Add An Average Line To A Bar Chart
Bar charts are an effective way of visually representing data. They are commonly used in reports, presentations, and other forms of communication. However, sometimes it can be difficult to draw conclusions from a bar chart without additional information. One way to provide additional information is by adding an average line to the chart. This article will explain how to do that.
What is an average line?
An average line is a horizontal line that represents the average value of the data being plotted. It is useful because it provides a quick and easy way to see how the individual data points relate to the average. For example, if the average line is above a particular data point, it means that that data point is below average. Conversely, if the average line is below a particular data point, it means that that data point is above average.
How to add an average line to a bar chart
Adding an average line to a bar chart is relatively easy. Here are the steps:
- Calculate the average value of the data being plotted.
- Add a new data series to the chart that consists of a single data point representing the average value.
- Format the new data series as a line.
- Move the new data series to the secondary axis.
- Format the secondary axis so that it uses the same scale as the primary axis.
- Format the line so that it is visible and easy to read.
Once you have completed these steps, you should have a bar chart with an average line.
Why add an average line?
Adding an average line to a bar chart can provide additional context and make it easier to draw conclusions from the data. Here are some of the reasons why you might want to add an average line:
- It can help you quickly see how the individual data points relate to the average.
- It can make it easier to identify outliers or data points that are significantly different from the average.
- It can provide a clearer picture of the overall trend of the data.
- It can make the chart more visually appealing and easier to understand.
Conclusion
Adding an average line to a bar chart is a simple and effective way to provide additional context and make it easier to draw conclusions from the data. By following the steps outlined in this article, you can easily add an average line to your own bar charts.
