Hey guys,

can someone explain to me this error?

"AttributeError: module 'matplotlib.pyplot' has no attribute 'zlim'"

I try to read in coordinates from a txt file. In each row, the coordinates are separated by a single tabulator.

from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
import csv

fig=plt.figure()
ax=fig.add_subplot(111, projection='3d')
x=[]
y=[]
z=[]
with open('fcc_coordinates_a=1.500000_5rows_5columns_5layers.dat') as csv_file:
    plots = csv.reader(csv_file, delimiter="\t")
    for row in plots:
        x.append(float(row[0]))
        y.append(float(row[1]))
        z.append(float(row[2]))
        
ax.scatter(x,y,z,c='r',marker='o')
ax.set_xlabel('x axis')
ax.set_ylabel('y axis')
ax.set_zlabel('z axis')

plt.show()

plt.xlim(0,7.5)
plt.ylim(0,7.5)
plt.zlim(0,7.5) 

Regards

please, post the full traceback in error tags

If I run it, I get a plot as a result, but the zlim did not work and it gives:

AttributeError: module 'matplotlib.pyplot' has no attribute 'zlim'"

I am using Spyder.

No one having an idea =( ?
Does that mean there might be something wrong with Spyder/Python installation?

Just a shot in the dark ... maybe try plt.set_zlim(0,7.5)?

Thank you. plt.set_zlim(x.y) doesn't work any better, but from your link it looks like using
ax.set_zlim(x,y) is the right way to go. And this gets rid of the error.
