Message type use for emitting time series data in LWC and fetch responses.
Value parameters
data
Data for the time series.
end
End time for the data.
groupByKeys
The final keys used for grouping the result. The value will be an empty list if the expression is not grouped. For multi-level group by this will be the final grouping used for the result.
id
Identifier for the time series. This can be used to stitch together messages for the same time series over time. For example in a streaming use-case you get one message per interval for each time series. To get all of the message for a given time series group by this id.
label
Label associated with the time series. This is either the auto-generated string based on the expression or the value specified by the legend.
query
Expression for the time series. Note, the same expression can result in many time series when using group by. For matching the data for a particular time series the id field should be used.
start
Start time for the data.
step
Time interval between data points.
styleMetadata
Metadata for presentation details related to how to render the line.
tags
Tags associated with the final expression result. This is the set of exact matches from the query plus any keys used in the group by clause.
Encode this object as JSON. By default it will just use Json.encode. This method can be overridden to customize the format or to provide a more performance implementation. When using a custom format, the subclass should also override hasCustomEncoding to return true. This will cause Json.encode to use the custom implementation rather than the default serializer for the type.
