Hi, I created a dashboard with streamlit, but the data that I use changes all days. How can I make that dashboard refresh automatically once a day?
How do you load your data in your streamlit dashboard? If you refresh your input data, it will update your dashboard accordingly.
Hi @Nicolas_Parra_Avila, welcome to the Streamlit forum!
Per @arnaud’s comment, we provide an example of doing this in the
streamlit hello demo:
import streamlit as st import time import numpy as np progress_bar = st.sidebar.progress(0) status_text = st.sidebar.empty() last_rows = np.random.randn(1, 1) chart = st.line_chart(last_rows) for i in range(1, 101): new_rows = last_rows[-1, :] + np.random.randn(5, 1).cumsum(axis=0) status_text.text("%i%% Complete" % i) chart.add_rows(new_rows) progress_bar.progress(i) last_rows = new_rows time.sleep(0.05) progress_bar.empty() # Streamlit widgets automatically run the script from top to bottom. Since # this button is not connected to any other logic, it just causes a plain # rerun. st.button("Re-run")
For once per day, you might pursue a different means for doing the sleep component, but this demo can hopefully get you on the right track.
Hi @randyzwitch, in your example st.button(“Re-run”),
- is that a visible button? and
- will the user need to click to re-run?
Yes, it is a visible button for the user to click to re-run the demo.
