{"options":{"scales":{"xAxes":[{"type":"time","time":{"min":1572697299066}}]}}}
Agree, but if I also create a valid ui_control message (see above) I still see no change in the UI.
?
What types of changes are you looking for at this point?
Please provide your full flow again.
I looking for a easy way to change the X axis during the runtime,

With the flow you just provided, if you open the debug tab, what do you see?
No error. Just see the payload as above mentioned.
The question is not to fix the flow, it is more if the msg.ui_controll with the following payload should work
{"options":{"scales":{"xAxes":[{"type":"time","time":{"min":1572697299066}}]}}}
are you saying that when looking at the graph, if you change the "Chart Scaling" number, nothing changes?
If you want the ability to take a graph and drill down at a particular time, you might want to investigate Influx and Grafana.

Yes,

I already have a ELK instance running with all these feature. But i want to check if I find a solution to draw charts with variables X-axis (time)

Maybe you should update NR. (current release is 1.0.2) and the dashboard (current release is 2.17.1) - You could try updating the dashboard first via the pallette manager in the hamburger menu and use the script to update NR on the Pi.
BUT make sure to backup your flows first or even better, backup your SD card first.
I think versions you are using should do fine, but nothing bad if you can update.
Try this flow, minimum example. Inject the xaxis change and see if chart updates.

Updated the dashboard --> works fine 
Thx a lot!
Fine
Just downgraded the dashboard to 2.14 and can tell, it's not working.
But all good for now.

If i using this method, the msg.ui_control.ymax doesnĀ“t work anymore.
Is there a way to set x and y axis together?
optional with the locale time "DE-de" or setting like "HH:mm"?
Then i can reduce my Dashboard from 12h & 48h Diagramms to one Variable Line-Chart.
Here my Problem with Pictures
If i Zoom to 2h thereĀ“s no way to scale between 15 and 25 Degrees.
It uses the Zero point from the 22h Picture!

Excellent, that's what I was looking for.
Hi hotNipi and zenofmud,
thanks for the idea. I tried it and it is working.
But the format of the axis will be changed.
Do you have an idea with a dynamic x-axis with the original format?
