This is William Huang from the Streamlit Open Source team!
I am currently attempting to provide selection on charts for the Streamlit st.plotly_chart api. I noticed there are on_select and on_click callbacks that we can register to. The on_click callbacks always register and that seems fine.
However, when I try to use the clickmode: “event+select” in the layout of the graph, clicks are sometimes missed. This can be replicated here:
Is there someone that can help me to understand why clicks are being missed? We are trying to release this feature within streamlit so any help would be appreciated!
I created a demo app here: https://chart-selections-demo.streamlit.app/ that uses this clickmode layout property. (FEEL FREE TO CHECK OUT )
