情节图例掩盖了图中的情节线
Plot legend obscures plot lines in figure
我正在使用在 matplotlib's gallery:
中找到的代码
import numpy as np
import matplotlib.pyplot as plt
fig = plt.figure()
x = np.arange(10)
y = 2.5 * np.sin(x / 20 * np.pi)
yerr = np.linspace(0.05, 0.2, 10)
plt.errorbar(x, y + 3, yerr=yerr, label='both limits (default)')
plt.errorbar(x, y + 2, yerr=yerr, uplims=True, label='uplims=True')
plt.errorbar(x, y + 1, yerr=yerr, uplims=True, lolims=True,
label='uplims=True, lolims=True')
upperlimits = [True, False] * 5
lowerlimits = [False, True] * 5
plt.errorbar(x, y, yerr=yerr, uplims=upperlimits, lolims=lowerlimits,
label='subsets of uplims and lolims')
plt.legend(loc='lower right')
并且,我在 jupyter 的终端中收到以下输出:
但是,在 matplotlib 库中,图例很好地隐藏在错误栏限制选择以下:
我该如何解决这个问题?我目前在我的项目中遇到了与其他几个情节相同的问题,因为传说阻碍了情节,到目前为止我没有取得任何进展。
对于这个例子,在最后简单地添加 plt.tight_layout()
似乎可以修复重叠。
import numpy as np
import matplotlib.pyplot as plt
fig = plt.figure()
x = np.arange(10)
y = 2.5 * np.sin(x / 20 * np.pi)
yerr = np.linspace(0.05, 0.2, 10)
plt.errorbar(x, y + 3, yerr=yerr, label='both limits (default)')
plt.errorbar(x, y + 2, yerr=yerr, uplims=True, label='uplims=True')
plt.errorbar(x, y + 1, yerr=yerr, uplims=True, lolims=True,
label='uplims=True, lolims=True')
upperlimits = [True, False] * 5
lowerlimits = [False, True] * 5
plt.errorbar(x, y, yerr=yerr, uplims=upperlimits, lolims=lowerlimits,
label='subsets of uplims and lolims')
plt.legend(loc='lower right')
plt.tight_layout() # <- add this
但是,为了保持一致性,您可以调整图形的大小以避免图例重叠。
对于此示例,它将是:
import numpy as np
import matplotlib.pyplot as plt
fig = plt.figure(figsize=(7,5)) # <- add a figsize
x = np.arange(10)
y = 2.5 * np.sin(x / 20 * np.pi)
yerr = np.linspace(0.05, 0.2, 10)
plt.errorbar(x, y + 3, yerr=yerr, label='both limits (default)')
plt.errorbar(x, y + 2, yerr=yerr, uplims=True, label='uplims=True')
plt.errorbar(x, y + 1, yerr=yerr, uplims=True, lolims=True,
label='uplims=True, lolims=True')
