As you can see the colour scale I use for temperature is dynamic rather than using a fixed set of colours as preferred by the BBCBBC The British Broadcasting Corporation (BBC) is the national broadcaster of the United Kingdom, based at Broadcasting House in London. It is the world's oldest national broadcaster, and the largest broadcaster in the world by number of employees, employing over 22,000 staff in total, of whom approximately 19,000 are in public-sector broadcasting. and UKMOUKMO The Meteorological Office is the United Kingdom's national weather service. It is an executive agency and trading fund of the Department for Business, Energy and Industrial Strategy. It may not be transferable and directly comparable to any other month, but I find it much easier to find the hot and cold spots, and I can easily switch back to a fixed scale in software if necessary.
