The difference is that in v8, there is LV_EVENT_DRAW_PART_BEGIN, so if I want to hook the process of drawing tick, I just need to refill the content of the buf in my callback, because the actual width of the text will be calculated later in the chart. But v9 is not like this...

LV_EVENT_DRAW_PART_BEGIN Start the drawing of a part. This is a good place to modify the draw descriptors (e.g.rect_dsc), or add masks. LV_EVENT_DRAW_PART_END Finish the drawing of a part. This is a good place to draw extra content on the part or remove masks added inLV_EVENT...
