Selecting Heatmap Data

Dear all,

I have a question that is relatively easy, yet not adressed anywhere I could find it. I am making a heatmap in Dash with the possibility to select certain area’s of the heatmap (to process further in other plots). Is there any way to realize this? Should I be using a heatmap or another plot? I am visualizing Adjacency Matrix data. Any help is welcome :slight_smile:

This is a dummy plot of the data I’m visualizing:

Thanks for writing in! Unfortunately lasso or box select isn’t available for heatmaps at the moment, this is a limitation of plotly.js, but one we have an open issue addressing: https://github.com/plotly/plotly.js/issues/170
