Refresh graph/datatable inside loop

Yes, it is possible, use st.empty to have the chart stay in place and be replaced with the newer image.
Here’s an example:

import streamlit as st
from PIL import Image
from time import sleep

pl = st.empty()
img1 = Image.open('img1.jpg')
pl.image(img1, use_column_width=True)
sleep (2)
img2 = Image.open('img2.jpg')
pl.image(img2, use_column_width=True)
