Plotting Grouped Histograms with Plotly: A Data Visualization Tutorial for Pandas Users
Plot Grid of Histograms Based on Group Variable Using Plotly Overview In this article, we will explore how to plot a grid of histograms based on a group variable using Plotly. We will start by explaining the requirements and then move on to the solution. Requirements We have a data frame that contains multiple variables where each variable is logically connected to a factor level of an additional group variable. Our goal is to plot a histogram of each variable in such a way that it is possible to show a grid of multiple histograms ‘group-wise’.
