😍 Adding an icon to a st.metric easily

[germancastano]

Hi,
This is a simple code I use in my dashboards for adding an icon to the st.metric component. These are some things you must have in mind:

• I use the stylable_container from the streamlit_extras. By the way, thank you to the authors, wonderful components .You must import this component to use this code.
• I use the Material Icons you can find here and you must use the code point, this is the code that looks like e8b6 but you must use it like this \e8b6

This is the code

def iconMetricContainer(key,iconUnicode,color='grey'):
    """Function that returns a CSS styled container for adding a Material Icon to a Streamlit st.metric value

    Args:
        key (str): Unique key for the component
        iconUnicode (str): Code point for a Material Icon, you can find them here https://fonts.google.com/icons. Sample \e8b6 
        color (str, optional): HTML Hex color value for the icon. Defaults to 'grey'.

    Returns:
        DeltaGenerator: A container object. Elements can be added to this container using either the 'with'
        notation or by calling methods directly on the returned object.
    """
    css_style=f'''                 
                    div[data-testid="stMetricValue"]>div::before
                    {{                            
                        font-family: "Material Icons";
                        content: "{iconUnicode}";
                        vertical-align: -20%;
                        color: {color};
                    }}                    
                    '''
    iconMetric=stylable_container(
                key=key,
                css_styles=css_style
            )
    return iconMetric

And this is how you can use it:

with utils.iconMetricContainer('metricMujeres','\e13e','#FF90BC'):
    st.metric(f'Mujeres','11.4%','-0.36% - Oct 31 2023',delta_color='inverse')

And this is the result:

I hope this helps you to give a better look to your dashboards, you can see how it looks in this dashboard

Please let me know if you have any questions, suggestions or corrections.

Thank you

Hi @germancastano

Amazing! This is a great code snippet for adding icons to st.metrics, thanks for sharing!

Hi @germancastano, just FYI - there’s an old post that shows another way you can create custom metrics (with icons), in case you are interested.

Style Column Metrics like the Documentation - Using Streamlit - Streamlit

Cheers

Thank you, I didn’t know this post, I’ll check it, awesome alternative, I think it would be great that Streamlit components allow adding CSS classes natively as a parameter so we could handle everything using only CSS.

Thanks for sharing
