In Matlab figure, I would like to remove ticks only from the top and right axes with keeping the plot box on.
I know if I make the plot box off, the ticks on the top and right go away. But, this is not what I want. In other words, I want to keep ticks only at the bottom and left and, at the same time, want to keep the plot box on.
My workaround similar to #j_kubik proposition:
plot(1:10)
% get handle to current axes
a = gca;
% set box property to off and remove background color
set(a,'box','off','color','none')
% create new, empty axes with box but without ticks
b = axes('Position',get(a,'Position'),'box','on','xtick',[],'ytick',[]);
% set original axes as active
axes(a)
% link axes in case of zooming
linkaxes([a b])
You can use box off to remove the ticks and then draw the box back using plot. For example:
figure
hold on
box off
plot(1:10)
plot([1,10],[10, 10],'k')
plot([10,10],[1,10],'k')
Now in 2022, if anyone is still interested in a quick resolution other than the box option, here is my answer:
figure
plot(1:10) ;
ax = gca ;
ax.Box = 'off' ;
xline(ax.XLim(2),'-k', 'linewidth',ax.LineWidth);
yline(ax.YLim(1),'-k', 'linewidth',ax.LineWidth);

I would like to place an arrow over a legend in a matlab plot but when I add the arrow, the legend defaults to being "on top" (see the picture, the black line being covered by the legend).
Is there a way to push a subfigure, such as an arrow, to the "top" so that it appears over all other component of the figure, including the legend? I've tried to use uistack but that doesn't seem to work with legends. uistack as the doc says should "Reorder visual stacking of UI components".
edit:
Very simple example: the line that I'm drawing should appear on top of the legend.
figure;
b = bar(1:3,rand(3));
hold on;
p = plot([0,3],[0,.5],'Color','k','linewidth',1.5); % my arrow
l = legend(b,'value','Location','SouthWest','AutoUpdate','off');
uistack(l,'bottom');
You can make the legend background transparent - so you will see your arrow through the legend
figure;
b = bar(1:3,rand(3));
hold on;
p = plot([0,3],[0,.5],'Color','k','linewidth',1.5); % my arrow
l = legend(b,'value','Location','SouthWest','AutoUpdate','off');
l.BoxFace.ColorData = uint8([255 255 255 127]');
l.BoxFace.ColorType = 'truecoloralpha';
The ColorData Property is [R G B Transparency]
For Info: This was done using R2015b.
You can copyobj the current graphical axes gca and set its Color property to none. This method will draw the line over the legend's patches and associated texts.
Explanation : Copyobj will copy and display all the axes related to the bar and line but not the legend (legends have axes on their own). The display of the copied axes will overlay perfectly with the original one. And 'Color','none' makes the white background of the copied axes transparent, thus making the legend visible again but visible under the line.
Here is the code
f = figure;
b = bar(1:3,rand(3));
hold on;
p = plot([0,3],[0,.5],'Color','k','linewidth',1.5); % my arrow
l = legend(b, 'Location','SouthWest');
% add some magic
hax = copyobj(gca, f); % copy the current axes to the figure
set(hax, 'Color', 'none') % set the new axes's background transparent
What MATLAB version do you use? uistack seems to not work on legends anymore, since MATLAB 2015b (see this similar problem).
If, as you say, the line can be appear at any place, the best workaround may be choosing the best legend location
l = legend(b,'value','Location','Best','AutoUpdate','off');
I use some things from this question get-rid-of-the-white-space-around-matlab-figures-pdf-output to get rid of the white space when saving figure plots and images. This works fine, but my problem is when I use commands like "axis square" or "axis image". Ivt sets TightInset property of corresponding axes to 0 in "y" direction. I mean when I use this:
inset=get(a,'TightInset');
second and fourth numbers in "inset" are always zero, even if I set title and x-label. So in the end I don't see plot titles and x-labels.
Can I fix it somehow? So far I do it manually by adding some suitable number, but it is not convenient.
EDIT: Some more code for example. It displays two histograms.
h=figure;
subplot(121)
bar(bins,histogram1,'hist');
axis square
title('Historgram 1');
xlabel('Intensity');
ylabel('Pixel count');
set(gca,'xlim',[0 1])
subplot(122)
bar(bins,histogram_out,'hist');
axis square
title('Histogram 2');
set(gca,'xlim',[0 1])
xlabel('Intensity');
ylabel('Pixel count');
and if I call
a=get(h,'Children');
for i=1:length(a)
inset=get(a(i),'TightInset');
%...some stuff here
end
those y-related numbers in inset are zeros. If I comment axis square and do this, then inset are correct and it does what I need.
As far as I know when you use 'TightInset' you'll get only the graph or image, axis will be removed. I downloaded a function from mathworks file exchange 'saveTightfigure.m' to solve a similar problem. But I did not needed axes. If you need axes may be you can edit limits set inside the function. I mean you can give a little more space at left and bottom for keeping the axes.
Provided with some code like the following:
x=1:.5:10
plot(x,sin(x))
set(gca,'box','on')
I'm trying to get the left axis to maintain it's tick marks and the right axis to have none.
I know I don't want to do the following:
set(gca,'box','off')
set(gca,'Ytick','[]') %this turns off the left and right axes tick marks. I just want the right off.
I would really,really prefer to not use plotyy. Any help would be appreciated.
Are creating dumby axes the only option here?
http://www.mathworks.com/matlabcentral/newsreader/view_thread/261486
I think that you are stuck using a dummy axes (or a variety of even more unappealing options).
FWIW, the code required is only a few lines; the shortest I can get it is below:
a1 = axes('box','on','xtick',[],'ytick',[]); %Under axis, used as background color and box;
a2 = axes(); %Over axis, used for ticks, labels, and to hold data
propLink = linkprop([a1 a2],'position'); %Keep the positions the same
x=1:.5:10 %Make and plot data
plot(a2, x,sin(x))
set(a2,'box','off','color','none'); %Set top axes props last ("plot" overrides some properties)
I have a simple plot in Matlab but as you can see from the screenshot. There is a lot of white space on the right side of the graph after the end of the data series.
Any idea how to get rid of this white space and make the plot go right to the edge of the figure? Here is my code:
Plotx = plot(x);
hold on
PlotState = plot(Y);
set(Plotx,'Color','black','LineWidth',2.5);
set(PlotState,'Color','red','LineWidth',2.5);
set(gca, 'XTick',(1:3:62))
labels = time;
set(gca,'XTickLabel',labels(1:3:62))
grid on
This usually works for me:
axis tight;
xlim('auto');
You must select your figure, go back to the console and use those commands so they affect the last active figure.
EDIT: The above line should automatically make your graph axis very tight on your data. For more fine control, you may want to define the axis limits manually:
axis([xmin,xmax,ymin,ymax])
I found a solution. I manually adjust the limit of the x-axis, using:
set(gca,'XLim',[0 63])
Matlab is displaying a black border around a plot and I would like to remove it. I think i should be using something like:
set(Figure#,'PropertyName',PropertyValue);
But I'm not sure what PropertyName or PropertyValue should be used...
Edit:
I tried all of the suggestions including:
set(gca,'box','off');
set(gca,'xcolor','w','ycolor','w','xtick',[],'ytick',[]);
axis off;
The figure still has a black boarder and looks like this:
Edit 2:
This is a simplified package that reproduces the black box. Run the script called "runPlot". Here it is:
http://dl.dropbox.com/u/8058705/plotTest.zip
I can't figure out why the box is still visible. This might be due to the line in "plotTEC.m"
axis([-.65 .6 .25 1.32]) % hardwiring axis length since the coastline runs off of the plot
#Pursuit: If I use "plot browser" I get a recursive error....I am not familiar with the matlab plotting package but this seems strange. Does anyone else get this error? Again, thank you guys for your advise!
Does anyone have any other suggestions?
Thanks in advance!
You want to experiment with the properties of the axis. Some properties of interest.
xcolor %The color of the x-axis line and the x axis labels
ycolor %
box %'on', or 'off' indicating if one or both sides of a plot should have lines
xtick %Where to place the labels
ytick
For a completely bare plot, use:
figure
set(gca,'xcolor','w','ycolor','w','xtick',[],'ytick',[])
To set the figure background to white as well
set(gcf,'color','w')
Depending on your exact problem, you can try the 'box' property, to see how it affects your plots
set(gca,'box','on')
set(gca,'box','off')
If you want to turn off the actual plots lines but keep the plot labels then I am not aware of a simple solution. I think that I would need to remove the axes as described above, and then manually add labels using the text function.
Edit: As I just learned from this question, Plot Overlay MATLAB you can also try
axis off
axis on
Which I think is equivalent to
set(gca,'visible','off')
set(gca,'visible','on')
Edit 2:
If nothing else works, activate the "plot browser" in your figure. Use "view" --> "plot browser". From the plot browser panel, uncheck each object until you figure out which object is drawing the lines that you need to remove.
Then double click on the offending object to bring up the "property editor" panel, and mostly likely click "More properties" to view all possible properties of that object. From that view you can (hopefully) figure out what object is drawing the offending lines.
After you have figured out the object and property to edit, you can probably figure out where in the code that object is created, and set the property programmatically.
Try:
set(gca, 'Box', 'off');
Solution to remove 'gray' background in imagesc
I = imread('imgname.jpg');
[rows columns] = size(I);
posX = 100; posY = 100; %you can set any value for posX and posY - try to keep it on screen
f = figure (1);
imagesc(I);
set(gcf,'Position',[posX posY columns rows]);
set(gca,'units','pixels');
set(gca,'units','normalized','position',[0 0 1 1]);
axis off;
axis tight;
This should save the image with same size as that of the original, using imagesc.
Cheers!
set( gca , 'Visible' , 'off' );
