Using time aggregations

Dashboard time aggregations allow on-the-fly aggregation and resampling of underlying observation and forecast data. The default display is the "Latest" forecast. There are quick link buttons to show the forecasts over the last 3 and 10 day periods, in addition to the latest forecast. Users can change the date range displayed on the chart by adjusting the calendar dates in the top right of the chart. 

To change a visualization's time aggregation, use the drop-down. Available options differ depending on the visualization. In addition to hourly forecasts (default), 6-hourly and daily aggregations are also available. The active time aggregation transforms both the visualization and any data exported via CSV or viewed in the table.
