An area chart or area graph displays graphically quantitative data. It is based on the line chart. The area between axis and line are commonly emphasized with colors, textures and hatching. Commonly one compares two or more quantities with an area chart.

Reading Data –

Let’s read a dataset to work with.

import pandas as pd
url = ''
df = pd.read_csv(url, parse_dates=['Date'])
df.drop('Unnamed: 0', axis=1, inplace=True)

Create an Area Chart with Plotly Express –

To create an Area Chart in Plotly Express we use the px.area function.

import as px
fig = px.area(df, x='Date', y='Open', color='Symbol')

Create an Area Chart with Plotly Graph Objects –

We can also create an Area chart with plotly graph objects using the go.Scatter function.

# stock data for different companies
apple_df = df[df['Symbol']=='AAPL']
google_df = df[df['Symbol']=='GOOG']
tesla_df = df[df['Symbol']=='TSLA']

# create area chart
import plotly.graph_objects as go
fig = go.Figure()
fig.add_trace(go.Scatter(x = apple_df['Date'], y =apple_df['Open'], stackgroup='one', name='AAPL'))
fig.add_trace(go.Scatter(x = google_df['Date'], y =google_df['Open'], stackgroup='one', name='GOOG'))
fig.add_trace(go.Scatter(x = tesla_df['Date'], y =tesla_df['Open'], stackgroup='one', name='TSLA'))
