i created a dashboard using streamlit, pandas, and plotly. when i run the code in vs code, it displays the full dashboard with all the data. however, when i deploy it on streamlit share, the dashboard or some charts are not fully visible.
while plotting the line chart, is it default setting in streamlit that it takes the browser timezone information, even if the dataframe is in to different timezone.
Happy to help! Try this documentation: docs.streamlit.io/develop/tutorials/databases/postgresql If you still run into questions, please let us know on the forum! discuss.streamlit.io/

I like DataProfessor. I would like more videos from him:) Like this video)
Thanks Dmitry for the support :)
Streamlit ois indeed a powerfull tool !

what about how to use database to save data and retrieve
Does this support VPython? if so can you make a video about that
Good video on streamlit. Is it possible to drill down and drill across on a chart in streamlit? Grt if there is any document. Thanks
I suppose you could use the highcharts library?
Thanks a lot for this video. Could you please show how to deploy a Streamlit app that connects to a PostgreSQL database?

athane le code pour postgresql:
import streamlit as st

import matplotlib.pyplot as plt
# Connect to the PostgreSQL database
conn = psycopg2.connect(dbname="dbname", user="youruser", password="yourpassword", host="localhost")

cur.execute(f"SELECT * FROM {table}")
rows = cur.fetchall()
cur.close()
return rows
# Load data into a pandas DataFrame
rows = load_data(table)
df = pd.DataFrame(rows, columns=["country_id", "country"]) # Replace with actual column names
# Create a bar chart
plt.figure(figsize=(8, 6))
plt.bar(df["country_id"], df["country"])
plt.xlabel("X-axis label")
plt.ylabel("Y-axis label")
plt.title("Bar Chart")
st.pyplot(plt)
# Close the database connection
conn.close()
Considering recent events. It might be better to distance Streamlit from Snowflake.
