Python draws three-dimensional curves using matplotlib

This article mainly demonstrates how to use matplotlib to draw three-dimensional graphics

The code is as follows:

　　

#-*-coding:utf-8-*-ImportMatplotlib as Mpl fromMpl_toolkits.mplot3dImportAxes3dImportNumPy as NPImportMatplotlib.pyplot as Plt#Set the legend font sizempl.rcparams['legend.fontsize'] = 10Fig=plt.figure ()#set up three-dimensional graphics modeAx = FIG.GCA (projection='3d')#test Datatheta = Np.linspace ( -4 * np.pi, 4 * np.pi, 100) Z= Np.linspace (-4, 4, 100)/4R= z**3 + 1x= R *Np.sin (theta) y= R *Np.cos (theta)#Draw a graphicAx.plot (x, Y, Z, label='parametric curve')#Show Legendax.legend ()#Display GraphicsPlt.show ()
