How to Make Pairplot with Seaborn in Python?

Pairplot of Select Variables Seaborn

When you have multiple variables you might want to quickly look at how each variable is distributed and how each variable is related to other variables. Basically, we are interested in histograms of each variable and scatter plots for all pairs of variables. Seaborn’s pairplot enables us to make such a plot containing a matrix… Continue reading How to Make Pairplot with Seaborn in Python?

How To Facet a Scatter Plot with Altair?

Faceting in Altair

Faceting is a great technique to simplify a complex visualization. Faceting splits a single plot into multiple smaller plots containing subset of data corresponding to a group. This tutorial we will see an example of how to facet a scatter plot with Altair in Python. Let us first load the packages needed to use Altair… Continue reading How To Facet a Scatter Plot with Altair?

How to Reorder bars in barplot with ggplot2 in R

Descending order barplots in ggplot2

In this post, we will learn how to order bars in a barplot using ggplot2 in R. When we make barplot with ggplot2 on a character variable it places the group in alphabetical order. Here we will learn to use two functions, reorder() from base R and fct_reorder() function from forcats package to order the… Continue reading How to Reorder bars in barplot with ggplot2 in R
