Dashboards: MySQL User Details: user labels unreadable with high number (>20) of users

Due to Grafana Bar Gauge panel bug https://github.com/grafana/grafana/issues/17736  when items do not fit in the panel, labels get unreadable (e.g. for row fetched/read, rows updated) or is dashboard is drawn out of panel borders getting unreadable too (e.g. for Total Sessions panel)

We observe this issue with number of users above 20.
