GRIDXY - Plot grid lines
GRIDXY(X) plots vertical grid lines at the positions specified by X. GRIDXY(X,Y) also plots horizontal grid lines at the positions specified by Y. GRIDXY uses the current axes, if any. Lines outside the plot area are plotted but not shown. When X or Y is empty no vertical or horizontal lines are plotted.
The lines are plotted as a single graphics object. H = GRIDXY(..) returns a graphics handle to that line object.
GRIDXY(..., 'Prop1','Val1','Prop2','Val2', ...) uses the properties and values specified for color, linestyle, etc. Execute GET(H), where H is a line handle, to see a list of line object properties and their current values. Execute SET(H) to see a list of line object properties and legal property values.
% some random plot
plot(10*rand(100,1), 10*rand(100,1),'bo') ;
% horizontal red dashed grid
gridxy([1.1 3.2 4.5],'Color','r','Linestyle',':') ;
% vertical solid thicker yellowish grid, and store the handle
h = gridxy(,[2.1:0.7:5 8],'Color',[0.9 1.0 0.2],'linewidth',3) ;
GRIDXY can be used to plot a irregular grid on the axes.

Nice! A good workaround to overcome a little limitation of Matlab in plots edition.
gridxy(get(gca,'xtick'),get(gca,'ytick'),'color',[.4 .4 .4],'linewidth',1,'linestyle',':')
It's just what I'm looking for! Many thanks!
Works on R2014a as well.
works for me (R2011b)
Good suggestion from Carey Smith:
Is anyone else having trouble running this on Release 2014B? I have just upgraded to that version and I now find that the uistack function (i.e. where this function puts the new grid-lines at the bottom) takes a very long time to run (I did have a large number of objects but this problem didn't happen on my previous Matlab version).
Thank you very much for the sharing. This is also the one that I am looking for.
Exactly the one I was looking for
Let me just chime in with all the others...
Great routine! This should be included in Matlab.
Fantastic--just what I needed!
Worked for me thanks.
% I had to comment-out uistack(h,'bottom') for an imagesc plot
% (Otherwise, the grid lines are not visible.)
% These examples worked for me & simplified some aspects of using this function:
@Chiara. You can use, e.g.,
h(1) = gridxy(MedianValue ,'color','r')
h(2) = gridxy(MeanValue ,'color','b')
Very useful - but i'd need to add a legend with entries for the vertical bars. EG i have a histogram, and two vertical bars, say one for the mean and one for the median. How can i do this?
@Phil, in 3D the lines would become planes. Is this what you want? You can also take a look at REFLINEXYZ to see if that better fills your needs:
this code is exactly what I need. Unfortunately I need it in three dimensions. Does any body have an idea?
Otherwise I will try to extend this m-file but I have a feeling that this will take me lots of time
Great Program. It'd be even better if it can accept an axes handle as its first input. For the moment, since I need it in a hurry, I tapped into your code and changed this:
function hh = gridxy(hca, x,varargin)
Very nicely done. This is what should have been in matlab. Thanks for you efforts!!
Perfect, exactly what I needed !
This is what I need!! Works very well!! Thanks a lot!!
Just what I needed, cheers
The 'undesired behavior' mentioned by Jim Gerrling has been fixed in v2.2
You can fix the axis issue by
Unfortunaltely, the script plots over the Ticks and the axis (let's say you use green gridlines, they print over the ticks and axis).
very good, thanks
Just what I needed, again a very useful script, thanks
Thank you for a very useful utility. It works well in all of my applications so far.
Name change. Add an error check for line properties
