Configuring ProPlot

Overview

A special object named rc, belonging to the RcConfigurator class, is created on import. This is your one-stop shop for working with builtin matplotlib global settings and the global settings added by proplot. Global settings can be changed on-the-fly using the rc object as follows:

import proplot as plotplot.rc.name = valueplot.rc['name'] = valueplot.rc.update(name1=value1, name2=value2)plot.rc.update({'name1': value1, 'name2': value2})

To apply settings to a particular axes, pass the setting to the format command using either of the following approaches:

import proplot as plotfig, ax = plot.subplots()ax.format(name1=value1, name2=value2)ax.format(rc_kw={'name1': value1, 'name2': value2})

In all of these examples, if the setting name contains dots, you can simply omit the dots. For example, to change the rc[‘title.loc’] property, the following approaches are valid:

import proplot as plot# Apply globallyplot.rc.titleloc = valueplot.rc.update(titleloc=value)# Apply locallyfig, ax = plot.subplots()ax.format(titleloc=value)

Matplotlib settings

Details on the matplotlib settings can be found on this page.

ProPlot settings

ProPlot adds several settings to customize things not covered by matplotlib’s builtin settings. Some of these settings may be more accurately described as “meta-settings”, as they change several matplotlib settings at once (for example, rc.linewidth changes axes edge widths, gridline widths, and tick widths). Other settings are for specific features controlled by ProPlot, like a-b-c labels.

The subplots category controls the default layout for figures and axes. The abc, title, and tick categories control a-b-c label, title, and axis tick label settings. The suptitle, leftlabel, toplabel, rightlabel, and bottomlabel categories control figure title and edge label settings. There are two new additions to the image category, and the new colorbar category controls inset and outer colorbar properties. There is also a new gridminor category for minor gridline settings (note that gridminor inherits grid properties when they are changed). Finally, the land, ocean, rivers, lakes, borders, and innerborders categories control various GeoAxes settings.

The .proplotrc file

When you install ProPlot for the first time, a .proplotrc file is generated and placed in your home directory. This is just like the matplotlibrc file, but for changing both ProPlot and matplotlib settings. The syntax is basically the same as the matplotlibrc syntax.

To change the default global settings, simply edit and uncomment the entries listed in this file. You can also change the settings for individual projects by placing a .proplotrc file in the same directory as your python scripts or jupyter notebooks, or in an arbitrary parent directory. As an example, a .proplotrc file containing the default settings is shown below.
