Module:Weather/sandbox

Module documentation[view] [edit] [history] [purge]

This module can be used to display temperatures in a table. It is under development and is intended to be efficient so a page can hold many tables.

• Input numbers must use a hyphen if negative (Unicode minus "−" would give an error).
• All displayed numbers (including inputs) use Unicode minus if negative.
• The input consists of 13 values, separated by any number of spaces.
• Each of the 13 values must be a number. Any invalid value results in the corresponding cell being blank with no error message or tracking category.

The following functions are available:

Function	Input	Output
CtoF	°C	°C (°F)
FfromC	°C	°F (°C)
CfromF	°F	°C (°F)
FtoC	°F	°F (°C)

The following templates use the module:

• Template:Avg temp row C/sandbox
• Template:Avg temp row F/sandbox

An example using the above templates and the module is at:

• sandbox permalink

The output can be examined by entering the following example atSpecial:ExpandTemplates.The output from each of the following lines is identical.

{{#invoke:weather|CtoF|-10 -5 0 5 10 15 20 25 30 35 40 45 50}}
----
{{#invoke:weather|CfromF|14 23 32 41 50 59 68 77 86 95 104 113 122}}

Optional parameter

• |palette=name

  Wherenameis the built-in name of a palette:

  cool (default)

  cool2 (modified)

  cool2avg (modified and intended for average temperatures)

Testing

The functionshowprovides a way to test the color schemes. It generates a graph of how the red, green, and blue portions of the color vary with temperature, and a table of the full range of temperatures in °C.

Optional parameters

• Two unnamed parameters may be entered to specify the first and last Celsius temperatures (|-90|59by default).
• The palette can be specified with|palette=nameas above.

The following codes produce the same result:

• {{#invoke:weather|show}}
• {{#invoke:weather|show|palette=cool}}

This modified palette is intended for average temperatures. It results in good colors between the extreme highest average monthly temperature of +39 °C (102 °F) inDeath Valley,California, and −68 °C (−90 °F), the extreme lowest average monthly temperature atVostok Station,at a high elevation on the Antarctic ice sheet. These are the highest and lowest knownaveragetemperatures recorded on Earth, not to be confused with the highest and lowest records, which are quite a bit hotter and colder.
