Plotting Functions – Part 2: Using Polar Coordinates

This is part 2 of a post where we demonstrate how to plot functions in Tableau. Part 1 can be seen here. In this section we are focused on using Polar coordinates. This is a helpful system for recreating shapes that have some sort of circular shape. In Cartesian coordinates, each point is represented by an (x,y) pair; however, in the Polar coordinates, each point is represented by a (r,θ) pair. A few things to keep in mind about angles (θ). A circle has 360 degrees, which

Plotting Functions – Part 1: Using Cartesian Coordinates

In this post, we will demonstrate a method for plotting two-dimensional functions in Tableau. We will present examples in both Cartesian and Polar coordinates. This post focuses on the Cartesian system and the follow-up post focuses on the Polar Coordinate system. Our goal is to demonstrate how to plot functions as the ones shown below: Let’s start by reviewing a few definitions. 2D Cartesian Coordinates, is a system where every point on a plane is defined by a pair of value

Create Map Paths Using Great Circles

A typical map is a two-dimensional representation of a three-dimensional sphere. When we draw paths, we know that the shortest distance between two points is a straight line. Nevertheless, the shortest path on the surface of a sphere does not necessarily look like a straight line on a two-dimensional map. In this post, we explain how to draw paths that connect two locations on a map based on the shortest distance between them using Tableau. We use a concept called great-ci
