BUG: qbstyles adds automatic axis ticks that are not consistent with the data displayed when one subplot is used

[mathilde-lavacquery]

Same image with qbstyles activated and deactivated: x-axis and y-axis are not indexed properly in the first image

# LINE PLOT
def line_plot(ax):
    rng = np.random.RandomState(4)
    x = np.linspace(0, 10, 500)
    y = np.cumsum(rng.randn(500, 4), 0)
    ax.set_title('Line Graph')
    ax.set_xlabel('— Time')
    ax.set_ylabel('— Random values')
    ax.legend(['Bitcoin', 'Ethereum', 'Dollar', 'Oil'])
    ax.set_xlim([0, 10])
    ax.set_ylim([-20, 60])
    ax.plot(x, y)

fig, ax = plt.subplots(figsize=(16, 9))
line_plot(ax)

Same issue, it's pretty bizarre.

Having this same issue as well, sadly!

Hacky workaround by typing print(plt.rcParams) to get all rcparams, then copy and paste all those rc parameters separately. Don't use mpl_style(). You might need to restart your kernel for the changes to appear.

[simfinite]

Same problem here. It seems to be related to the minor-ticks. The mpl_style docstring says something about having to monkey-patch mpl. If minor ticks are not essential, one can call mpl_style(minor_ticks=False) to disable them (along with the monkey-patching).

[louisdecharson]

I had the same issue and it seems that it can be fixed by removing the monkey patch on figure and keeping it on subplots.

Examples

import marplotlib.pyplot as plt 
mpl_style(minor_ticks=False)
original_subplots = plt.subplots


def _style_ticks(axis, color):
    """Enable minor ticks, and color major + minor ticks"""
    axis.minorticks_on()
    ticks = (
        axis.get_xticklines()
        + axis.xaxis.get_minorticklines()
        + axis.get_yticklines()
        + axis.yaxis.get_minorticklines()
    )
    for tick in ticks:
        tick.set_color("#" + color + "3D")


def _monkey_patch_subplot(color, subplot):
    """Style all axes of a figure containing subplots, just after the
    figure is created."""

    def _patch(*args, **kwargs):
        fig, axes = subplot(*args, **kwargs)
        axes_list = [axes] if isinstance(axes, matplotlib.axes.Axes) else axes
        for ax in axes_list:
            if isinstance(ax, matplotlib.axes.Axes):
                _style_ticks(ax, color)
            else:
                for each in ax:
                    _style_ticks(each, color)
        return fig, axes

    return _patch


plt.subplots = _monkey_patch_subplot("FFFFFF", original_subplots)

Note for the maintainer(s), the color argument does not seem to have any effect.
