Radar style ** solved **

Hi,

What exactly does \"Aggregation of Sensor Data into Time Buckets of\" ?
If I say 5 min what differs from 1 day when I am trying to display wind for the last 24 hours?

I thought saying 5 minutes aggregation it should be a more disperse graph than saying 1 day aggregation, but it appears just the opposite :S

Hi,

that seems to be the bug/future/missunderstanding function (??) i've reportet a few weeks ago - but without some screen shots like yours. May be a solution will be found now with your pictures.

Hi,
I inspected the code to understand what happens here. Meteohub takes the first set of aggregated data it finds that is in the specified time frame. This data set is then displayed.

As a result Chiil's 5 min bucket graph just shows the wind distribution of 5 minutes (starting 24h ago). The 1 hour bucket graph displays wind distribution during an hour (starting 24 hours ago) and the 1 day bukcet shows wind distrubution of the whole day.

So the time frame just gives the starting point, while the time resolution determines how long the period is.

This behavior is a bit different from the other graphs, where the time period is determined by the specified time frame and the time resolution just tells how many data point are used for drawing.

So the time _frame_ just gives the starting point, while the time resolution determines how long the period is.

Thanks for the answer, now I understand it!

But, would it be a better option to change caption to \"Observation Frame\" or similar, instead of Time Resolution?

This is a special behavior on radar charts. In the other graph types the time frame specified by start/end date is used and the time resolution just tells granularity of data to pick for building the graph.
