Hello,

This code does not work, neither ymax, xmin nor label are changed.  
What is the correct solution?

Welcome to the forum @lbarjak

Feed the function into a debug node set to Output Complete Message and show us what it says.

I don't think the chart accepts dynamic properties for those values (not yet anyway). I don't see it mentioned in the node's help text or the [documentation](https://dashboard.flowfuse.com/nodes/widgets/ui-chart.html).

No indeed nothing in the code of the ui-chart node to support dynamic properties.

Personally I wouldn't add to much new features to the ui-chart node now, because that will make it even more difficult to migrate from ChartJs to Echarts (see this [issue](https://github.com/FlowFuse/node-red-dashboard/issues/782)). Even now, such a refactoring will be not an easy job...

It is always worth checking the docs when something doesn't work as expected.

As a last resort, yes.

Has it occurred to you that by asking here rather than checking the docs yourself you wasted my time checking the docs for you and @BartButenaers' time checking the code?

My conclusion:  
I have had good experience with the svgjs library in other areas, so I will use it for the diagrams.
