  • 二维绘图

#matlab plot(x,y,'linewidth',3,'r'); xlabel('x','fontsize',20,'fontname','Courier') ylabel('y','fontweight','bold'); #设置坐标范围 axis([xmin xmax ymin ymax])
##matplotlib绘图 import numpy as np import matplotlib.pyplot as plt plt.figure() ax=plt.plot(x,y) ax.set_xlabel('f1') ax.set_ylabel('f2') ax.set_xlim(0,0.8) ax.set_ylim(0,0.8)

  • 三维绘图

#matlab绘图 plot3(a1,a2,a3,'linewidth',3,'r'); xlabel('x','fontsize',20,'fontname','Courier') ylabel('y','fontweight','bold'); Zlabel('y','fontweight','bold'); axis([xmin xmax ymin ymax zmin zmax])
##matplotlib绘图 import numpy as np import matplotlib.pyplot as plt from mpl_toolkits.mplot3d import Axes3D import pandas as pd file=pd.read_excel('ok.xlsx',has_index_names=None) c1,c2,c3=file.c1,file.c2,file.c3 fig=plt.figure() ax=fig.add_subplot(111,projection='3d') ax.scatter(c1,c2,c3,c='r',marker='o') ax.set_xlabel('f1') ax.set_ylabel('f2') ax.set_zlabel('f3') ax.set_xlim(0,0.8) ax.set_ylim(0,0.8) ax.set_zlim(0,6) plt.show()
