Hello , i have the following code in matlab and trying to do it in
matplotlib.
I have this code in matlab (in a function showGraphs):
...
m = size(myList, 3);
for k = 1:m
g = myList(:, :, k);
image(g + 1)
axis off
axis square
M(k) = getframe;
end;
and in another file (another function):
...
M = showGraphs(grids)
movie(M, 1)
I did so far:
def showGraphs(data):
data=sc.array([data])
n=sc.shape(data)[2]
for k in range(n):
mydata=data[:,:,k]
#plt.imshow(mydata+1) -->> this doesn't work
Also ,in order to do the animation :
grids=...(result from another function)
result=showGraph(grids)
fig=plt.figure()
ani=animation.FuncAnimation(fig,result,interval=30,blit=True)
plt.show()
Right now the program says "TypeError: 'NoneType' object is not
callable" (it has errors in the animation call)
What should be my approach to this in order to have the animation?
Thank you!
You're getting that error because the second argument to FuncAnimation
(`result` in your example) should be a function (not always; see
example 2 linked below). Right now, if your `showGraphs` function is
defined in full, it returns a value of None, which gets saved to
`result` (hence the error).
You should take a look at some of the image animation examples (ex1
<http://matplotlib.sourceforge.net/examples/animation/dynamic_image.html>,
ex2
<http://matplotlib.sourceforge.net/examples/animation/dynamic_image2.html>).

I did now :
def showGraphs(data):
data=sc.array([data])
n=sc.shape(data)[2]
ims=[]
for k in range(n):
mydata=data[:,:,k]
im=plt.imshow(mydata+1)
ims.append([im])
return ims
and now it gives me "TypeError: Invalid dimensions for image data.
