One of the most common uses of Excel is to make a single line graph based on given data. It’s very useful while analyzing different data and trendlines. In this article, we will learn how to make a single line graph in excel.

What Is a Single Line Graph?

First, we need to know what a single line graph is. Suppose we have data on sales of any particular store of different products. So, if we want to visualize this data or the price of different products, we can simply plot the data and connect the line. This line is the single line graph in excel.

How to Make a Line Graph in Excel with 3 Variables

Usually, we plot data based on a single variable that says the independent variable in the X axis and the dependent variable in the Y axis. But for 3 different variables, we will get 3 different lines. So, to get such a plot, we will select the independent data column and other 3 columns and follow the exact same procedures described above for 3 variables as well. As a result, we will get 3 lines for 3 variables like the below image.

Thing to Remember

  • Firstly, while selecting the columns for a single line graph, we need to be careful about the data type of those cells. If the independent value is not numeric, we will not be able to plot a single line diagram.
  • The amount of data in each column should be the same, otherwise the missing data will not be shown, and Excel will automatically adjust the graph based on previous and next data.
  • Finally, if your columns have headers, excel will automatically detect it and place it in the axis name.
