You can do it by using a bg_img.

I had a mouse cursor icon in my project so I used that as an example :slight_smile:


    LV_IMG_DECLARE(mouse_cursor_icon);
    lv_obj_set_style_bg_img_src(chart, &mouse_cursor_icon, LV_PART_INDICATOR);
    lv_obj_set_style_size(chart, 20, 20, LV_PART_INDICATOR);   /*Be sure the point is large enough for the image*/
    lv_obj_set_style_bg_opa(chart, 0, LV_PART_INDICATOR);  /*Make the background transparent*/
