Is there a function that shows the value of the points on a plot as your mouse runs over them?

Hi,

I was wondering if anyone knew of a function, possibly in File Exchange, that would display the x and y coordinates of a plot as you hover your mouse over it. Or maybe there are crosshairs that follow along the line of a plot while displaying the values of the coordinates?

Thank you for the help

I found this function https://www.mathworks.com/matlabcentral/fileexchange/1038-plot-crosshairs to plot crosshairs on the graph but if anyone has any other advice or any other ideas, please let me know

I'm not aware of any builtin functionality, I've always programmed my own behaviour in that line. I tend to forget to look in File Exchange, but I usually prefer my own code anyway.

What about the build-in "Data Cursor"? Make a plot, go to "Tools", turn on "Data Cursor". Or, click the "Data Cursor" icon on the Figure Toolbar.

You will need to click the data point, instead of hover over it.

Did not know about this. This is great, thank you!
