How to Understand a Google Sheets Combo Chart

Having combo charts in your spreadsheet is nice, but it’s useless if you can’t interpret the data. Here’s a quick guide to understanding combo charts in Google Sheets.

Understand the Important Data Points

Understanding a chart requires understanding the context and key metrics. For example, if you use a combo chart to compare sales across teams, you need to understand how certain sales data relate to your workplace and your company’s strategic goals.

Examine the Pattern

Look at the bars and lines in the combo chart to understand the overall pattern. Record your highest and lowest score. Also consider adding best-fit lines to your charts to help identify trends in your data.

Identify Outliers

Observations that deviate from trends or patterns in the data are called outliers. Because these are idiosyncratic events, outliers can mislead decision makers. Finding outliers in your data is easy. Here is an example: Imagine that sales at your workplace or employer have increased over the past three years. However, it dropped by 70% in a month before returning to average sales. This singular event may have been caused by a pandemic or other extreme external factors.

In many cases this data can be ignored. Outliers in the chart can be identified because they are not near other data points in the combo chart.

Best Practices for a Combo Chart in Google Sheets

Bar vs. Column

Instead of using both columns and bars, choose to use one or the other. Notice the contrast between the two. The bar chart is horizontal. A column chart, on the other hand, has a vertical shape. Decisions should be made by the intended audience. Column charts are usually best used in conjunction with line charts or as histograms in Google Sheets.


The two Y-axes in the chart should be displayed using contrasting colors. Don’t forget to include a legend so your readers/viewers understand the importance of your data.

Avoid Clutter

As a visual data storyteller, you’ll definitely want to populate your Google Sheets Combo Chart with information. But remember, clutter may not get you the buy-in you want. Too many details can hide important lessons you want your audience to understand.
