How to add a horizontal line in a bar plot????

Dear all,

i use the command bar for a plot. I want to insert a horizontal line in a bar plot at y = 30. How can I do that? Thank you!

Answer 1

[Azzi Abdelmalek]

xlim=get(gca,'xlim');
hold on
plot(xlim,[30 30])

Isn't the first line unnecessary? xlim is already the x limits - you don't have to call get() to retrieve it, it's already ready to be used "as is". xlim is actually a function itself that returns the x limits.

[Thor]

bar(X);

hold on

plot(xlim,[30 30], 'r')

works too! Thank you all!

A bit shorter:

hline(30,':k','This Line is horizontal')

[Pablo Sánchez]

Does hline() exist? Is yline()
