How to add Sparkline data visualization to Google spread sheets?


I like using spark lines data viz when it makes sense! It’s a great way to visualize trends in the data without taking too much space. Now, I knew how to add sparklines in Excel but recently, I wanted to use that on Google sheet and I had to figure it out so here are my notes:

1. Google has an inbuilt function called “SPARKLINE” to do this.

2. Sample usage: =SPARKLINE(B2:G2) — by default you can put line chart in your cells.

3. Then there are other options including changing the chart type. You can find them documented here:

4. One of the best practices that I advocate when you spark-line to “compare” trends is to make sure that you have the consistent axis definition. So the sample usage for that could like this:


(if you want to do this for excel then here’s the post: )

After you’re done, here’s what a finished version could like on Google sheet:

Here’s the working google sheet:

How to assign same axis values to a group of spark-lines in Excel?


Spark-line is a very handy data visualization technique! It’s great when you are space constrained to show trends among multiple data points.

Here’s an example:

But there’s an issue with above chart! Axis values for these group of spark-lines do not seem match – it could throw someone off if they didn’t pay close attention. So a good practice – when you know users are going to compare segments based on the spark-lines – is to assign them same axis values so it’s easier to compare. Here’s the modified version:

Excel Sparkline data visualization same axis

And…here are the steps:

1. Make sure that spark-lines are grouped.

Select the spark-lines > go to toolbar > Sparkline Tools > Design > Group

Excel Sparkline Group

2. On the “group” section, you’ll also find the “Axis” option – select that and make sure that “same for all axis” is selected for Vertical axis minimum and maximum values:

That’s about it. Just a quick formatting option that makes your spark-lines much more effective!
