How do you get Plotly to adjust plot size based on screen resolution in a Streamlit app?

Question

I'm building a streamlit app with plotly graphs. However, I'm finding it hard to set a dynamic plot width in the plotly figures (I expect the app to be viewed in multiple resolutions).

Is there a way to tell plotly to use 100% (or 80%, etc.) of the width (whatever number of pixels that might be).

Answer 1

You can use the use_container_width argument of st.plotly_chart:

st.plotly_chart(fig, use_container_width=True)

st.plotly_chart(fig, use_container_width=True) isn't working for me – Junia

Happy to help, but can you share more context? – Profluent

Adding the setting as recommended had no effect on my figure widths. I'm using plotly figures – Junia

is there any hack to automatically adjust the height ? – Bertrand

Answer 2

fig.update_layout(height=800)

st.plotly_chart(fig,use_container_width=True,height=800)

I used this and it worked fine. I had to use both only then it worked.
