iam using grafana for some weeks now and really like it, but one thing i can not figure out:
Iam writing data of the last years to an InfluxDB database. This data i want to visualize with bars and each bar should represent the sum of a field, grouped by a certain time intervall. The problem is that those intervalls dont share the same length, e.g.:
intervall 1 = 01.01.2017 - 15.01.2017 (15 days)
intervall 2 = 16.01.2017 - 04.02.2017 (19 days)
intervall 3 = 05.02.2017 - 21.02.2017 (16 days)
Some intervalls are notably longer then others so its very important for me to see this by the width of the bar.
What i did was converting the dates i have to unix time and adding them to my queue e.g.:
[…] WHERE time>=1508709600000000000 AND time<1511132400000000000 […]
With that approach the chart looks like this:
The bars start at the right position but they are drawn infinitely.
What i want to achieve is:
(i made that in paint)
I also tried to give the values in each time intervall a common tag and group by that tag, but then the bar for each tag is infinitely long in both positive and negative x-axis direction.
Maybe one of you guys got an idea and can help me with that one or got a tip what i might try next.
thanks in advance
