[Matplotlib-users] scatter3D error (color + transparancy)

[Diego A. <die...@gm...>]

dear all,
this is my code:

*import numpy as np*

*import matplotlib.pyplot as plt*

*from mpl_toolkits.mplot3d import Axes3D*

*data1Dx = np.genfromtxt('output.dat')*

*xp = data1Dx[:,0]*

*yp = data1Dx[:,1]*

*zpA = data1Dx[:,1]*0+5*

*CA = data1Dx[:,2]*

*CB = data1Dx[:,3]*

*# Create Map*

*cm = plt.get_cmap("RdYlGn")*

*# 3D Plot*

*fig = plt.figure()*

*ax3D = fig.add_subplot(111, projection='3d')*

*ax3D.scatter(xp, zpA,yp, s=10, c=CA, marker='o',edgecolor='none',alpha=0.1)
*

*plt.show()*

*
*

I am not able to set the color according to vector CA, all scatters became
blue.

*
*

the same thing happens when I put:

#fig.savefig('test.png',format='png',bbox_inches='tight')


to overcome this problems I set:


*def forceUpdate(event):*

*    global scatCollection*

*    scatCollection.changed()*

*fig.canvas.mpl_connect('draw_event',forceUpdate)*

*
*

However the transparency "alpha" does not works.


do you think that is this a bugs?

I am running python on ubuntu 12.10


 thanks


Diego
