Plot Description:

The National Weather Service issues Local Storm Reports (LSRs) with a label associated with each report indicating the source of the report. This plot summarizes the number of reports received each year by each source type. The values are the ranks for that year with 1 indicating the largest. The values following the LSR event type in parenthesis are the raw LSR counts for that year. You need to graph at least two years worth of data to make this plot type work.
