制作温度仪表

    
使用带有单位的温度计给出不同城市的温度：
Wolfram Language code: cities = {"Cairo", "Fairbanks", "Tangiers", "Moscow", "Chicago", "Miami", "Sydney", "London"};
Wolfram Language code: citytemps = WeatherData[#, "Temperature"]& /@ cities;
Wolfram Language code: Row[MapThread[ThermometerGauge[Quantity[#, "Celsius"], Quantity[ {-25, 40}, "Celsius"], GaugeFrameStyle -> None, GaugeLabels -> {"Unit", Placed[#2, Top]}] &, {citytemps, cities}]]
