`plotly.express`

Jika belum terinstall pada jupyter notebook anda, jalankan pip install plotly pada terminal.

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns
import plotly.express as px

Basic Charts

Line Chart

# using the iris dataset
df = px.data.iris()
 
# plotting the line chart
fig = px.line(df, y="sepal_width")
 
# showing the plot
fig.show()

Apa bedanya dengan line plot biasa?

import matplotlib.pyplot as plt
import seaborn as sns

# plotting the line chart
sns.lineplot(df, y="sepal_width", x=df.index)

# showing the plot
plt.show()

Grouping

# plotting the line chart
fig = px.line(df, y="sepal_width", line_group='species')
 
# showing the plot
fig.show()

# plotting the line chart
fig = px.line(df, y="sepal_width", line_dash='species',
              color='species')
 
# showing the plot
fig.show()

Bar Chart

# Loading the data
df = px.data.tips()
 
# Creating the bar chart
fig = px.bar(df, x='day', y="total_bill")
 
fig.show()

Grouping

# Creating the bar chart
fig = px.bar(df, x='day', y="total_bill", color='sex',
             facet_row='time', facet_col='sex')
 
fig.show()

Scatter Plot

# plotting the scatter chart
fig = px.scatter(df, x='total_bill', y="tip")
 
# showing the plot
fig.show()

Grouping

# plotting the scatter chart
fig = px.scatter(df, x='total_bill', y="tip", color='time',
                 symbol='sex', size='size', facet_row='day',
                 facet_col='time')
 
# showing the plot
fig.show()

Histogram

# plotting the histogram
fig = px.histogram(df, x="total_bill")
 
# showing the plot
fig.show()

Grouping

# plotting the histogram
fig = px.histogram(df, x="total_bill", color='sex',
                   nbins=50, histnorm='percent',
                   barmode='overlay')
 
# showing the plot
fig.show()

Pie Chart

# plotting the pie chart
fig = px.pie(df, values="total_bill", names="day")
 
# showing the plot
fig.show()

Donut Chart

# plotting the donut chart
fig = px.pie(df, values="total_bill", names="day",
             color_discrete_sequence=px.colors.sequential.RdBu,
             opacity=0.7, hole=0.5)
 
# showing the plot
fig.show()

Box Plot

# plotting the boxplot
fig = px.box(df, x="day", y="tip")
 
# showing the plot
fig.show()

Grouping

# plotting the boxplot
fig = px.box(df, x="day", y="tip", color='sex',
             facet_row='time', boxmode='group',
             notched=True)
 
# showing the plot
fig.show()

Violin Plot

# plotting the violin plot
fig = px.violin(df, x="day", y="tip")
 
# showing the plot
fig.show()

Grouping

# plotting the violin plot
fig = px.violin(df, x="day", y="tip", color='sex',
                facet_row='time', box=True)
 
# showing the plot
fig.show()

3D Plot

# plotting the figure
fig = px.scatter_3d(df, x="total_bill", y="sex", z="tip")
 
fig.show()

Grouping

# plotting the figure
fig = px.scatter_3d(df, x="total_bill", y="sex", z="tip", color='day', 
                    size='total_bill', symbol='time')
 
fig.show()

Adding interaction

Untuk memunculkan tombol-tombol interaktif pada plot, kita menggunakan submodule dari library plotly yaitu plotly.graph_objects

Dropdown Menu

import plotly.graph_objects as go

plot = go.Figure(data=[go.Scatter(
    x=df['day'],
    y=df['tip'],
    mode='markers',)
])
 
# Add dropdown
plot.update_layout(
    updatemenus=[
        dict(buttons=list([
            dict(
                args=["type", "scatter"],
                label="Scatter Plot",
                method="restyle"
            ),
            dict(
                args=["type", "bar"],
                label="Bar Chart",
                method="restyle"
            )
        ]),
            direction="down",
        ),
    ]
)
 
plot.show()

plotly.graph_objects

Pada saat kita menggunakan plotly.express (px), secara tidak langsung kita menggunakan plotly.graph_objects untuk menghasilkan suatu plot karena plotly.express dibangun di atas plotly.graph_objects, sehingga kedua library ini pada dasarnya memiliki fungsi yang sama. Hanya saja penggunaan pada plotly.express jauh lebih simple dan bersih.

Buttons

plot = go.Figure(data=[go.Scatter(
    x=df['day'],
    y=df['tip'],
    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()

Sliders and Selectors

x = df['total_bill']
y = df['tip']
 
plot = go.Figure(data=[go.Scatter(
    x=x,
    y=y,
    mode='markers',)
])
 
plot.update_layout(
    xaxis=dict(
        rangeselector=dict(
            buttons=list([
                dict(count=1,
                    step="day",
                    stepmode="backward"),
            ])
        ),
        rangeslider=dict(
            visible=True
        ),
    )
)
 
plot.show()
