Going clockwise, the dwell-time page has the following UI elements
Select type: allows you to switch between showing the average dwell time (bar charts) or individual dwell times (table).
One/Two time periods toggle: toggle between analyzing a single time period, or doing side-by-side comparisons of 2 different periods. Two periods is only supported for average dwell time analysis.
Sync properties toggle: when working with 2 time periods, the default is to use the same dataset/filter combination for both time periods. For example when you change the filter in the UI, the filter will be updated for both time periods.
By disabling the checkbox, you can use different filters or even different datasets for the 2 time periods.
Select time period: this button determines what the UI elements below control.
For example, when Period 1 is selected, and you adjust the filter in the UI, this will affect the filter for period 1 and not the filter for period 2 (unless the sync properties checkbox is checked).
Select data set: when your project contains multiple datasets, there is a dropdown to select the dataset (not shown in the screenshot).
Time period customizer: choose which time period to use for the dwell time calculations.
Attribute filters: you can filter the records that are used to calculate the dwell time. For example, it allows to only analyze the dwell time of the status property "Cargo vessels" and "Fishing boats" instead of all vessels.
You can filter on properties in your data.
Timezone selector: select in which timezone you want to see the results displayed.
Areas of interest selector: choose the areas to include in the analysis. Each of the selected areas will be used to compute the average dwell time for, or to detect assets that enter and exit the area.
The areas you can choose from are obtained from the areas of interest included in your project, as well as the areas you have drawn on the spatial map of the visual analytics page using the map controllers.
Widget pop-up menu: shows a pop-up menu with additional options:
