class CartesianAxes(*args, **kwargs)[source]

Bases: proplot.axes.shared._SharedAxes, proplot.axes.plot.PlotAxes

Axes subclass for plotting in ordinary Cartesian coordinates. Adds the format method and overrides several existing methods.

Parameters

  • aspect ({'auto', 'equal'} or float, optional) – The data aspect ratio. See set_aspect for details.

  • xlabel, ylabel (str, optional) – The x and y axis labels. Applied with set_xlabel and set_ylabel.

  • xlabelpad, ylabelpad (unit-spec, optional) – The padding between the x and y axis bounding box and the x and y axis labels. Default is rc['label.pad'] = 4.0. If float, units are points. If string, interpreted by units.

  • xlabel_kw, ylabel_kw (dict-like, optional) – Additional settings used to update the axis labels with text.update().

  • xlim, ylim (2-tuple of floats or None, optional) – The x and y axis data limits. Applied with set_xlim and set_ylim.

  • xmin, ymin (float, optional) – The x and y minimum data limits. Useful if you do not want to set the maximum limits.

  • xmax, ymax (float, optional) – The x and y maximum data limits. Useful if you do not want to set the minimum limits.

  • xreverse, yreverse (bool, optional) – Whether to “reverse” the x and y axis direction. Makes the x and y axes ascend left-to-right and top-to-bottom, respectively.

  • xscale, yscale (scale-spec, optional) – The x and y axis scales. Passed to the Scale constructor. For example, xscale='log' applies logarithmic scaling, and xscale=('cutoff', 100, 2) applies a CutoffScale.

  • xscale_kw, yscale_kw (dict-like, optional) – The x and y axis scale settings. Passed to Scale.

  • xloc, yloc (optional) – Shorthands for xspineloc, yspineloc.

  • xspineloc, yspineloc ({'bottom', 'top', 'left', 'right', 'both', 'neither', 'none', 'zero', 'center'} or 2-tuple, optional) – The x and y spine locations. Applied with set_position. Propagates to tickloc unless specified otherwise.

  • xtickloc, ytickloc ({'bottom', 'top', 'left', 'right', 'both', 'neither', 'none'}, optional) – Which x and y axis spines should have major and minor tick marks. Inherits from spineloc by default and propagates to ticklabelloc unless specified otherwise.

  • xticklabelloc, yticklabelloc ({'bottom', 'top', 'left', 'right', 'both', 'neither', 'none'}, optional) – Which x and y axis spines should have major tick labels. Inherits from tickloc by default and propagates to labelloc and offsetloc unless specified otherwise.

  • xlabelloc, ylabelloc ({'bottom', 'top', 'left', 'right'}, optional) – Which x and y axis spines should have axis labels. Inherits from ticklabelloc by default (if ticklabelloc is a single side).

  • xoffsetloc, yoffsetloc ({'left', 'right'}, optional) – Which x and y axis spines should have the axis offset indicator. Inherits from ticklabelloc by default (if ticklabelloc is a single side).

  • xtickdir, ytickdir, tickdir ({'out', 'in', 'inout'}) – Direction that major and minor tick marks point for the x and y axis. Use tickdir to control both.

  • xticklabeldir, yticklabeldir ({'in', 'out'}) – Whether to place x and y axis tick label text inside or outside the axes.

  • xticklabelpad, yticklabelpad (unit-spec, optional) – The padding between the x and y axis ticks and tick labels. Default is rc['tick.labelpad']. If float, units are points. If string, interpreted by units.

  • xticks, yticks (optional) – Aliases for xlocator, ylocator.

  • xlocator, ylocator (locator-spec, optional) – Used to determine the x and y axis tick mark positions. Passed to the Locator constructor. Can be float, list of float, string, or matplotlib.ticker.Locator instance. Use [], 'null', or 'none' for no ticks.

  • xlocator_kw, ylocator_kw (dict-like, optional) – Keyword arguments passed to the matplotlib.ticker.Locator class.

  • xminorticks, yminorticks (optional) – Aliases for xminorlocator, yminorlocator.

  • xminorlocator, yminorlocator (optional) – As for xlocator, ylocator, but for the minor ticks.

  • xticklabels, yticklabels (optional) – Aliases for xformatter, yformatter.

  • xformatter, yformatter (formatter-spec, optional) – Used to determine the x and y axis tick label string format. Passed to the Formatter constructor. Can be string, list of strings, or matplotlib.ticker.Formatter instance. Use [], 'null', or 'none' for no labels.

  • xformatter_kw, yformatter_kw (dict-like, optional) – Keyword arguments passed to the matplotlib.ticker.Formatter class.

  • xrotation, yrotation (float, optional) – The rotation for x and y axis tick labels. Default is 0 for normal axes, rc['formatter.timerotation'] = 'vertical' for time x axes.

  • xbounds, ybounds (2-tuple of float, optional) – The x and y axis data bounds within which to draw the spines. For example, the axis range (0, 4) with bounds (1, 4) will prevent the spines from meeting at the origin.

  • xtickrange, ytickrange (2-tuple of float, optional) – The x and y axis data ranges within which major tick marks are labelled. For example, the tick range (-1, 1) with axis range (-5, 5) and a tick interval of 1 will only label the ticks marks at -1, 0, and 1. See AutoFormatter for details.

  • xwraprange, ywraprange (2-tuple of float, optional) – The x and y axis data ranges with which major tick mark values are wrapped. For example, the wrap range (0, 3) causes the values 0 through 9 to be formatted as 0, 1, 2, 0, 1, 2, 0, 1, 2, 0. See AutoFormatter for details.

  • xmargin, ymargin, margin (float, optional) – The default margin between plotted content and the x and y axis spines. Value is proportional to the width, height of the axes. Use this if you want whitespace between plotted content and the spines, but don’t want to explicitly set xlim or ylim.

  • xticklen, yticklen, ticklen (float or str, optional) – Tick lengths for the x and y axis. Default is rc.ticklen. If float, units are points. If string, interpreted by units. Minor tick lengths are scaled according to rc['tick.lenratio'] = 0.5. Use ticklen and ticklenratio to set both at once.

  • xlinewidth, ylinewidth, linewidth (color-spec, optional) – Line width for the x and y axis spines and major ticks. Use linewidth to set both at once.

  • xcolor, ycolor, color (color-spec, optional) – Color for the x and y axis spines, ticks, tick labels, and axis labels. Use color to set both at once.

  • xgridcolor, ygridcolor, gridcolor (color-spec, optional) – Color for the x and y axis major and minor gridlines. Use gridcolor to set both at once.

  • fixticks (bool, optional) – Whether to always transform the tick locators to a FixedLocator instance. Default is False. If your axis ticks are doing weird things (for example, ticks drawn outside of the axis spine), try setting this to True.

  • *args, **kwargs – Passed to proplot.axes.Axes.

Other Parameters

  • title (str, optional) – The axes title.

  • abc (bool or str, optional) – The “a-b-c” subplot label style. Must contain the character a or A, for example 'a.', or 'A'. If True then the default style of 'a' is used. The a or A is replaced with the alphabetic character matching the number. If number is greater than 26, the characters loop around to a, …, z, aa, …, zz, aaa, …, zzz, etc.

  • abcloc, titleloc (str, optional) – Strings indicating the location for the a-b-c label and main title. The following locations are valid (defaults are rc['abc.loc'] = 'left' and rc['title.loc'] = 'center'):

    Location

    Valid keys

    center above axes

    'center', 'c'

    left above axes

    'left', 'l'

    right above axes

    'right', 'r'

    lower center inside axes

    'lower center', 'lc'

    upper center inside axes

    'upper center', 'uc'

    upper right inside axes

    'upper right', 'ur'

    upper left inside axes

    'upper left', 'ul'

    lower left inside axes

    'lower left', 'll'

    lower right inside axes

    'lower right', 'lr'

  • abcborder, titleborder (bool, optional) – Whether to draw a white border around titles and a-b-c labels positioned inside the axes. This can help them stand out on top of artists plotted inside the axes. Defaults are rc['abc.border'] = True and rc['title.border'] = True.

  • abcbbox, titlebbox (bool, optional) – Whether to draw a white bbox around titles and a-b-c labels positioned inside the axes. This can help them stand out on top of artists plotted inside the axes. Defaults are rc['abc.bbox'] = False and rc['title.bbox'] = False.

  • abc_kw, title_kw (dict-like, optional) – Additional settings used to update the a-b-c label and title with text.update().

  • titlepad (float, optional) – The padding for the inner and outer titles and a-b-c labels in arbitrary units (default is points). Default is rc['title.pad'] = 5.0.

  • titleabove (bool, optional) – Whether to try to put outer titles and a-b-c labels above panels, colorbars, or legends that are above the axes. Default is rc['title.above'] = True.

  • abctitlepad (float, optional) – The horizontal padding between the a-b-c label and title when they are in the same location. Default is rc['abc.titlepad'] = 4.0.

  • ltitle, ctitle, rtitle, ultitle, uctitle, urtitle, lltitle, lctitle, lrtitle (str, optional) – Shorthands for the below keywords.

  • lefttitle, centertitle, righttitle, upperlefttitle, uppercentertitle, upperrighttitle, lowerlefttitle, lowercentertitle, lowerrighttitle (str, optoinal) – Additional titles in specific positions. This works as an alternative to the ax.format(title='Title', titleloc=loc) workflow and permits adding more than one title-like label for a single axes.

  • a, alpha, fc, facecolor, ec, edgecolor, lw, linewidth, ls, linestyle (optional) – Additional settings applied to the background patch, and their shorthands. Defaults are rc['axes.alpha'], rc['axes.facecolor'], rc['axes.edgecolor'], rc['axes.linewidth'], and '-', respectively.

  • rc_mode (int, optional) – The context mode passed to context.

  • rc_kw (dict-like, optional) – An alternative to passing extra keyword arguments. See below.

  • **kwargs – Passed to proplot.config.Configurator.context and used to update the axes-relevant rc settings. For example, abc='A.' modifies the rc.abc setting, titleloc='left' modifies the rc['title.loc'] setting, gridminor=True modifies the rc.gridminor setting, and gridbelow=True modifies the rc['grid.below'] setting. Many of the keyword arguments documented above are actually applied by updating the rc settings then retrieving the updated settings.
