Format your spreadsheet cells with Data Bars

You can format the cells on your spreadsheet so that they have bars in them, or even set up a range of numbers to have a colour scale. You can do all that with Conditional Formatting.

In the image below, we've formatted a set of sales figures so that the cells contain data bars:
