How to update the chart series using mouse to change value dynamically?

[tjstyle]

Sorry to bump old topic, but there are any update for dragging point function?
I also was create a thread long time ago but no reply so far here:

Drag point in Chart

Hi All, Any lv_chart features that are similar to the screenshot below? [chart] So the chart is can be directly changed when the point is dragged. From what I see in the latest documentation, the nearest features is this: Show cursor on the clicked point Except it can’t be directly changed nor dragged. Any suggestions are appreciated! Regards, TJ.
