In this guide, we will learn how to import OpenStreetMap (OSM) data in Stata via QGIS. This allows us to make detailed choropleth maps from several spatial layers:

In this guide learn how to create your own Stata graph schemes. Additionally, this guide also releases a host of new schemes for your day-to-day Stata use:

Stata schemes are templates that define how graph are drawn. The scheme files are basically text files with a .scheme extension that can be modified and saved in your local directory for use. These text files are fairly extensive with well over 1700 options for fine tuning various graph elements including colors, backgrounds, sizes, legends, text etc.

Despite the flexibility of generating schemes, surprisingly little has been produced over the years. Some of…

This guide will present a series of graph replications for the Du Bois challenge in Stata. W. E. Du Bois was an American sociologist who played a pivotal role both in his research work on the black community in the USA, and creating unique visualizations during the early 1900s. At that point, there were no computers or reference guides, so the images were drawn using pens, rulers, compasses, and threads.

When the challenge was posted online, most people were replicating the figures in R or Tableau, or other dataviz-centered languages. My interest was to replicate the graphs in Stata. Du…

In this guide we will learn how to reprogram maps in Stata:

In this guide, learn how to make spirals and wrap text around them in Stata:

So why are we making spirals in Stata especially when they have a limited application? First, purely as a programming challenge in Stata. Second, this guide leads into some visualization replications like the DuBois challenge (#DuBoisChallenge on Twitter), and will be therefore referenced in later posts.

The guide also touches upon string functions for text formatting, and the use of modulus for generating the angles.

Preamble

Like other guides, a basic knowledge of Stata is assumed. …

This guide covers one of the most under-documented features of Stata: regular expressions, or regex for short. In this guide we will learn how to implement the regex features shown in the Stata cheat sheet below. This includes learning about quantifiers, building specific to generic expressions from bottom-up, word boundaries, and learning about greedy versus possessive matching:

Regex is the core algorithm that is used for searching through text using pattern matching. One comes across online regex implementations almost daily. These include auto checking whether you have filled your email address correctly, or whether your password has sufficient characters or…

In this guide learn to program pie charts from scratch in Stata:

This is a fairly long guide. But it lays the foundation for dealing pies and arcs and their area fills in Stata. This allows for creating and customizing a whole range of visualizations, for example, donut charts, sunburst graphs, pies with different radii, or even half pies. These are all topics for subsequent guides. This guide is fairly advanced and discusses several programming elements. These include cartesian to polar coordinate transformation, matrix rotations, using nested if-else conditions, reshape sorting variables, and customizing color schemes.

Why is this necessary…
