Just starting to use plotly with Python and trying to figure out how to receive mouse events. So far all the docs I’ve seen seem to imply that the code needs to run on a Jupyter notebook. Is there no way to receive mouse events with Python alone (I am using VSCode if this matters)? I get it that th…

Are you referring to dash? I’m asking because you tagged this topic with Plotly Python

No, I was referring to Plotly with Python. However, if it’s impossible to achieve with Plotly alone and Dash does have this functionality, then I might need to look into Dash as well.

Actually I’m not sure if this is possible in plotly. What do you want to do with the click coordinates? Here an example in Dash: AIMPED/plotly_dash/blob/master/plotlyDash_get_clickInfo.py from dash import Dash, Input, Output, dcc, html from dash.exceptions import PreventUpdate impor…

I am working on optimizing parameters for trading systems. I want to have the following workflow: Optimize with various parameters (I wrote the code in python). Plot the optimization results as a 3D surface (I write the code for this using Plotly Python) A mouse click on any point on the surface s…

This sounds like a Dash app to me. Another option could be using ìpwidgets but I have never used that nor do we have a lot of questions on that on the forums lately. :thinking: [srv_77] Plotly: is there a way to save the data of a clicked point in a list? python, plotly,…

Thanks, I will look into Dash then. I tried to ran examples with ipwidgets but none worked for me on local python, I guess this requires Jupyter or other notebooks which I really don’t want to use.

Hello @Walrus , You should be able to do this through regular python and plotly. It will just take more effort. Id highly recommend using dash as it will be much easier to accomplish.

To follow up on this, I implemented that in Dash but now encounter another problem. My app includes a dcc.Graph with a figure containing a 3D surface plot. A click on the plot is received and processed in a callback with Input(‘opt-graph’,‘clickData’). My issue is that the callback can’t different…
