This widget will display the weather forecast as a chart (meteogram) from the great meteograms.com website with extensive configuration options.
The available options are taken from the document attached here: https://trello.com/c/dS5TWiZ0/229-customising-the-meteogram-web-app
Some of them don’t seem to work (fonts and colors mostly), and there seem to be a lot more. I can’t provide support for those options, only copied them from the document. One way of customizing the meteogram further is to install the Android app - there are hundreds of settings to play with in it. There is a function to save the settings in a JSON file which you’ll have to host somewhere (on a publicly available server, for instance attaching them to your posts here should work!) and fill in the “Settings URL” option of this widget.
There are a number of examples with the JSON files attached in the Settings showcase Trello board at: https://trello.com/b/ST1CuBEm/meteogram-weather-charts
You can try them out, just copy the JSON file URL and paste it as the “Settings URL”.
Unfortunately you have to specify a fixed size in pixels for the meteogram for now, since the widget dimensions can’t be retrieved (yet).
Edit: an API token is now required for this widget to work - please email @drmrbrewer at firstname.lastname@example.org to get one and paste it in the widget’s settings! Thanks to @kjunker for the updated widget
