How to Create a Thermometer 🌡️ Chart in Excel

In this article, you will learn how to create a chart that looks like a thermometer. For this type of graph, you will want to present data that shows the percentage of a value (e.g., the annual plan for the sale or use of the budget).

A thermometer chart, also known as a "gauge chart," is a type of chart in Microsoft Excel that represents a single value within a range of values, using a thermometer-style visual. The chart can be used to visually track a goal, such as a sales target, and compare it to actual results.

Data preparation

To create a thermometer goal chart in Excel, you need data. One cell should show the current value, and the second should be the target value. On this basis, calculate the percentage.
