It is possible to hide white horizontal lines in column chart (the ones that appear when you set the interval on Y axis)?
I would like to have 3 lines instead: two threshold with different colors and one line which display the value.
You can do something like this:
index=_internal | eval min_threshold=3000 | eval max_threshold=7000 | timechart count(sourcetype) as sourcetype avg(min_threshold) as min_threshold avg(max_threshold) as max_threshold
Then, in the visualization options, set min_threshold and max_threshold as overlays. This will create a column chart with 2 lines.
