How to create a Dual Axis Chart in Tableau?

Introduction

A dual axis chart can be used to combine data with two different scales into one graph. This makes it easier to have all of your data in one place in a more simplistic manner. Dual axis charts are used when the variables have different units. For example, a dual axis chart can be used when comparing two different units of measure with different variables i.e. Sales and Profit for the Month.

Tableau is a visual analytics platform which is widely used in order to demonstrate data for different fields. In this blog I will show you how to create a Dual Axis chart for tableau specifically.
