Values not matching in same Grafana dashboard

I'm facing an inconsistency in Grafana (bound to Zabbix). Screenshot below clearly shows min-mean-max values on the left panel and on the right ones are not the same ( ex min : 80.6ms vs 195 ms ). Data source is the same.

I noticed changing to shorter time span for whole dashboard may align values but I haven't found a pattern so far.

Any idea?

Issue was related to "Max data points" value in query options for that gauge panel which was (far) smaller the the timeline panel. Calculation were limited to less data, hence the difference.
