Adjusting amount of rows to show in logs panel

Hi! I started using Loki and ran into difficulties with visualisation it in logs panel. I can adjust amount of rows in datasource and in logs panel (max datapoints parameter) for query but can’t for showing in panel. For my tasks i’d like to set 1500-2000 rows minimum and I understand that this can lead to some complications. I’am using Loki-stack by helm chart (2.3.0) and stanalone Grafana (7.2.1). Thank’s!
