Hi all,

I am wondering if this is possible?

I am plotting using the plot function to make my graph and adding the labels to the points using the text function.

The problem with this is is that I am generating alot of data points and I can't read them individualy easily.

It would be ideal if there is a way to have it so that it plots the points as it's doing now then when I click on the point with the label I want to see this pops up.

Any help is appreciated.

Thanks,

Ollie

You could use the built in datatip functionality.

I'll point you to this answer. This has the behavior I'd want. When I first create the plot, no data tips appear. However, when I turn on the data tip tool, it displays the info I want. This way I can use the build in data tip tool to control when and where the data tip is shown.
