st.column_config.BarChartColumn

Configure a bar chart column in st.dataframe or st.data_editor.

Cells need to contain a list of numbers. Chart columns are not editable at the moment. This command needs to be used in the column_config parameter of st.dataframe or st.data_editor.

Function signature[source]

st.column_config.BarChartColumn(label=None, *, width=None, help=None, pinned=None, y_min=None, y_max=None)

Parameters

label (str or None)

The label shown at the top of the column. If this is None (default), the column name is used.

width ("small", "medium", "large", or None)

The display width of the column. If this is None (default), the column will be sized to fit the cell contents. Otherwise, this can be one of the following:

  • "small": 75px wide
  • "medium": 200px wide
  • "large": 400px wide

help (str or None)

An optional tooltip that gets displayed when hovering over the column label. If this is None (default), no tooltip is displayed.

pinned (bool or None)

Whether the column is pinned. A pinned column will stay visible on the left side no matter where the user scrolls. If this is None (default), Streamlit will decide: index columns are pinned, and data columns are not pinned.

y_min (int, float, or None)

The minimum value on the y-axis for all cells in the column. If this is None (default), every cell will use the minimum of its data.

y_max (int, float, or None)

The maximum value on the y-axis for all cells in the column. If this is None (default), every cell will use the maximum of its data.

Examples

import pandas as pd
import streamlit as st

data_df = pd.DataFrame(
    {
        "sales": [
            [0, 4, 26, 80, 100, 40],
            [80, 20, 80, 35, 40, 100],
            [10, 20, 80, 80, 70, 0],
            [10, 100, 20, 100, 30, 100],
        ],
    }
)

st.data_editor(
    data_df,
    column_config={
        "sales": st.column_config.BarChartColumn(
            "Sales (last 6 months)",
            help="The sales volume in the last 6 months",
            y_min=0,
            y_max=100,
        ),
    },
    hide_index=True,
