自定义 Rc#

我这里不是要创建一个漂亮的图形,只是要展示一些在运行时自定义 rcParams 的示例。

如果你喜欢交互式工作,并且需要为图形创建不同的默认设置(例如,一套用于出版,一套用于交互式探索),你可能想在自定义模块中定义一些设置默认值的函数,例如:

def set_pub():
    rcParams.update({
        "font.weight": "bold",  # bold fonts
        "tick.labelsize": 15,   # large tick labels
        "lines.linewidth": 1,   # thick lines
        "lines.color": "k",     # black lines
        "grid.color": "0.5",    # gray gridlines
        "grid.linestyle": "-",  # solid gridlines
        "grid.linewidth": 0.5,  # thin gridlines
        "savefig.dpi": 300,     # higher resolution output.
    })

然后,当你进行交互式工作时,你只需要执行:

>>> set_pub()
>>> plot([1, 2, 3])
>>> savefig('myfig')
>>> rcdefaults()  # restore the defaults
customize rc
import matplotlib.pyplot as plt

plt.subplot(311)
plt.plot([1, 2, 3])

# the axes attributes need to be set before the call to subplot
plt.rcParams.update({
    "font.weight": "bold",
    "xtick.major.size": 5,
    "xtick.major.pad": 7,
    "xtick.labelsize": 15,
    "grid.color": "0.5",
    "grid.linestyle": "-",
    "grid.linewidth": 5,
    "lines.linewidth": 2,
    "lines.color": "g",
})
plt.subplot(312)
plt.plot([1, 2, 3])
plt.grid(True)

plt.rcdefaults()
plt.subplot(313)
plt.plot([1, 2, 3])
plt.grid(True)
plt.show()
