horizontal bar plot (from a negative to a positive value in the same line)

Hello,

I am trying to make a horizontal bar plot that will construct a bar for example from -5 to 5.

like the plot in the following picture.

Can anyone help me?

Thank you.

Try this —

figure
patch([-5 5 5 -5], [0.25 0.25 0.75 0.75], 'b', 'FaceAlpha',0.5, 'EdgeColor','none')
axis([-5  5    0  1])
xtix = [-5 -3 -1 1 3 5];
set(gca, 'XTick',xtix, 'XGrid','on', 'XColor','none', 'YColor','none')
text(xtix, zeros(size(xtix)), string(xtix), 'Horiz','center', 'Vert','top')
xline(0, 'Color',[1 1 1]*0.75, 'LineWidth',1.5)

Thank you Star, but I don't think that this is exactly what I am looking for. Imagine that at the end I want to make a plot like this

What can I do?

My pleasure.

‘I don't think that this is exactly what I am looking for’

That is specifically what you asked for!

See the documentation for the barh function.

The SimBiology Toolbox or the Bioinformatics Toolbox may have those sorts of plots as built-in functions. I could not find anything similar to that when I looked, however I did not look closely.
