Numeric text edit field filled out automatically when I clicked in the plot's either X_axis or Y_Axis. Is that possible in matlab app designer?

For example: Here, we have plot vehicle count vs time. I want to use plot's some values in my app for further process. Like if I click on 15s on time_axis, it take value from plot and fill that value in text edit field of the app. So, I don't have to put value manually in edit field. Is that possible in matlab? if yes, could you share links, where I can get idea about it.

Hi,

Yes, you can use MATLAB's interactive features to capture user input from a plot and update a text edit field in your app accordingly

1. Create your MATLAB app using the App Designer.
2. Add a plot to your app's UI where the vehicle count vs. time data is displayed.
3. Add a callback function to the plot's ButtonDownFcn property. This function will be triggered when the user clicks on the plot.
4. In the callback function, capture the x-coordinate (time) of the clicked point using the CurrentPoint property of the plot.
5. Retrieve the corresponding value from the plot data based on the clicked x-coordinate (time).
6. Update the text edit field in your app with the retrieved value.

Hope it helps!
