Data manipulation settings used for default series.
Prepare displaying value after data aggregation.
aggregated value that is about to be displayed
time display unit time stamp in ms
the value to display.
Aggregation function to use. Used when data source does not provide data in needed display unit.
Note that when
avg is used, you should provide
countIndex so that
the calculation is correct even across multiple units.
- "max-threshold" modes finds the largest value that is at least X% of the data range; otherwise finds the minimum. X% is set with the 'percentile' setting.
- min - threshold
- max - threshold
- count - counts non-null values. If
countIndexis specified, uses that number for each value, otherwise counts each value as 1.
Index in the value array where the count of aggregated values are located. This is optional but should be provided if the aggregation
avg (average) and URL or
dataFunction is used to aggregate the values external to the chart because otherwise the chart will
aggregate values by simply counting them. So if
countIndex is not provided and there are values:
[[May 1 2014, 5], [May 2 2014, 15], [June 1 2014, 20]] the aggregation to year 2014 will yield
(5+15+20)/3 = 13.3 when the display unit is
((5+15)/2 + 20)/2 = 15 when the display unit is months.
Index in value the array where the values that will be aggregated are located. An alternative is to use
Method used to fill in time intervals that have no data. Used only for line series.Valid values:
- join - links data points with straight line
- skip - do not draw in this interval.
- zero - draw as the value is zero.
Controls the percentile level for percentile and threshold aggregation modes.
Data source to use if multiple data sources are available.
Retrieves the individual value used for calculations from the data array. This is an alternative for specifying
value to pass to aggregation
