When drawing a ConstantLine with xline or yline, it doesn't show up in the plotbrowser.
Ex :
xline(5, 'DisplayName', 'test'); plotbrowser;
How to solve this ?

I'm having, what may be, similar issues.
I have tried to use findobj('type', 'constantline') and given the "xlines" a tag (findobj('tag', 'xlinetag') but this results in a 0x0 graphicsobj.
Using R2022B

@Peter
If you happen to be drawing into a uiaxes then the handlevisibility of the axes might be set to off so findobj() might not notice the handle. Try findall('tag', 'xlinetag')

Hi Pierre,
By default, ConstantLines drawn with xline or yline may not show up in the Plot Browser when using MATLAB R2019b or earlier versions. This is a known issue with these versions of MATLAB, but it has been fixed in MATLAB R2020a and later versions.
To work around the issue in MATLAB R2019b or earlier versions, you can manually add a legend entry for the ConstantLine using the legend function. Here's an example:
Hope it helps.
x = 1:10;
y = x.^2;
figure;
plot(x, y);
hold on;
h = xline(5, 'DisplayName', 'test');
legend(h, 'Location', 'south');

Hello Shaik, I am using R2020b and this solution does not work neither.
I am not speaking about the legend, but about the plot browser that I extensively use to select/deselected named lines. Here is the result with your solution.
I am waiting for the ConstantLine to appear in the right panel with name 'test'.
