简单的画图 代码：import matplotlib.pyplot as pltimport numpy as np# 在[0,1]之间间隔相等取样x = np.linspace(0, 1, 5)y = 2*x + 1# 使用指定xy画图plt.plot(x, y)# 显示图像plt.show()...

这里显示两个figure，即两个窗口，第一个figure显示一个函数，第二个figure显示两个函数 代码：import matplotlib.pyplot as pltimport numpy as np# 定义数据x = np.linspace(-3, 3, 50)y1 = 2*x + 1y2 = x**2# 第一个figureplt.figure()plt.plot...

坐标轴设置import matplotlib.pyplot as pltimport numpy as np# 定义数据x = np.linspace(-3, 3, 50)y1 = 2*x + 1y2 = x**2# 定义figureplt.figure()# 绘图(x,y2)plt.plot(x, y2)# 绘图(x,y1)plt.plot(x, y1, color...

将x轴或者y轴横移。import matplotlib.pyplot as pltimport numpy as np# 定义数据x = np.linspace(-3, 3, 50)y1 = 2*x + 1y2 = x**2# 定义figureplt.figure()# 绘图(x,y2)plt.plot(x, y2)# 绘图(x,y1)plt.plot(x, y1, ...

对于每一个函数有自己的说明import matplotlib.pyplot as pltimport numpy as np# 设置数据x = np.linspace(-3, 3, 50)y1 = 2*x + 1y2 = x**2plt.figure()# set x limitsplt.xlim((-1, 2))plt.ylim((-2, 3))# set new...

在图表自定义相关的说明import matplotlib.pyplot as pltimport numpy as np# 设置数据x = np.linspace(-3, 3, 50)y = 2*x + 1# 定义figure，绘图plt.figure(num=1, figsize=(8, 5),)plt.plot(x, y,) # plt.scatter(x, y,) 散...

设置坐标刻度透明度import matplotlib.pyplot as pltimport numpy as np# 设置数据x = np.linspace(-3, 3, 50)y = 0.1*x# 绘图plt.figure()plt.plot(x, y, linewidth=10, zorder=1) # set zorder for ordering the ...

随机生成一些散点，并绘图import matplotlib.pyplot as pltimport numpy as npn = 1024 # data size# 正太分布X = np.random.normal(0, 1, n)Y = np.random.normal(0, 1, n)T = np.arctan2(Y, X) # 根据xy值设置颜色plt....

随机生成数据，以柱状图形式显示import matplotlib.pyplot as pltimport numpy as npn = 12X = np.arange(n)# np.random.uniform(0.5, 1.0, n) 在[0.5 1.0)随机生成n个浮点数Y1 = (1 - X / float(n)) * np.random.uniform(0.5, 1.0,...
