How to draw a line in a bar chart in complete x area

Is there a way to make the horizontal line start from the very left and go to the very right? It's only going from the first x-marker to the last x-marker.
my code:
cat=categorical({'a','b','c'})
data = [37.6 24.5 14.6]';
errhigh = [2.1 4.4 0.4];
errlow = [4.4 2.4 2.3];
bar(cat,data)
hold on
er = errorbar(cat,data,errlow,errhigh);
er.Color = [0 0 0];
er.LineStyle = 'none';
hold off
line(xlim,[20 20])
output diagramm:

errlow = [4.4 2.4 2.3];
bar(cats,data)
hold on
er = errorbar(cats,data,errlow,errhigh);
er.Color = [0 0 0];
er.LineStyle = 'none';
hold off
% force graphics to update so XLim is accurate
drawnow()
% prevent auto-updating of XLim when new line is made
set(gca(),'XLimMode','manual')
% make the new line
line([0 numel(cats)+1],[20 20])
I changed the variable cat to cats, since cat is the name of an important built-in function.

er.Color = [0 0 0];
er.LineStyle = 'none';
hold off
yline(20) % Use 'yline'
The Run feature is not working for some reason just now, ot it woudl be possible to demonstrate this here.

My pleasure!
You can do something like this —
cat=categorical({'a','b','c'})
data = [37.6 24.5 14.6]';
errhigh = [2.1 4.4 0.4];
errlow = [4.4 2.4 2.3];
bar(cat,data)
hold on
er = errorbar(cat,data,errlow,errhigh);
er.Color = [0 0 0];
er.LineStyle = 'none';
% plot([0 1], [1 1]*20) % Added
plot([0 1; 2 3; 4 5].', ones(3,2).'*20) % All-In-One
hold off
however the placement requires a bit of experimentation, since numeric values of the ‘x’ axis aren’t precisely defined here. (The return from an xlim call is [a c] for example.) If you want them all on the same y-value, you can combine them as in the ‘All-In-One’ plot call, otherwise, it might be easier to use separate plot calls, similar to the commented-out version.
