I created a grafana histogram using mysql. While it creates the histogram with different metrics I used in my query, I only see the largest bar chart being displayed and the rest of the metrics seem to be hidden unless I hover over the bar chart. Stacked graph works fine, but unstacked doesn’t. Is this an issue or am I using it incorrectly ? All other parameters being the same, I attached 2 images , one with stacked selected and one without it.
