Expected behavior:

One can see histogram plot in streamlit need to press play button to run where as the same plot in webbrowser is running automatically. Is it possible for streamlit-plotly graph run automatically like auto_play=True.
B. Also the yaxis in top graph saying sum of value instead of conc

Hey @hrani,

Is this same histogram autoplaying when it’s not in a Streamlit app?

Yes, from the last 3 line if one can run, browser opens and graph runs

st.plotly_chart(fig_bar,auto_play=True) won’t autoplay it since that’s not a supported parameter. One thing I would try is using offline mode (sharing=streamlit) and then passing Plotly’s autoplay parameter to **kwargs.
