I have a simple code to plot the points in 3D for Matplotlib as below -
from mpl_toolkits.mplot3d import axes3d
import matplotlib.pyplot as plt
import numpy as np
from numpy import genfromtxt
import csv
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
my_data = genfromtxt('points1.csv', delimiter=',')
points1X = my_data[:,0]
points1Y = my_data[:,1]
points1Z = my_data[:,2]
## I remove the header of the CSV File.
points1X = np.delete(points1X, 0)
points1Y = np.delete(points1Y, 0)
points1Z = np.delete(points1Z, 0)
# Convert the array to 1D array
points1X = np.reshape(points1X,points1X.size)
points1Y = np.reshape(points1Y,points1Y.size)
points1Z = np.reshape(points1Z,points1Z.size)
my_data = genfromtxt('points2.csv', delimiter=',')
points2X = my_data[:,0]
points2Y = my_data[:,1]
points2Z = my_data[:,2]
## I remove the header of the CSV File.
points2X = np.delete(points2X, 0)
points2Y = np.delete(points2Y, 0)
points2Z = np.delete(points2Z, 0)
# Convert the array to 1D array
points2X = np.reshape(points2X,points2X.size)
points2Y = np.reshape(points2Y,points2Y.size)
points2Z = np.reshape(points2Z,points2Z.size)
ax.plot(points1X, points1Y, points1Z, 'd', markersize=8, markerfacecolor='red', label='points1')
ax.plot(points2X, points2Y, points2Z, 'd', markersize=8, markerfacecolor='blue', label='points2')
plt.show()
My problem is that I tried to make a decent surface plot out of these data points that I have. I already tried to use ax.plot_surface() function to make it look nice. For this I eliminated some points, and recalculated the matrix kind of input needed by this function.
However, the graph I generated was far more difficult to interpret and understand. So there might be 2 possibilities: either I am not using the function correctly, or otherwise, the data I am trying to plot is not good for the surface plot.
What I was expecting was 3D graph which would have an effect similar to that we have of 3D pie chart. We see that one piece (that which is extracted out) is part of another piece. I was not expecting it to be exactly same like that, but some kind of effect like that.
What I would like to ask is:
Do you think it will be possible to make such 3D graph?
Is there any way better, I could express my data in 3 dimension?
