What is density contours In plotly?

This recipe explains what is density contours In plotly

Recipe Objective

What is density contours In plotly? Explain with example.

Density Contours also known as 2D histograms, it is computed by grouping a set of points specified by their x and y coordinates into bins and also if z is provided it will be applied as a aggregation function for e.g sum or count etc to compute the value to be used to compute contours. These are nothing but the 2 dimensional genralization of histograms which resembles a contour plot.

Step 1 - Import libraries

import plotly.express as px import seaborn as sns

Step 2 - load Dataset

Sample_data = sns.load_dataset('iris') Sample_data.head()

Step 3 - Plot the graph

fig = px.density_contour(Sample_data, x="sepal_length", y="petal_length", color="species") fig.show()
