Plot Description:

This autoplot prints out the top 10 dates for number of VTEC events issued. Note that a warning covering multiple counties would only count as 1 in this summary. You can either produce top 10 totals for a given wfo/state or get the top 10 totals per wfo/state over all wfos/states.

If you summarize by a 12z to 12z period, the date of the start of the period is shown. If you summarize over a multiple day period, the entire period must reside within any calendar date limit.

Autoplot 171 is similar to this app, but produces monthly heatmaps.
