Resolution of Custom charts

When using a Custom chart block the available duration and Resolutions confuses me a bit.
Selection shows:
5 min, 1 sec: (300 datapoints)
15 min, 1 sec: 900
30 min, 10 sec: 180
60 min, 10 sec: 360
3 h, 30 sec: 360
6 h, 30 sec: 720
12 h, 1 min: 720

Shouldn’t they all be able to show 900 ?

@Lars_Andersson,

We have a stock set of resolution choices cross all the dashboard blocks. Thee only resolution choices you see for a specific duration have fewer than 1,000 points and at least 1 point.

We also don’t make new resolutions to get as close as possible to 1,000 data points.

Thank you,
Heath
