How to label bubble chart/scatter plot with column from Pandas dataframe?
63 Lectures 6 hours
To label bubble charts/scatter plot with column from Pandas dataframe, we can take the following steps −
- Set the figure size and adjust the padding between and around the subplots.
- Create a data frame, df, of two-dimensional, size-mutable, potentially heterogeneous tabular data.
- Create a scatter plot with df.
- Annotate each data point with a text.
- To display the figure, use show() method.
import pandas as pd from matplotlib import pyplot as plt # Set the figure size plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True # Create a dataframe df = pd.DataFrame( dict( x=[1, 3, 2, 4, 5], y=[0, 3, 1, 2, 5], points=['Kiran', 'Raju', 'Raja', 'Javed', 'Rishi'] ) ) # Scatter plot ax = df.plot.scatter(x='x', y='y', alpha=0.5) # Annotate each data point for i, txt in enumerate(df.points): ax.annotate(txt, (df.x.iat[i]+0.05, df.y.iat[i])) plt.show()
