Another option is to filter out the duplicate rows in the data during query. The arg_max() aggregated function can be used to filter out the duplicate records and return the last record based on the timestamp (or another column).Here we use a value of 0, which is the least accurate but fastest.As with dcount we can use values 0 to 4 to get the best balance of speed and accuracy for our needs.

It is your KQL query that has to be modified. The key to getting your time-series charts right is to fetch all the time and metric information in the result set from your query.

See examples of union withsource, union with let, and union with queries.This issue is a placeholder for adding support directly in KQL for fuzzy queries. The syntax may not remain the same, but the concept & functionality would. Add a fuzzy operator (similar to Lucene's ~) to KQL. This would allow also using fuzzy search in KQL, which is currently a more common use-case to still switch back to Lucene.
