Apache Superset Quick Start Guide

Overview of this book

Apache Superset is a modern, open source, enterprise-ready business intelligence (BI) web application. With the help of this book, you will see how Superset integrates with popular databases like Postgres, Google BigQuery, Snowflake, and MySQL. You will learn to create real time data visualizations and dashboards on modern web browsers for your organization using Superset. First, we look at the fundamentals of Superset, and then get it up and running. You'll go through the requisite installation, configuration, and deployment. Then, we will discuss different columnar data types, analytics, and the visualizations available. You'll also see the security tools available to the administrator to keep your data safe. You will learn how to visualize relationships as graphs instead of coordinates on plain orthogonal axes. This will help you when you upload your own entity relationship dataset and analyze the dataset in new, different ways. You will also see how to analyze geographical regions by working with location data. Finally, we cover a set of tutorials on dashboard designs frequently used by analysts, business intelligence professionals, and developers.

Comparing two time series

Stacked charts are often useful for measuring the combined area covered and relative differences in y axis values for two or more series. We will use the time series stacked chart to compare the prices of oranges and bananas:

Setting parameters for the time series stacked chart

The Style section of the chart provides a stream style option. The width of each stream is proportional to the value in that category:

Time series stacked chart

In the stacked chart, the increase in price of both bananas and oranges is visualized through the increasing width of the stream. Since 2010, the color-coded streams show that oranges have had a relatively higher price variance than bananas. We can switch to expand styles and see whether, besides the higher price variation, oranges show a higher upward trend in prices:

Changing the variation
