Error when using self-defined axes

[LeiGuo0812]

Hi!

I'm trying to plot multiple plots in a figure, but I encounted an error when I try to pass the parameter ax. Here below is a example:

import netplotbrain
import pandas as pd
import matplotlib.pyplot as plt

import netplotbrain
import pandas as pd

# Define the nodes
nodes_df = pd.DataFrame({'x': [40, 10, 30, -15, -25], 
                         'y': [50, 40, -10, -20, 20], 
                         'z': [20, 30, -10, -15, 30]})
# Call netplotbrain to plot

fig, ax = plt.subplots(1,1,figsize=(5,5))
netplotbrain.plot(ax = ax, nodes=nodes_df, arrowaxis=None)

The error:

I'm not sure if I am doing it wrong. Thanks a lot!

Hi,

I think the problem is that you are not using 3D axis from matplotlib

fig  = plt.figure(figsize=(5,5))
ax = fig.add_subplot(111, projection='3d')

Adding the projection='3d' to the axis is the critical bit.

This should solve the problem.

It worked! Thanks a lot!
