Somehow making an animation with 'addpoints' enables a control slider for the user to slide back and forth to view the animation, but sometimes the slider disappears. Which syntax ensures that it appear?

I'm not aware of a slider that automatically appears after running the code you shared.

If this is run in an app or live script, a uislider could be added, though.

Yes, in a live script! My newest concern is how to stop an animation loop perhaps through a uicontrol in a live script?

The slider you are referring to is called a "data cursor" in MATLAB. By default, it appears when you create a plot with a line object, and you hover over the line with your mouse cursor. However, it may not always appear when using “addpoints” to animate a plot.

To ensure that the data cursor appears, you can use the “datacursormode” function in MATLAB. This function allows you to enable or disable the data cursor mode for a specific plot or all plots in a figure.

You can also customize the appearance and behavior of the data cursor using various options available in the “datacursormode” function.

thanks a lot. "it may not always appear when using “addpoints” to animate a plot." Does the appearance depends on luck? How can this be a random event?
