'addpoints' animation with a control slider

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?

Could you attach a minimal working example that reproduces the problem?

Also please fill in your release information in the right side panel of this thread.

[feynman feynman]

h =animatedline(Color=[0.85 0.325 0.098]);
for x = linspace(0,4*pi,10000)
    y = sin(x);
    addpoints(h,x,y)
    drawnow
end

I wanted to add the release info in the right panel but wasn't able to do so.

release info=r2021a

You have to specify a product before you can specify a release.

Are you using a regular figure produced by figure or a uifigure or is this within an app?

Are you using a uislider?

[feynman feynman]

thank you, just a regular figure

[feynman feynman]

as long as sth that can help control the animation, replay and stop

[Adam Danz]

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.

[feynman feynman]

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?
