How can global companies like Apple and Google utilize thermometer charts to compare their actual revenue and target revenue?

While the content does not provide a specific real-world example of a company using a thermometer chart, it's common for many businesses to use such charts to visualize their performance. For instance, a company might use a thermometer chart to track its annual sales performance against its targets. The chart would show the target as the full thermometer and the actual sales as the filled portion. This provides a clear, visual representation of how close the company is to meeting its sales targets. However, without specific examples in the content, it's difficult to provide a more detailed answer.

Some alternative methods to thermometer charts for visualizing the comparison between actual and target revenue include bullet charts, bar charts, and line graphs. Bullet charts are particularly useful as they can display multiple measures at once, including the target value and actual value. Bar charts can also be used to compare actual and target revenue by representing each as a separate bar. Line graphs can show trends over time, which can be useful for tracking revenue targets.
