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(..., 'Prop1','Val1','Prop2','Val2', ...) uses the properties and values specified for color, linestyle, etc.
plot(10*rand(100,1), 10*rand(100,1),'bo') ; % random points
gridxy([1.1 3.2 4.5],'Color','r','Linestyle',':') ; % horizontal red dashed grid
h = gridxy(,[2.1:0.7:5 8],'Color',[0.9 1.0 0.2],'linewidth',3) ; % vertical solid thicker yellowish grid, and store the handle
GRIDXY can be used to plot a irregular grid on the axes.

@Rodolfo: ax = gca ; gridxy(ax.XAxis.MinorTickValues,) ...
How do I use this function to allow plotting minor grids as well? I used GRIDXY in a simple loglog plot, but it only displayed the major lines. For example:
x = logspace(-1,2);
y = exp(x);
gridxy(get(gca,'xtick'),get(gca,'ytick'),'color',[0.5 0.5 0.5],'linewidth',1,'linestyle',':')
thanks very much it's so helpful your function
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.
