Automated Data Plotter

This application dynamically generates many types of graphs. These graphs are derived from processing of various data sources done by the IEM. Please feel free to use these generated graphics in whatever way you wish. Reset App. The IEM Explorer application offers a simplified frontend to some of these autoplots.

Plot Description:

This app generates a map showing either an explicit year's first or last date or the given percentile (observed frequency) date over all available years of a given temperature threshold. Sadly, this app can only plot one state's worth of data at a time. If a given year failed to meet the given threshold, it is not included on the plot nor with the computed percentiles.

Description of Observed Frequency: If requested, this app will generate a plot showing the date of a given percentile for the first/last temperature exceedance. As a practical example of the 50th percentile, the date plotted means that 50% of the previous years on record experienced that temperature threshold by the given date.

Based on a sampling of recent timings for this application, plot generation time has averaged 6 seconds. Hold on for the plot is generating now!
