this new block is finally a real “interactive/dynamic” graph. First you select parameter of choice and the number of data points to preload from db. This will show initally on your page. Then, using the API, it will dynamically be adding points in realtime, so the graph will be sort of “moving forward” as new data is sent by the API script.
In the DEMO I set the interval to 30 seconds and used wind speed, which probably best illustrates how this works because it changes very quickly. Works with both dark and light themes.
