Highlight High and Low Points in an Excel Chart Dynamically

Creating a chart is an easy task. Effective communication however, is an art. This technique will help you create professional charts in Excel by showing you how you can dynamically highlight high and low points in an Excel chart, in a way that it responds to changes in the data – without doing it manually!

Steps to Highlight High and Low Points in an Excel Column Chart

To draw an interesting story out of your data, you need to know some tricks to either cleverly label data on a chart or highlight data points in a chart. There are many techniques that would help you to make professional looking charts in Excel.

In today’s article, we’ll see how to highlight the high and low data points in an Excel chart.

We’ll follow these steps:

  • Get your data in place

    To highlight the high and low points on the column chart, we need to generate two extra columns of data -one for highest value and the other for the lowest value.

    The formula used for the minimum column is equally the same with the one shown for the maximum column below. The only difference is that instead of MAX you’ll replace with MIN

    In normal circumstances, Excel charts do not display error values. We’re therefore introducing the errors here to be able to hide the series, apart from where we have a value corresponding to either the maximum or minimum.

  • Insert a 2D clustered column chart

    Select the entire data set and from Insert menu, add a clustered 2D column chart

  • Format the series to overlap 100%

    Right click on one of the series, choose¬†Format Data Series… On the formatting options, change the overlap to 100%, reduce gap width to say 80%, and change the colours accordingly

        • Fill -choose Solid fill >>>White colour
        • Marker Options -check Built-in and increase the size of the icon to 11 or so points
    4. Repeat steps 1 to 3 above for the minimum series
