I Just need a good way to generate Z 2D array to fit a surface through the scatter plots generated with the help of X,Y,Z axis.
All i Have is the following:
x : [3, 4, 6, 5, 5, 4, 6, 5, 1, 3, 2, 0, 1, 0, 2, 4, 5, 0, 2, 3, 5, 5, 0, 1, 4, 0, 2, 3, 4, 6, 4, 0, 4, 5, 6, 6, 4, 4, 3, 4, 6, 2, 1, 1, 5, 2, 6, 0, 2, 2]
y : [3, 1, 6, 2, 5, 2, 2, 4, 6, 3, 1, 4, 3, 0, 1, 2, 4, 3, 2, 5, 0, 1, 0, 4, 1, 1, 4, 3, 2, 1, 0, 3, 6, 5, 1, 5, 4, 4, 0, 6, 3, 6, 6, 3, 2, 3, 2, 5, 0, 1]
z : [5, 1, 4, 5, 3, 1, 5, 6, 0, 1, 1, 3, 3, 2, 4, 3, 5, 2, 0, 1, 6, 0, 2, 6, 0, 1, 6, 2, 2, 0, 6, 5, 2, 2, 0, 5, 6, 6, 5, 4, 6, 1, 2, 2, 4, 3, 3, 0, 0, 0]
I have used the following code to generate the Z 2D array. But the plot doesnt pass through most of the points
x=np.asarray([3, 4, 6, 5, 5, 4, 6, 5, 1, 3, 2, 0, 1, 0, 2, 4, 5, 0, 2, 3, 5, 5, 0, 1, 4, 0, 2, 3, 4, 6, 4, 0, 4, 5, 6, 6, 4, 4, 3, 4, 6, 2, 1, 1, 5, 2, 6, 0, 2, 2]);
y=np.asarray([3, 1, 6, 2, 5, 2, 2, 4, 6, 3, 1, 4, 3, 0, 1, 2, 4, 3, 2, 5, 0, 1, 0, 4, 1, 1, 4, 3, 2, 1, 0, 3, 6, 5, 1, 5, 4, 4, 0, 6, 3, 6, 6, 3, 2, 3, 2, 5, 0, 1]);
z=np.asarray([5, 1, 4, 5, 3, 1, 5, 6, 0, 1, 1, 3, 3, 2, 4, 3, 5, 2, 0, 1, 6, 0, 2, 6, 0, 1, 6, 2, 2, 0, 6, 5, 2, 2, 0, 5, 6, 6, 5, 4, 6, 1, 2, 2, 4, 3, 3, 0, 0, 0]);
xi=np.linspace(min(x), max(x),10)
yi=np.linspace(min(y),max(y),10)
zi = griddata((x,y), z, (xi, yi), method='linear')
X,Y= np.meshgrid(xi,yi)
Z = np.nan_to_num(griddata((x,y), z, (X, Y), method='cubic'))
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
ax.scatter(x, y, z)
ax.plot_surface(X, Y, Z, rstride=1, cstride=1, cmap=cm.coolwarm,
linewidth=0, antialiased=False)
plt.savefig('surface.pdf')
print type(Z)
print "["
for row in Z:
print str(list(row)) + ","
print "]"
Please help me with this one. Thanks!
