The chart with the faded area line cannot display the value pop-up when pressing a point? about lvgl HOT 5 CLOSED

Most probably the issue is that buf is local and if multiple draw_tasks are executed in the event LVGL adds them to a list, and when the rectangle will be drawn later, buf will be already lost.

I suggest using a rectangle drawing followed by a label drawing and set draw_label_dsc->text_local = 1 to make LVGL store a copy of the buffer.

(lv_example_chart_3 should be update too. )
