Re: [Matplotlib-users] 2D data plotted in a 3D plot by adding time flow dimension

[Benjamin R. <ben...@ou...>]

Looks like nabble swallowed your code snippet. Here it is:

```

import matplotlib.pyplot as plt
import mpl_toolkits.mplot3d.axes3d as p3
import numpy.random as rnd
import numpy as np

TILL = 200 # just to have an end in the for loop

def SSI(t): #Simulated Serial Input
	T = np.asarray(t)
	X = np.sin(T)
        Y = np.cos(T)
        return X,Y,T

t = range(0,TILL/2)

plt.ion()
fig = plt.figure()
ax = p3.Axes3D(fig)
#ax = fig.gca(projection='3d') # same result as Axes3D
X,Y,T = SSI(t)
g, = ax.plot(X,Y,T) # for set_data method
#ax.plot(X,Y,T) # not using set_data method

plt.ylim([-1.5,1.5])
plt.xlim([-1.5,1.5])

for i in range(TILL):
	val = rnd.random(1)
	t.append(val)
	t.pop(0)
        X,Y,T = SSI(t)
        #plt.plot(X,Y,T)
        g.set_data(X,Y) #
        #ax.set_zlim(i,i+100) # to make the time axis sliding
        plt.draw()
        #g.axes.figure.canvas.draw() # Same result as plt.draw()


```

Unfortunately, IIRC, set_data() for the 3d objects is probably not what you
want. See https://github.com/matplotlib/matplotlib/issues/1483.
