When running browser monitor checks there will be different types of results or reports depending on the type of monitor and your settings. However, some results may apply to a number of monitor types, e.g. the waterfall exists for Full Page Check monitors as well as transaction monitors.
With the Core Web Vitals and W3C navigation timings you have two sets of metrics that are based on international standards. The metrics allow you to better understand the performance of your website and find out what needs to be improved to score higher in search engine rankings.
The waterfall chart is a visualization of your monitoring results in a bar chart and shows in detail when page elements are loaded and how long it took. It is a good tool to do troubleshooting and find out what slows down the loading of a page. Check out the knowledge base articles about waterfalls:
The waterfall chart gives you a good insight into the loading of your page elements. However, it may be difficult to imagine what is happening there step-by-step. The timeline screenshots may help you to understand what the page looks like at different steps in the loading process.

This information is available in check results of transactions and Full Page Check monitors. You may have to switch on the feature, please check the knowledge base article below for details.
