As per https://justpy.io/#if-you-have-questions-suggestions-or-would-like-to-get-in-touch i have converted this to a discussion item.
If you have a question about JustPy you are welcome to check stackoverflow questions tagged justpy and Especially questions which involve details of upstream frameworks such as ag-grid, highcharts, pandas, plotly, quasar, tailwind and others are best ask involving the larger stackoverflow community and tagging your question with both "justpy" and the tag of the specific library your are asking a question for such as "ag-grid", "highcharts","quasar", "pandas" and others.

Unforunately your question is very unspecific. You are right that neither "zoom" nor "chart map" nor "mousewheel" give any hit in the search of https://justpy.io/ even a stackoverflow search https://stackoverflow.com/search?q=zoom+chart+map+mousewheel does not give any results.

Still i will try to guess what you are trying to find out.
"chartmap" seems to refer to "highmap".

Searching the web for zoom highmap there are quite a few answers. One is specifically about zoom by mouse scroll:
https://stackoverflow.com/questions/36490209/highmaps-how-to-disable-map-zoom-by-mouse-scroll

You might want to get yourself a stackoverflow account and upvote the question (5) and answer (11).

Now the specific setting https://api.highcharts.com/highmaps/mapNavigation.enableMouseWheelZoom mentioned there is something that is worthwile discussing in the context of justpy. Justpy only transports settings by "remote DOM rewriting". It's a valid question how to do this - please repeat this detailed question with some code example as per the stackoverflow Q&A guidelines on stackoverflow and i'll happily answer you there.

http://jsfiddle.net/Frank_Lou/wdu9axoL/23/ has an example fiddle where you can try things out with javascript before trying the python remote rewriting.
