How to draw multiple constant lines?

I want to draw multiple constant lines in a figure. I coded below using xline() and yline() refering Vertical line with constant x-value - MATLAB xline (mathworks.com). But it doesn't work. Would you tell me what is wrong?

xline([1,2,3]);

Could you provide more details about what you mean by 'it didn't work'?

xline([1,2,3]);
xlim([0 5])

Has the ability to include multiple lines changed from Matlab 2020b to 2021a?

I get "Passing multiple values to ConstantLine is not supported." when I try to include multiple x-coordinates to xline.

I'm able to do it in 2021b.

[Cris LaPierre]

Yes. The ability to include a vector of inputs to xline and yline was added in R2021a.

See the corresponding release notes.

When I code like this

clear;
xline([1,2,3]);

error happen.

Error using xline (line 29)
Passing multiple values to ConstantLine is not supported.

Error in test (line 2)
xline([1,2,3]);

I am using R2020b now. Should I install R2021a?

[Cris LaPierre]

It works in R2021a, as you can see. What version of MATLAB are you using?

[Yasuyuki Hamanaka]

I'm using R2020b version: 9.9.0.1592791 Update 5.

I'm going to install R2021a and try it. Thank you.
