3D Surface Plots in Python

How to make 3D-surface plots in Python

New to Plotly?

Plotly's Python library is free and open source! Get started by downloading the client and reading the primer.
You can set up Plotly to work in online or offline mode, or in jupyter notebooks.
We also have a quick-reference cheatsheet (new!) to help you get started!

Topographical 3D Surface Plot

In [2]:
import plotly.plotly as py
import plotly.graph_objs as go

import pandas as pd

# Read data from a csv
z_data = pd.read_csv('https://raw.githubusercontent.com/plotly/datasets/master/api_docs/mt_bruno_elevation.csv')

data = [
    go.Surface(
        z=z_data.as_matrix()
    )
]
layout = go.Layout(
    title='Mt Bruno Elevation',
    autosize=False,
    width=500,
    height=500,
    margin=dict(
        l=65,
        r=50,
        b=65,
        t=90
    )
)
fig = go.Figure(data=data, layout=layout)
py.iplot(fig, filename='elevations-3d-surface')
