* Add limit type field selection * Take into account LimitType to generate SQL request for Line graph Also, add LimitType in default configuration for console * Take into account LimitType to generate SQL request for Sankey graph * Refactor on SQL query used by line and sankey * Add limitType description in doc * Order by max in graphLine when limitType max is used * Fix query when using top max Revert some modifications, as they were no longer relevant with the query fixed. * Rework way to sort by max in line graph type * Add configuration validation on LimitType --------- Co-authored-by: Dimitri Baudrier <github.52grm@simplelogin.com>
