Settings records by year

Waterloo set a daily record precipitation total on Monday with 1.81 inches reported. This
beat the previous record of 1.08 inches set back in 2007. The featured chart looks the
number of daily records set each year for the site. The totals shown are counted as time
progresses and not the present day totaling of which year holds the current daily records.
The black line on the chart is a simple model denoting 365/n, where n is the sequential year
number. For example, in 1893 there was no daily records so each day set a record! Then
the next year, one would expect to set records on roughly half of the days (365/2). The title
on each plot shows the long term average number of records set per year. Interestingly, the
values for daily high and precipitation are close together with the low temperature number
lagging by about 10%. Will likely look more into this difference in upcoming daily features.
