If you change the options to, say see 'Most common problems in the past year', the frequency column shows "Loading..." (in pretty small text). However, the graphs and all the data are retained.

Once the user has changed a setting, I think the existing data should be immediately removed or greyed out or something to denote the new query has not yet completed.

Also note that if an error occurs ("An error occurred while trying to load the most common problems."), the existing data is still retained so users may be misled into thinking the data they are viewing refers to the time range they selected.
