How to plot Andrews curves using Pandas in Python? Last Updated : 21 Mar, 2024 Comments Improve Suggest changes Like Article Like Report Andrews curves are used for visualizing high-dimensional data by mapping each observation onto a function. It preserves means, distance, and variances. It is given by formula: T(n) = x_1/sqrt(2) + x_2 sin(n) + x_3 cos(n) + x_4 sin(2n) + x_5 cos(2n) + … Plotting Andrews curves on a graph can be done using the andrews_curves() method of the plotting module. This function generates a matplotlib plot of Andrews curves, for visualising clusters of multivariate data. Syntax: andrews_curves(frame, class_column, ax=None, samples=200, color=None, colormap=None, **kwargs) Parameters: frame: It is the data to be plotted.class_column: This is the name of the column containing class names.ax: This parameter is a matplotlib axes object. Its default value is None.samples: This parameter is the number of points to plot in each curve.color: This parameter is an optional parameter and it is the list or tuple of colors to use for the different classes.colormap: This parameter is the string/matplotlib colormap object. Its default value is None. Returns: This function returns an object of class matplotlib.axis.Axes Example 1: In the following example, A data frame is made from the CSV file and the data frame is used to plot andrews_curves. Python3 # importing various package import pandas as pd import numpy as np import matplotlib.pyplot as plt # making data frame from csv file df = pd.read_csv( 'C:\\Users\\digital india\\Desktop\\pand.csv' ) # Creating Andrews curves x = pd.plotting.andrews_curves(df, 'animal') # plotting the Curve x.plot() # Display plt.show() Output: Example 2: Python3 # importing various package import pandas as pd import numpy as np import matplotlib.pyplot as plt # making data frame from csv file df = pd.read_csv( 'https://raw.github.com/pandas-dev/' 'pandas/master/pandas/tests/io/data/csv/iris.csv' ) # Creating Andrews curves x = pd.plotting.andrews_curves(df, 'Name') # plotting the Curve x.plot() # Display plt.show() Output: Comment More infoAdvertise with us Next Article How to plot Andrews curves using Pandas in Python?

The .plot() method is the core function for plotting data in Pandas. Depending on the kind of plot we want to create, we can specify various parameters such as plot type (ki 8 min read How to plot Timeseries based charts using Pandas? A series of data points collected over the course of a time period, and that are time-indexed is known as Time Series data.
