But the view is static to change the range you need to leverage buttons again. Dygraphs allows dynamic range adjustments and also moving the mouse over the graph and showing the graph values in a small window and so on. This is much more dynamic and would create a higher user experience as it is currently likewise available in Apples Homekit.
But it is a great first step to find out how to create a graph with Dygraphs from the persistent data and import it as a dynamic image into the sitemap. I will try to achieve this in a first approach
So, thank you very much for guiding me to your tutorial
I am still of the opinion that the default chart items looks a bit “old-fashioned” and that a lean, modern style and view of the charts would create a modern look and a much better user experience for openHAB like the Basic UI does compared to the Comet Visu view which is the “old” iPhone style.
I would like to understand if there is some interest to modernize the view or if every one should create his individual look.
