Time trend chart
The time trend chart, located below the map, is a line chart that plots the selected time range on the x axis against the:
- density of data points (for categorical data)
- average or total (for continuous numeric data; see Viewing time trends for continuous numeric data)
The time trend displays data based on:
- the data layer selected
- the map location selected
- any property filters or time-of-day filtering applied
When you change the time range displayed on the chart by either scrolling (to increase or decrease the time range) or dragging (to move the selection forward or backward), the data points on the map update, as well as the property statistics.
The drop down list indicates which data layer's time trend chart is being displayed and depending on your dataset description, the other layers that you can show.
Fitting all events into a range
After applying filters and selecting an area of the map, you may find that your data points are clustered in a small time frame:
To focus on these data points, you can use the Fit all events in range button
The chart adjusts so the time range starts with the first event and finishes with the last event:
Changing the start and end date of the time trend
As you change the start and end dates, the property values (to the left of the map) and the points on the map update dynamically. You can change the time range by:
- scrolling or dragging the time trend chart
- editing the start and end timestamps
Removing a time range filter
To remove a time range filter, in the filter bar, click the cross next the time range.
Note RESET ALL removes all the filters you have applied.
If you want to view the either the average or the total for a continuous numeric property on a time series chart, click the property's time series button on the palette, located next to the total / average value.
