[Matplotlib-users] Problems using triplot from file
Hi everybody, I am trying to plot a triangular grid from a textfile using triplot, but all I get is some wired straight line code: import numpy as np import matplotlib.pyplot as plt x, y = np.loadtxt('points.dat', unpack=True) triangles = np.loadtxt('triangles.dat', dtype=np.int32) plt.triplot(x, y, triangles, 'go-') Thanks http://old.nabble.com/file/p29815755/points.dat points.dat http://old.nabble.com/file/p29815755/triangles.dat triangles.dat -- View this message in context: http://old.nabble.com/Problems-using-triplot-from-file-tp29815755p29815755.html Sent from the matplotlib - users mailing list archive at Nabble.com. -- Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev ___ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users

Each of these triangles has duplicate vertices and is therefore a straight line. In fact you only have three distinct points in your points.dat file, at (0, 0), (0.05, 0.05), and (0.1, 0.1). You can never construct a triangle which isn't a straight line with these points. Perhaps you intended your points.dat file to be something like 0 0 0 0.05 0 0.1 0.05 0 0.05 0.05 0.05 0.1 0.1 0 0.1 0.05 0.1 0.1 Ian -- Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev___ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users
