● If there a no weather data in the defines time frame, Meteohub will throw an error or

will not show a graph.

2.8.2 Time Resolution

As explained before Meteophub computes time-compacted data from the raw weather data.

These time-compacted data is computed for different time scales: 5 minutes, 10 minutes,

30 minutes, 1 hour, 6 hours, 1 day, 1 month. If time frame and time resolution do not fit

nicely and produce more than 2000 data points to be used for graph generation, a warning

message is displayed that asks for reducing time resolution or reducing time frame. Graphs

with more than 2000 values for x-axis normally don't make sense and should be avoided as

they have a potential of overloading a Meteohub system.

When you define a weather graph you can choose with time scale should be used for the

graph. If you do produce a line graph you might choose a tight time scale to get a smooth

graph. If you want a bar graph, it might be more suitable to show values in a more stretched

time scale. For example, if you plan to show the minimum, average and maximum

temperature of each day of a month you will choose a time resolution of "1 day" and a time

frame of the month under consideration.

As there a some graphs just make sense with certain time resolutions, the choices might be

restricted.
