In this tutorial blog, you will learn about speedometer and how to create one for your data set using Microsoft Excel and Spreadsheet.
Introduction to Speedometer Chart
When it comes to present data in an understandable way in Excel, charts standout there. And there are few charts which are specific and can be used to present a specific kind of data.
An Excel SPEEDOMETER Chart is just like a speedometer with a needle which tells you a number by pointing it out on the gauge and that needle moves when there is a change in the data. It’s a single-point chart which helps you to track a single data point against its target.

Steps to Create a SPEEDOMETER in Excel
Here are the steps to create a SPEEDOMETER [Gauge] in Excel which you need to follow.
As we said, we need to insert two Doughnut charts and a Pie chart but before you start to create a SPEEDOMETER, you need to arrange data for it.
In the below worksheet, we have three different data tables (two for doughnut charts and one for the pie chart).
The first data table is to create the category range for the final SPEEDOMETER which will help you to understand the performance level.
The second data table is for creating labels ranging from 0 to 100. You can change it if you want to have a different range.
And in the third data table, we have three values which we will use create the pie chart for the needle. The pointer value is the real value which you want to track.
To create a SPEEDOMETER in Excel, you can use the below steps:
- First of all, go to Insert Tab ➜ Charts ➜ Doughnut Chart (with this you’ll get a blank chart).
- Now, right-click on the chart and then click on “Select Data”.
- In the “Select Data” window, click on “Legend Entries” and enter “Category” in the name input bar. After that, select the “Value” column from the first data table.
- Once you click OK, you’ll have a doughnut chart just like below.
- From here the next thing is to change the angle of the chart and for this right click on the chart and then click on “Format Data Series”.
- In “Format Data Series”, enter 270° in “Angle of first slice” and hit enter.
- After this, you need to hide below half of the chart. For this, click on only that part of the chart and open “Format Data Point” and select “No Fill”.
- For the rest of the fours data points, I’ve used fours different colors (Red, Yellow, Blue, and Green). At this point, you’ll have a chart like below and the next thing is to create the second doughnut chart to add labels.
- Now, right-click on the chart and then click on “Select Data”.
- In “Select Data Source” window click on “Add” to enter a new “Legend Entries” and select “Values” column from the second data table.
- Once you click OK, you’ll have a doughnut chart just like below.
- Again you need to hide below half of the chart by using “No Fill” for color and I’ve also added a color scheme for the labels. After this, you’ll have a chart like below. Now, the next thing is to create a pie chart with a third data table to add the needle.
- For this, right click on the chart and then click on “Select data”.
- In “Select Data Source” window click on “Add” to enter a new “Legend Entries” and select “Values” column from the third data table.
- After that, select the chart and go to Chart Tools ➜ Design Tabs ➜ Change Chart Type.
- In “Change Chart Type” window, select pie chart for “Pointer” and click OK
- At this point, you have a chart like below. Note: If after selecting a pie chart if the angel is not correct (there is a chance) make sure to change it to 270.
- Now, select both of the large data parts of the chart and apply no fill color to them to hide them.
- After this, you’ll only have the small part left in the pie chart which will be our needle for the SPEEDOMETER.
- Next, you need to make this needle bit out from the chart so that it can be identified easily.
- For this, select the needle and right click on it and then click on “Format Data Point”.
- In “Format Data Point”, go to “Series Options” and add 5% in “Point Exploration”. At his point, you have a ready to use SPEEDOMETER (like below), just a final touch is required and that final thing is adding data labels and we need to do this one by one for all the three charts.
- First of all, select the category chart and add data labels by Right Click ➜ Add Data Labels ➜ Add Data Labels.
- Now, select the data labels and open “Format Data Label” and after that click on “Values from Cells”.
- From here, select the performance label from the first data table and then untick “Values”.
- After that, select the label chart and do the same with it by adding labels from the second data table.
- And at last, you need to add a custom data label for the needle (That’s the most important part).
- For this, insert a text box and select it and then in the formula bar enter “=” and select the pointer values cell, hit ENTER.
- In the end, you need to move all data labels to end corners, like below:
Hurry! your First Gauge/SPEEDOMETER chart is ready to rock.
SPEEDOMETER – When to use it ?
I have listed some of the points which can help you to decide when you can this chart and when you need to avoid it.
1. Single Data Point Tracking
As we know, using a SPEEDOMETER can only be relevant (like Customer Satisfaction Rate) when you need to track a single data point.
So if you need to track data (like Sales, Production) where you have more than one point then there is no way for it.
2. Only Current Period Data
This is another important point which you need to take care while choosing a SPEEDOMETER for your dashboard or KPI reports that you can only present current data in it.
For example, if you are using it to present customer satisfaction rate then you can only show the current rate.
3. Easy to Understand but Time-Consuming While Creating
As I said, a SPEEDOMETER is a single data point chart so it’s pretty much focused and can be easily understandable by the user.
But you need to spend a couple of minutes to create as it’s not there in Excel by default.
