting methods. In particular, it centralizes some of the multiple-line instructions that are used in multiple places. An example is placing labels on one or more corners of the axis window.

It also includes syntax to import modules without raising ImportError.

class cape.tnakit.plot_mpl.MPLHandle(**kw)¶

Container for handles from matplotlib.pyplot

Versions:

2019-12-20 @ddalle: First version

add(h1)¶

Combine two plot handle objects

Attributes of h1 will override those of h except where the attribute is a list. For example, h1.lines will be added to h.lines to get handles to lines from both instances.

Call:

>>> h.add(h1)

Inputs:

h: MPLHandle: Parent handle
h1: MPLHandle: Second handle for collecting all objects

Versions:

2019-12-26 @ddalle: First version

close()¶

Close the open figure, if any

Call:

>>> h.close()

Inputs:

h: MPLHandle: Matplotlib object handle

Versions:

2022-05-17 @ddalle: Version 1.0

save(attr, v)¶

Save one plot object without erasing others

This method provides a simple method to save multiple instances of a certain kind of plot object without having to perform checks manually. For example if h.lines already contains several lines, and L contains several new ones, then h.save("lines", L) will effectively run h.lines += L.

Conversions from single object to list are handled automatically, and items are only added to the list if not already present. Thus running save() several times in a row with the same arguments will not create the illusion of many objects for a given attribute.

Call:

>>> h.save(attr, v)

Inputs:

h: MPLHandle: Matplotlib object handle
attr: str: Name of attribute to save
v: any: Value to save/add for that attribute
