So if your plot is displaying a one hour average the plot is generated every one hour, if it’s displaying a three hour average it is generated every three hours. If there is no aggregate involved the plot is generated every report cycle. The year plots (by default) use a one day (or 24 hour) aggregate interval so are generated every 24 hours. You can of course change the aggregate interval used in the plot to something much less, but this will increase (among other things) the time taken to generate the plot (more correctly it increases the time taken to obtain the data from the database).

Once the data is imported it is in the database and running reports and generating plots only reads the data from the database; it does not alter it. So re-importing achieves nothing. What I said is that the default settings used in the year plots will give you a uv plot that appears to have low values. This is because the default year plots mostly display the average daily value (some do not, eg rain). So for an observation like uv that typically peaks around midday and is zero at night the daily average is almost always substantially less than the daily maximum. What I did say was that you can force WeeWX to regenerate plots on the next report cycle by deleting the previously generated plots on your WeeWX machine. This saves you having to wait for the aggregate interval to pass (saving you having wait 24 hours to pass for a year plot to regenerate).
