#Warmer Days - Plotting the number of days with a temperature higher than 25 °C as stacked column in classes of 5 degree width #Heatmap - Showing a heatmap chart for all data available Below you will find an example image of each chart and an explanation of the origin of the numbers. For the calculations the standard C# LINQ-functions Min, Max and Avg are used. For the standard deviation this [https://stackoverflow.com/questions/2253874/standard-deviation-in-linq LINQ-extension] is used with a modification for a minimum number of observations required of 2, if less the StdDev returns 0 (zero). == Monthly Temperature == == Warmer Days == [[File:Warmer Days.jpg\|thumb\|right\|Warmer Days]] This chart ~~show~~shows a stacked column per year showing the number of days with a temperature larger than or equal to 25 °C. If the user use Fahrenheit, the boundaries are converted to the equivalent value in Fahrenheit, so 25 °C becomes automatically 77 °F. The classes used are 25-30 °C, 30-35 °C, 35-40 °C and 40+ °C. If climate changes faster then we think, another class will be added. The colours of this chart are hardcoded and cannot be changed. Moving the mouse around in the column sections provides the specific values in the tooltips. == Frost Days == [[File:Frost days.png\|thumb\|right\|alt=Frost days\|Frost days]] This chart shows a stacked column per year showing the number of frost days (with a temperature less than 0 °C (32 Fahrenheit) but the maximum is above 0 °C) and the number of ice days (where the maximum temperature is below zero (or 32 Fahrenheit)) If the user uses Fahrenheit, the boundaries are converted to the equivalent value in Fahrenheit, so 0 °C becomes automatically 32 °F. The colours of this chart are hardcoded and cannot be changed. Moving the mouse around in the column sections provides the specific values in the tooltips. === The info button === A Frost Day is defined as a day where the minimum temperature is below zero (or 32 Fahrenheit) but the maximum is above zero. An Ice Day is defined as a day where the maximum temperature is below zero (or 32 Fahrenheit) == Heatmap ==
