What does -1M offset in Timelion translate to? Is it aware of calendar months or does it just translate to the number of days in the current month?
I have the Kibana time filter set to last month and the metric is a csum of a given field. I then chart -1M offset alongside the original chart which I was expecting to translate to the entire month of October and the last data point on the -1M chart shows a csum value which is not correct and different from a csum chart with the date filter set from October 1st to Oct 31st.
Can you clarify the expected behavior and how I can accomplish comparing / subtracting the csum of the entire month with that of it's previous month,
