Methods

The updatemenu method determines which plotly.js function will be used to modify the chart. There are 4 possible methods:

  • "restyle": modify data or data attributes
  • "relayout": modify layout attributes
  • "update": modify data and layout attributes; combination of "restyle" and "relayout"
  • "animate": start or pause an animation)

Restyle Button

The "restyle" method should be used when modifying the data and data attributes of the graph.
Update One Data Attribute
This example demonstrates how to update a single data attribute: chart type with the "restyle" method.

import plotly.graph_objects as go

import pandas as pd

# load dataset
df = pd.read_csv("https://raw.githubusercontent.com/plotly/datasets/master/volcano.csv")

# create figure
fig = go.Figure()

# Add surface trace
fig.add_trace(go.Surface(z=df.values.tolist(), colorscale="Viridis"))

# Update plot sizing
fig.update_layout(
    width=800,
    height=900,
    autosize=False,
    margin=dict(t=0, b=0, l=0, r=0),
    template="plotly_white",
)

# Update 3D scene options
fig.update_scenes(
    aspectratio=dict(x=1, y=1, z=0.7),
    aspectmode="manual"
)

# Add dropdown
fig.update_layout(
    updatemenus=[
        dict(
            type = "buttons",
            direction = "left",
            buttons=list([
                dict(
                    args=["type", "surface"],
                    label="3D Surface",
                    method="restyle"
                ),
                dict(
                    args=["type", "heatmap"],
                    label="Heatmap",
                    method="restyle"
                )
            ]),
            pad={"r": 10, "t": 10},
            showactive=True,
            x=0.11,
            xanchor="left",
            y=1.1,
            yanchor="top"
        ),
    ]
)

# Add annotation
fig.update_layout(
    annotations=[
        dict(text="Trace type:", showarrow=False,
                             x=0, y=1.08, yref="paper", align="left")
    ]
)

fig.show()

Update Several Data Attributes
This example demonstrates how to update several data attributes: colorscale, colorscale direction, and line display with the "restyle" method. This example uses the cmocean python package. You can install this package with pip install cmocean.

import plotly.graph_objects as go

import pandas as pd

# load dataset
df = pd.read_csv("https://raw.githubusercontent.com/plotly/datasets/master/volcano.csv")

# Create figure
fig = go.Figure()

# Add surface trace
fig.add_trace(go.Heatmap(z=df.values.tolist(), colorscale="Viridis"))

# Update plot sizing
fig.update_layout(
    width=800,
    height=900,
    autosize=False,
    margin=dict(t=100, b=0, l=0, r=0),
)

# Update 3D scene options
fig.update_scenes(
    aspectratio=dict(x=1, y=1, z=0.7),
    aspectmode="manual"
)

# Add drowdowns
# button_layer_1_height = 1.08
button_layer_1_height = 1.12
button_layer_2_height = 1.065

fig.update_layout(

Relayout Button

The "relayout" method should be used when modifying the layout attributes of the graph.
Update One Layout Attribute

Update Button

The "update" method should be used when modifying the data and layout sections of the graph.
This example demonstrates how to update which traces are displayed while simultaneously updating layout attributes such as the chart title and annotations.

# Load dataset
df = pd.read_csv(
