Streamlit dashboards

Compose metrics, charts, and data into clean dashboard layouts.

Cards with borders

Use border=True to create visual cards. Supported on st.container, st.metric, st.columns, and st.form:

# Container card
with st.container(border=True):
    st.subheader("Sales Overview")
    st.line_chart(sales_data)

# Metric card
st.metric("Revenue", "$1.2M", "+12%", border=True)

# Column cards
for col in st.columns(3, border=True):
    with col:
        st.metric("Users", "1.2k")

Card labels

Add context to cards with headers or bold text:

# With subheader
with st.container(border=True):
    st.subheader("Monthly Trends")
    st.line_chart(data)

# With bold label
with st.container(border=True):
    st.markdown("**Top Products**")
    st.dataframe(top_products)

KPI rows

Use horizontal containers for responsive metric rows:

with st.container(horizontal=True):
    st.metric("Revenue", "$1.2M", "-7%", border=True)
    st.metric("Users", "762k", "+12%", border=True)
    st.metric("Orders", "1.4k", "+5%", border=True)

Horizontal containers wrap on smaller screens. Prefer them over st.columns for metric rows.

Metrics with sparklines

Add trend context with chart_data:

weekly_values = [700, 720, 715, 740, 762, 755, 780]

st.metric(
    "Active Users",
    "780k",
    "+3.2%",
    border=True,
    chart_data=weekly_values,
    chart_type="line",  # or "bar"
)

Sparklines show y-values only—use for evenly-spaced data like daily/weekly snapshots.

Dashboard layout

Combine cards into a dashboard:

# KPI row
with st.container(horizontal=True):
    st.metric("Revenue", "$1.2M", "-7%", border=True, chart_data=rev_trend, chart_type="line")
    st.metric("Users", "762k", "+12%", border=True, chart_data=user_trend, chart_type="line")
    st.metric("Orders", "1.4k", "+5%", border=True, chart_data=order_trend, chart_type="bar")

# Charts row
col1, col2 = st.columns(2)
with col1:
    with st.container(border=True):
        st.subheader("Revenue by Region")
        st.bar_chart(region_data, x="region", y="revenue")

with col2:
    with st.container(border=True):
        st.subheader("Monthly Trend")
        st.line_chart(monthly_data, x="month", y="value")

# Data table
with st.container(border=True):
    st.subheader("Recent Orders")
    st.dataframe(orders_df, hide_index=True)
