1 year ago I also have a use case for this. I'm measuring engine data, which fluctuates in a range. The recent high and low values are important.
I'm already measuring them, and they're available in my JSON, I just need somewhere to put it. I'd be using it with both linear and radial gauges. The pointer in the OPs image would be perfect, but have two to use.
For the time being, I've added text below each graph, with Min/Avg/Max. Text is "good enough", but so was running with no graphs. I'd like it to be prettier. :) It's refreshing all the data every 100ms, so markers on the graph will be easier than trying to read the text.
I had thought that an alternative may be to allow more than one needle/pointer per gauge. I don't know how user friendly that would be. But a blue/low and red/high needle showing the recent extremes could be good.
No bug report, everything is just awesome. Can't get enough of looking at my KPIs shown by these beautiful gauges!!!
Just one tiny wish, maybe it'll come true? It would be great to add custom markers to the scales (that are also bound to dynamic data and might move). So let's say to stay with the speedometer sample, it might mark the current speed limit. My concrete use case would be to mark a current dynamic "state of charge" limitation for a battery (computed by some battery charging control). So it might be limited to e.g. 60% SoC at the moment, but this limit does change or go away completely (so marker should not be shown if e.g. == min value). See below sample -- should be w/o much "visual noise" of course.
