## Introduction

Line charts are one of the most commonly used visualization tools in data analysis. They are used to represent trends, patterns, and relationships between variables over time. However, sometimes it becomes necessary to compare two different variables with different scales on the same line chart. This is where a line chart with two y-axes in Tableau comes into play.

A line chart with two y-axes is a type of chart that allows you to plot two different variables with different scales on the same chart. This makes it easier to compare and analyze the relationship between the two variables. The left y-axis is typically used for one variable, while the right y-axis is used for the other variable.
