可视化作业

作业1代码

x = np.linspace(-10,10,50) y = np.sin(x) plt.plot(x,y,'bo:',markerfacecolor = 'r', markersize = 10) plt.title('My Matplotlib pictures') plt.xlabel('x-axis') plt.ylabel('y-axis') plt.annotate("(-5,0)",xy=(-5,0),xytext=(-2.5,0.25),arrowprops=dict(facecolor='green',headwidth = 20, headlength = 20)) plt.annotate("(0,0)",xy=(0,0)) plt.grid() plt.show()

结果如下： 作业2

plt.figure(dpi=600) plt.title('不同果酱面包配料百分比') elements = ['面粉','砂糖','奶油','果酱','坚果'] a = [0.4,0.15,0.2,0.1,0.15] b = [0.3,0.25,0.2,0.1,0.15] colors = ['skyblue','green','blue','orange','pink'] plt.pie(a,autopct="%%",colors = colors,pctdistance=0.8, wedgeprops = {'linewidth':1, 'edgecolor':'white'}) plt.pie(b,radius=0.7,autopct="%%",colors = colors,pctdistance=0.8, wedgeprops = {'linewidth':1.5, 'edgecolor':'white'}) plt.pie([1],colors='w',radius=0.4) #wedgeprops设置边框 plt.legend(elements, fontsize = 10, title = '配料表') plt.show()

结果如下： 作业3

#作业3 ax1 = plt.subplot2grid((3,3),(0,1)) ax2 = plt.subplot2grid((3,3),(1,1)) ax3 = plt.subplot2grid((3,3),(0,0),rowspan=3) ax4 = plt.subplot2grid((3,3),(2,1),colspan=2) ax5 = plt.subplot2grid((3,3),(0,2),rowspan=2)

结果如下： 作业4
