Last Updated : 01 Oct, 2020

A Plotly is a Python library that is used to design graphs, especially interactive graphs. It can plot various graphs and charts like histogram, barplot, boxplot, spreadplot, and many more. It is mainly used in data analysis as well as financial analysis. plotly is an interactive visualization library.

Making Custom Buttons

In plotly, actions custom Buttons are used to quickly make actions directly from a record. Custom Buttons can be added to page layouts in CRM, Marketing, and Custom Apps. There are 4 possible methods that can be applied in custom buttons:

restyle: modify data or data attributes
relayout: modify layout attributes
update: modify data and layout attributes
animate: start or pause an animation

Example 1: Using Restyle Method

Python3

import plotly.graph_objects as px
import numpy as np


# creating random data through randomint
# function of numpy.random
np.random.seed(42)

random_x = np.random.randint(1, 101, 100)
random_y = np.random.randint(1, 101, 100)

plot = px.Figure(data=[px.Scatter(
    x=random_x,
    y=random_y,
    mode='markers',)
])

# Add dropdown
plot.update_layout(
    updatemenus=[
        dict(
            type="buttons",
            direction="left",
            buttons=list([
                dict(
                    args=["type", "scatter"],
                    label="Scatter Plot",
                    method="restyle"
                ),
                dict(
                    args=["type", "bar"],
                    label="Bar Chart",
                    method="restyle"
                )
            ]),
        ),
    ]
)

plot.show()

Output:

Example 2: Using Update method

Python3

import plotly.graph_objects as px
import numpy


# creating random data through randomint
# function of numpy.random
np.random.seed(42)

random_x = np.random.randint(1, 101, 100)
random_y = np.random.randint(1, 101, 100)

x = ['A', 'B', 'C', 'D']

plot = px.Figure(data=[go.Bar(
    name='Data 1',
    x=x,
    y=[100, 200, 500, 673]
),
    go.Bar(
    name='Data 2',
    x=x,
    y=[56, 123, 982, 213]
)
])


# Add dropdown
plot.update_layout(
    updatemenus=[
        dict(
            type="buttons",
            direction="left",
            buttons=list([
                dict(label="Both",
                     method="update",
                     args=[{"visible": [True, True]},
                           {"title": "Both"}]),
                dict(label="Data 1",
                     method="update",
                     args=[{"visible": [True, False]},
                           {"title": "Data 1",
                            }]),
                dict(label="Data 2",
                     method="update",
                     args=[{"visible": [False, True]},
                           {"title": "Data 2",
                            }]),
            ]),
        )
    ])

plot.show()
