Gauges, how to remove the round center part

Is there any way to remove the round center part of the needle? I’m using a needle image and it all works fine, but that round part ruins it all. I’ve searched the lv_gauge in LVGL documents but there doesn’t seem to be any way to remove it? I hope im wrong.


It can be achieved by the following way.

lv_obj_t *gauge = lv_gauge_create(lv_scr_act(), NULL);

lv_style_t style_needle;
lv_style_set_size(&style_needle, LV_STATE_DEFAULT, 0);
lv_obj_add_style(gauge, LV_GAUGE_PART_NEEDLE, &style_needle);
