3D Scatter Plots in Julia

How to make 3D scatter plots in Julia with Plotly.

Plotly is known for its graphing libraries, but it's also a broader ecosystem for building interactive data apps, AI data analysis tools, and deploying and hosting Dash apps. Explore the full set of tools and platforms designed to help turn data into action. Discover Plotly.

Note: We are retiring documentation for R, MATLAB, Julia, and F#. Learn more about this change here.

3D scatter plot

Like the 2D scatter plot scatter, the 3D version type="scatter3d" plots individual data in three-dimensional space.

using PlotlyJS, CSV, DataFrames
df = dataset(DataFrame, "iris")
plot(
    df,
    x=:sepal_length, y=:sepal_width, z=:petal_width, color=:species,
    type="scatter3d", mode="markers"
)

Style 3d scatter plot

It is possible to customize the style of the figure through the parameters of scatter_3d for some options, or by updating the traces or the layout of the figure through restyle! or relayout!.

using PlotlyJS, CSV, DataFrames

df = dataset(DataFrame, "iris")
plot(
    df, Layout(margin=attr(l=0, r=0, b=0, t=0)),
    x=:sepal_length, y=:sepal_width, z=:petal_width, color=:species,
    type="scatter3d", mode="markers",
    marker_size=:petal_length, marker_sizeref=0.3,
)

3D Scatter Plot with Colorscaling and Marker Styling

using PlotlyJS
# Helix equation
t = range(0, stop=20, length=100)

plot(scatter(
    x=cos.(t),
    y=sin.(t),
    z=t,
    mode="markers",
    marker=attr(
        size=12,
        color=t,                # set color to an array/list of desired values
        colorscale="Viridis",   # choose a colorscale
        opacity=0.8
    ),
    type="scatter3d"
), Layout(margin=attr(l=0, r=0, b=0, t=0)))
