Merhaba, api tarafından gelen verilerle grafik oluşturmaya çalışıyorum ancak api tamamlandıktan ve state güncellendikten sonra grafik oluşmuyor.Kodu tekrar save ettiğimde sayfa yenilemeden grafik güncelleniyor bu neden olabilir?

const [rootAll, setRootAll] = useState([]);
  const [state, setState] = useState([]);

  useEffect(() => {
    fetch("http://localhost.com/api/root/all/static")
      .then((res) => res.json())
      .then((result) => setRootAll(result));
  }, []);

  useEffect(() => {
    setState({
      options: {
        chart: {
          id: "apexchart",
        },
        xaxis: {
          categories: [
            "00:00",

Çözümü bulamadım component ilk render olduğunda boş array dönmekte bunu nasıl engelleyebilirim ? Çünkü fetch request sonrası kod save edildiğinde verileri grafiğe yansıyor ama ilk boş döndüğü için kontrolda sağlasam yinede işe yaramıyor
