Matplotlib 作业¶
1. 绘制如下动画¶
import numpy as np
import matplotlib.animation as animation
import matplotlib.pyplot as plt
fig, ax = plt.subplots(constrained_layout=True)
x = np.arange(0, 2*np.pi, 0.01)
y = np.cos(x)
line, = ax.plot(x, y)
dot, = ax.plot(x[0],y[0],marker='o',color='r')
def init(): # only required for blitting to give a clean slate.
dot.set_data(np.nan,np.nan)
return dot,
def animate(i):
# 你的代码
return dot,
ani = animation.FuncAnimation(# 你的代码 )
ani.save("my_fancy_animation.gif", dpi=80)
2. 绘制如下图形¶
import matplotlib.pyplot as plt
import matplotlib as mpl
# 请换成你的电脑上的字体文件
myfont = mpl.font_manager.FontProperties(fname='/System/Library/Fonts/STHeiti Light.ttc')
def format_axes(fig):
for i, ax in enumerate(fig.axes):
ax.text(0.5, 0.5, "ax%d" % (i+1), va="center", ha="center")
ax.tick_params(labelbottom=False, labelleft=False)
fig = plt.figure()
gs = fig.add_gridspec(2, 3)
# 你的代码
format_axes(fig)
plt.savefig('layout.png',dpi=100,bbox_inches='tight')
