Python matplotlib.ticker 模块，AutoMinorLocator() 实例源码
我们从Python开源项目中，提取了以下4个代码示例，用于说明如何使用matplotlib.ticker.AutoMinorLocator()。
def theme(ax=None, minorticks=False):
""" update plot to make it nice and uniform """
from matplotlib.ticker import AutoMinorLocator
from pylab import rcParams, gca, tick_params
if minorticks:
if ax is None:
ax = gca()
ax.yaxis.set_minor_locator(AutoMinorLocator())
ax.xaxis.set_minor_locator(AutoMinorLocator())
tick_params(which='both', width=rcParams['lines.linewidth'])
def apply_theme(self, ax):
""""Styles x,y axes to appear like ggplot2
Must be called after all plot and axis manipulation operations have
been carried out (needs to kNow final tick spacing)
From: https://github.com/wrobstory/climatic/blob/master/climatic/stylers.py
"""
# Remove axis border
for child in ax.get_children():
if isinstance(child, mpl.spines.Spine):
child.set_alpha(0)
# Restyle the tick lines
for line in ax.get_xticklines() + ax.get_yticklines():
line.set_markersize(5)
line.set_markeredgewidth(1.4)
# Only show bottom left ticks
ax.xaxis.set_ticks_position('bottom')
ax.yaxis.set_ticks_position('left')
# Set minor grid lines
ax.grid(True, 'minor', color='#F2F2F2', linestyle='-', linewidth=0.7)
if not isinstance(ax.xaxis.get_major_locator(), mpl.ticker.LogLocator):
ax.xaxis.set_minor_locator(mpl.ticker.AutoMinorLocator(2))
if not isinstance(ax.yaxis.get_major_locator(), mpl.ticker.LogLocator):
ax.yaxis.set_minor_locator(mpl.ticker.AutoMinorLocator(2))
def apply_theme(self, ax):
