What Is a Google Sheets Double Line Graph?

Line Graph

A double line graph is, well, a chart with two lines plotted on it. Each line connects individual data points to show a continuous change over time.

It’s one of the easiest ways to compare two things to identify patterns and trends in your data.

A typical double line graph in Google Sheets is made of five key components:

  1. A title provides a general overview of what is being displayed.
  2. A legend refers to the information being analyzed.
  3. The horizontal (X) axis illustrates the categories being compared over time.
  4. The vertical (Y) axis maps out the scale used to plot data points and is broken up into equal intervals.
  5. The charting area is where the actual values are being plotted.

Now that we’re done with the essentials, let’s dive into the process of creating a two line graph.

Step 1: Prepare Your Data

First, let’s create a simple table comparing the revenue generated by two products from 2010 to 2021.


In our data set, Column A stores the category values we will plot on the x-axis, whereas Column B and Column C represent the actual values which will be used to chart a two-line graph.

Step 2: Create a Double Line Graph in Google Sheets

1. Now that we have our data in place, let’s start off by creating a chart from our original data. Select all of your data (A1:C13), go to the Insert tab, and choose “Chart.

Chances are, you’re going to get a two-line graph right away. However, in our case, Google Sheets decided to automatically generate a column chart instead.

2. If you get anything other than a graph with two lines, you need to manually change the chart type. Double-click on your chart to open the Chart editor, navigate to the Setup tab, and open the “Chart type” drop-down menu.

Under “Line,” choose either “Line chart” or “Smooth line chart” to graph two lines in Google Sheets.

Having done that, you get a simple graph with two lines.
