Plot 95% confidence interval errorbar Python Pandas dataframes in Matplotlib
To plot 95% confidence interval errorbar Python Pandas dataframes, we can take the following steps −
- Set the figure size and adjust the padding between and around the subplots.
- Get a dataframe instance of two-dimensional, size-mutable, potentially heterogeneous tabular data.
- Make a dataframe with two columns, category and number.
- Find the mean and std of category and number.
- Plot y versus x as lines and/or markers with attached errorbars.
- To display the figure, use show() method.
Example
import numpy as np import pandas as pd import matplotlib.pyplot as plt plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True df = pd.DataFrame() df['category'] = np.random.choice(np.arange(10), 1000, replace=True) df['number'] = np.random.normal(df['category'], 1) mean = df.groupby('category')['number'].mean() std = df.groupby('category')['number'].std() plt.errorbar(mean.index, mean, xerr=0.5, yerr=2*std, linestyle='--', c='red') plt.show()
