This is an app for the Android platform that takes weather data, from any one of a number of different sources including the excellent Norwegian Meteorological Office, and plots it using Highcharts. As well as weather data, you can also display tidal data, wave data, sun/moon elevation data, and much more besides. The meteogram chart can be displayed as a "widget" directly on the device's home screen, updating on a regular schedule, or via an "app" which provides an interactive (clickable) interface. Two different mechanisms are used: (a) server-generated charts; and (b) device-generated charts. Both mechanisms can be used to generate content for a "widget", while the latter mechanism is used for the "app" content.
