GRIDXY (v2.2 feb 2008)

plot horizontal and vertical grid

Description

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.
 
Examples
% 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.

Very useful!

[Alan Eskovitz]

Thank you for a very useful utility. It works well in all of my applications so far.

[David Ward]

Just what I needed, again a very useful script, thanks

[Abderrezak Bouchedda]

very good, thanks

[Jim Gerrling]

Unfortunaltely, the script plots over the Ticks and the axis (let's say you use green gridlines, they print over the ticks and axis).

[Jim Gerrling]

You can fix the axis issue by
set(gca,'Layer','top')

[Jos (the author)]

The 'undesired behavior' mentioned by Jim Gerrling has been fixed in v2.2

[Fred De Masi]

Just what I needed, cheers

[Rhymer Yang]

This is what I need!! Works very well!! Thanks a lot!!

[Mo Al Lawati]

Perfect, exactly what I needed !

[Laxman P]

Very nicely done. This is what should have been in matlab. Thanks for you efforts!!

[Hoi Wong]

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)

if(isempty(hca))
hca=get(get(0,'currentfigure'),'currentaxes')
end

[Phil]

Hello everyone,

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

thanks

Philipp

@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:

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?

[Jos]

@Chiara. You can use, e.g.,
 h(1) = gridxy(MedianValue ,'color','r')
 h(2) = gridxy(MeanValue ,'color','b')
legend(h,{'Median','Mean'})
