Date Parameters	FromDate: Select the option to specify the start date from which data is available from the source. ToDate: Select the option to specify the end date until which data is available from the source. The supported Datetime format is yyyy-mm-dd hh:mm:ss. To enable Chunks and Realtime options, in the Parameter Value Configuration pop-up the Time filter parameter must be selected for both FromDate and ToDate fields. Chunks To load huge volume of data in real time, the high frequency data loading option is available. This enables to split the data into smaller chunk of duration and update the data in the dashboard, avoiding the performance issue that will be caused due to the huge data. Enable the Chunks option and configure the following: Interval Seconds: Enter the frequency or the time interval at which the data needs to be loaded. Unit: Enter the unit used to divide the interval, which determines how the chart values are calculated. Time: Select the type (Day, Hour, Minute, Second) for the entered time interval from the dropdown. Example: If the date range is from 08:00:00 to 12:00:00 and the interval is 5 seconds, enabling the chunk option with a 10-minute interval updates the dashboard every 10 minutes. By the end of 4 hours, all 24 data chunks are displayed in the dashboard. The widget-level time filter takes priority over the dashboard-level filter when both are applied. Realtime To update your dashboard with realtime incremental data updated as per the defined interval. Enable the radio button to activate incremental data. Interval and Duration options are available. Interval is the frequency on how often you search the realtime data and Duration is the timeframe of the data captured. Enter the unit of time in the text box and select the time (seconds, minutes, hours, days, etc) from the dropdown list. Chunks and Realtime options are available only for timeseries type of data source only after you enable the Time Filter option under Properties.
