A picture is worth of thousand words; a chart is worth of thousand sets of data. In this tutorial, we are going to learn how we can use graph in Excel to visualize our data.
What is a chart?
A chart is a visual representative of data in both columns and rows. Charts are usually used to analyse trends and patterns in data sets. Let’s say you have been recording the sales figures in Excel for the past three years. Using charts, you can easily tell which year had the most sales and which year had the least. You can also draw charts to compare set targets against actual achievements.
We will use the following data for this tutorial.
Note: we will be using Excel 2013. If you have a lower version, then some of the more advanced features may not be available to you.
Types of Charts in MS Excel
Different scenarios require different types of charts. Towards this end, Excel provides a number of chart types that you can work with. The type of chart that you choose depends on the type of data that you want to visualize. To help simplify things for the users, Excel 2013 and above has an option that analyses your data and makes a recommendation of the chart type that you should use.
The following table shows some of the most commonly used Excel charts and when you should consider using them.
