与矩形相交的线条颜色为红色,其他为蓝色。
演示如下:
实例代码如下:
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.transforms import Bbox
from matplotlib.path import Path
# Fixing random state for reproducibility
np.random.seed(19680801)
left, bottom, width, he
具有不同标记颜色和大小的散点图演示。
演示结果:
实现代码:
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.cbook as cbook
# Load a numpy record array from yahoo csv data with fields date, open, close,
# volume, adj_close from the mpl-data/example director
在主图中背景颜色不知道怎么改,plt.plot()中没有axisbg参数。
但是子图可以对plt.subplot的参数做修改,下面是对子图的背景颜色修改代码
import matplotlib.pyplot as plt
import numpy as np
# Fixing random state for reproducibility
np.random.seed(19680801)
dt = 0.01
t = np.arange(0, 30, dt)
nse1 = np.random.
