Plot stacked bar chart using plotly in Python

Here in this post we will plot stacked bar chart using plotly in Python. As everyone say that data is the new oil, but on top of that i can say that data visualization is the tool which adds importance to that oil and without that oil aka data is of no use.

Lets plot the tacked bar chart now.

Code to plot the chart :

Lets first import the libraries which we need to plot the charts, which basically are:

• Plotly for data visualization
• Pandas for data read and data manipulation

import plotly.express as px
import pandas as pd
import plotly.graph_objs as go

Now lets read the data and print the data

data= pd.read_csv(r"C:\Users\WeirdGeek\Desktop\Students.csv")
data.head(20)

Here’s how our data looks like:

Now let’s see the Plotly code to plot stacked bar chart:

fig = px.bar(data,x='Name ', y='Marks', color='Subject',height=400, width=700)
fig.show()

The above code will take the name column on the x axis and marks column on the y axis and to add the color which finally prepare the stacked bar chart we add the Subject to the color attribute. Also, we provided the height and width of the chart.

Here’s how the charts looks like:
