Imagine you have a result sheet for your students over the last 5 years and want to create a chart in Excel, which takes time. In that case, you are thinking if only there were some small mini-charts in a single cell. Well here is the solution.
Ever had a worksheet of data in Excel and quickly wanted to see the trend in the data?
Sparklines are an excellent way to show in a small space the trends or variations in a large volume of data. Excel 2010, 2013 and 2016 have a cool feature called sparklines that basically lets you create sparklines i.e. mini-charts inside a single Excel cell called ‘Sparklines’. You can add sparklines to any cell and keep it right next to your data. In this way, you can quickly visualize data on a row by row basis.

What are sparklines?
Unlike charts on an Excel worksheet, sparklines are not objects — a sparkline is actually a tiny chart in the background of a cell.
Why use sparklines?
Data presented in a row or column is useful, but patterns can be hard to spot at a glance. The context for these numbers can be provided by inserting sparklines next to the data. Taking up a small area, a sparkline can display a trend based on adjacent data in a clear graphical representation. You can quickly see the relationship between a sparkline and its underlying data, even when your data changes you can see the respective changes in the sparkline immediately.
Case Study: In this example, we will use a database of an electronics shop that contains profits from each product for the last 5 months. We want to see the trend of profit of the particular product beside it. How can we do this?
Answer: Using Sparklines!
