The Script and Step <metric> chart on the Charts tab of the test results screen shows one of the result metrics of each simulated test (UI or API) and their steps (a URL or synthetic step within a UI test, a request in an API test).
Here is a sample view of the chart:

By default, the chart shows the Net Duration metric. To select the metric to display, click on the top right of the chart.
The net execution time of a UI test or its step, in seconds. This values doesn’t include the Think Times of test events, that is —
The total execution time of a test (or test step) in seconds, including all the think time values.
The total time during the test run (or test step execution) that the browser spent waiting for the response from the server. This includes time periods spent on DNS resolving, setting up a connection to the tested server (if needed), processing redirects, and transferring data over the network.
3rd-Party Response Time
The response time taken for requests to domains different from the domain of the navigated URL. Examples of these third-party domains include Google Analytics, font storages, Facebook, weather info providers, and so on.
This value helps you understand how much time your pages spent on requesting third-party sites.
The sum of all Think Times in the UI test (or test step). This value doesn’t include non-blocking Think Times, that is, the Think Time values that didn’t cause pauses in the network activity (see below).
Non-Blocking Think Time
This metric is a sum of Think Time values that don’t pause the test playback.
A typical test has multiple think times in it. For example, a recorded UI test has Think Times for almost every recorded event. Depending on the length and location of these Think Times in the test, they might pause the test execution or not. For example, a Think Time at the beginning of the test step, most probably, doesn’t block the test run, because at this time the browser is still sending requests and loading resources requested by the current page. However, a long Think Time at the end of the test step will most likely pause the test run, because all the resources, most probably, have been downloaded and the test engine spends time idling.
