I want to add a grid on my plot. Unofrtunetely, I found only Grid normal and Grid miror,
I want to add a grid that appear every 5 value on y-axis, This is my code:
function DisplayNumber(x,y1,y2,Name,Method)
plot(x,y1,'-s','MarkerSize',9,...
'MarkerEdgeColor','green',...
'MarkerFaceColor',[0 0.4470 0.7410])
hold on
legend({'cos(x)','cos(2x)','cos(3x)','cos(4x)'},...
'Location','northwest','NumColumns',2)
p=plot(x,y2,'-s','MarkerSize',9,...
'MarkerEdgeColor','yellow',...
'MarkerFaceColor',[0.6350 0.0780 0.1840])
hold off
xtickangle(0)
max(y1);
Max= max( max(y1),max(y2));
ylim([0 Max+10]);
Max=max(x);
xlim([1 Max+1]);
legend( strcat(Method,"-AHP"),strcat(Method,"-MOWOA-NIS"));
ylabel('Rank reversal ratio %');
xlabel('Number of networks');
xticks(0 : 20)
grid on
set(gcf,'Units','Inches');
pos = get(gcf,'Position');
set(gcf,'PaperPositionMode','Auto','PaperUnits','Inches','PaperSize',[pos(3), pos(4)])
print(gcf,Name,'-dpdf','-r0')
end
I tried yticks(0:5:Max+10) but it did not work.

I have a three-dimensional density distribution and create a figure with two subplots. One of the XY plane and one of the YZ plane. For both figures I want a correct colorbar and for some reason the XY plane colorbar is perfect and the YZ plane colorbar is too big and overlaps the figure title. See below for my code and an image of result. EDIT: added functioning example at bottom
%// Data slice in the XY plane
subplot(1,2,1)
h=slice(xi,yi,zi,density,[],[],0);
set(h,'edgecolor','none');
caxis([-8,-2])
colormap(jet);
c = colorbar;
c.Label.String = 'Density in log 10 scale';
view(2)
daspect([1 1 1])
xlabel('X-axis [km]')
ylabel('Y-axis [km]')
zlabel('Z-axis [km]')
title_orbit = ['Mg sputtering in orbital plane at orbit angle ',is];
title({title_orbit,''})
%// Data slice in the YZ plane
subplot(1,2,2)
g=slice(xi,yi,zi,density,0,[],[]);
set(g,'edgecolor','none');
caxis([-8,-2])
colormap(jet);
d = colorbar;
d.Label.String = 'Density in log 10 scale';
view(90,0)
daspect([1 1 1])
xlabel('X-axis [km]')
ylabel('Y-axis [km]')
zlabel('Z-axis [km]')
title_perp = ['Mg sputtering in perpendicular plane at orbit angle ',is];
title({title_perp,''})
For those who want a working example for trying to fix it, see code below.
% Create data with similar structure as original
x = linspace(-100,100,100);
y = linspace(-100,100,100);
z = linspace(-100,100,100);
[xg,yg,zg] = meshgrid(x,y,z);
density = rand([100,100,100]);
% Plot data
figure
subplot(1,2,1)
h=slice(xg,yg,zg,density,[],[],0);
set(h,'edgecolor','none');
colormap(jet);
c = colorbar;
view(2)
daspect([1 1 1])
subplot(1,2,2)
g=slice(xg,yg,zg,density,0,[],[]);
set(g,'edgecolor','none');
colormap(jet);
c = colorbar;
view(90,0)
daspect([1 1 1])
here's a possible workaround, first get the color data from each slice, then use imagesc or imshowto plot that slice data. Using your example:
h=slice(xg,yg,zg,density,0,[],[]);
H=get(h,'CData');
...
g=slice(xg,yg,zg,density,0,[],[]);
G=get(g,'CData');
...
Then open a new figure and use imagesc or imshow:
figure;
subplot(1,2,1)
imshow(H); colormap(jet); colorbar
subplot(1,2,2)
imshow(G); colormap(jet); colorbar
I am plotting two maps next to each other using subplot. However, now, the image is turning out like this:
Is there any way to make the map part of the image larger? I would like to plot the maps side by side, by in this image, the resolution is low and the size is small.

To change the amount of space the data occupies in the figure, you can use this command:
set(gca,'Position',[0.1 .1 0.75 0.85])
You'll have to play with the numbers a bit, to get things look nice. Note that Matlab rescales everything when you resize the figure window, so the optimal numbers depend on the window size you want to use.
On the other hand, you want to make the map bigger in comparison to the colorbar. You cannot make it without changing your window size, because your maps are already as high as the color bars. I would suggest to:
Set caxis to the same range in both plots.
Remove the colorbar on the left one.
Increase the height of your figure window to make the maps occupy as much width as possible.
Put the two images nicelye side by side using the command above.
For more information, see Matlab Documentation on Axes Properties.
Example:
% Default dimenstions
figure
x = 1:.1:4;
y = x;
[X, Y] = meshgrid(x,y);
subplot(1,2,1)
h = pcolor(X, Y, sin(X).*cos(Y)*2);
set(h, 'EdgeAlpha', 0);
axis square
colorbar
subplot(1,2,2)
h = pcolor(X, Y, sin(Y).*cos(X));
set(h, 'EdgeAlpha', 0);
axis square
colorbar
% adjust dimensions
subplot(1,2,1)
set(gca, 'Position', [0.1 0.1 0.3 0.85])
subplot(1,2,2)
set(gca, 'Position', [0.55 0.1 0.3 0.85])
This blog post has many great examples of FileExchange scripts dealing with size of subplots.
subplot_tight works very well and makes the subplots larger. Instead of writing in subplot(1,2,1), use subplot_tight(1,2,1)
My problem was similar -> scaling subplots in a figure a bit more up. Important for me though, was to maintain the aspect ratio that I've set before.
Enhancing the answer from #texnic in order to not have to set the values manually, one might use the following:
scale = 1.1; % Subplot scale
subplot(1,2,1)
% Your plotting here ...
pos = get(gca, 'Position'); % Get positions of the subplot [left bottom width height]
set(gca, 'Position', [pos(1) pos(2) pos(3)*scale pos(4)*scale]); % Scale width and height
Understanding this, one can also easily implement a parametric move of the subplot.
I am trying to plot 3 curves using the semilogx matlab function and add a fourth line to an additional y axis on the right. All of them should be plotted on the same logarithmic scale for the x-axis. The following code indicates the derived error; the x-axis is incorrect. The figure has to have a single x-axis mode of ticks, the logarithm one. How could this be fixed?
Plus, how can I add a legend for these 4 curves?
close all, clc
figure, semilogx([1:100:1000],[rand(1,10)],'bo-'),
xlabel('xlabel'),ylabel('ylabel'), hold on;
semilogx([1:100:1000], [rand(1,10)], 'ro-'), hold on,
semilogx([1:100:1000], [rand(1,10)], 'ko-'), hold off
legend('1','2','3','Location','Best')
ax1 = gca;
ax2 = axes('YAxisLocation','right',...
'Color' , 'none',...
'YColor', 'm');
linkaxes([ax1 ax2 ], 'x')
x4 = [1:100:1000];
y4 = [rand(1,10)*2];
line(x4, y4, 'color', 'm', 'Marker','x','LineStyle',':', 'parent',ax1)
ylabel('y2')
You can use plotyy function to plot two of your lines, one on the right and one on the left. You can then hold on and plot the remaining lines using semilogx.
plotyy([1:100:1000], [rand(1,10)], [1:100:1000], [rand(1,10)]*2, #semilogx);
hold on;
semilogx([1:100:1000], [rand(1,10)], 'ro-');
semilogx([1:100:1000], [rand(1,10)], 'mo-');
hold off;
legend('Line1','Line2','Line3','Line4','Location','Northwest')
I need to plot a x-y function, that shows the histograms at x-values. Something similar to the bottom plot of the next figure:
I tried to use matlab's "barh", but can't plot many in the same figure.
Any ideas?
Or, maybe displacing the origin (baseline, basevalue in barseries properties) of successive plots would work. How could I do that for barh?
thanks.
Using 'Position' of axes property
% generate "data"
m = rand( 40,10 );
[n x] = hist( m, 50 );
% the actual plotting
figure;
ma = axes('Position',[.1 .1 .8 .8] ); % "parent" axes
N = size(n,2); % number of vertical bars
for ii=1:N,
% create an axes inside the parent axes for the ii-the barh
sa = axes('Position', [0.1+(ii-1)*.8/N, 0.1, .8/N, .8]); % position the ii-th barh
barh( x, n(:,ii), 'Parent', sa);
axis off;
end
How to plot something outside the axis with MATLAB? I had like to plot something similar to this figure;
Thank you.
Here is one possible trick by using two axes:
%# plot data as usual
x = randn(1000,1);
[count bin] = hist(x,50);
figure, bar(bin,count,'hist')
hAx1 = gca;
%# create a second axis as copy of first (without its content),
%# reduce its size, and set limits accordingly
hAx2 = copyobj(hAx1,gcf);
set(hAx2, 'Position',get(hAx1,'Position').*[1 1 1 0.9], ...
'XLimMode','manual', 'YLimMode','manual', ...
'YLim',get(hAx1,'YLim').*[1 0.9])
delete(get(hAx2,'Children'))
%# hide first axis, and adjust Z-order
axis(hAx1,'off')
uistack(hAx1,'top')
%# add title and labels
title(hAx2,'Title')
xlabel(hAx2, 'Frequency'), ylabel(hAx2, 'Mag')
and here is the plot before and after:
You can display one axis with the scale you want, then plot your data on another axis which is invisible and large enough to hold the data you need:
f = figure;
% some fake data
x = 0:20;
y = 23-x;
a_max = 20;
b_max = 23;
a_height = .7;
%% axes you'll see
a = axes('Position', [.1 .1 .8 a_height]);
xlim([0 20]);
ylim([0 20]);
%% axes you'll use
scale = b_max/a_max;
a2 = axes('Position', [.1 .1 .8 scale*a_height]);
p = plot(x, y);
xlim([0 20]);
ylim([0 b_max]);
set(a2, 'Color', 'none', 'Visible', 'off');
I had similar problem and I've solved it thanks to this answer. In case of bar series the code is as follows:
[a,b] = hist(randn(1000,1)); % generate random data and histogram
h = bar(b,a); % plot bar series
ylim([0 70]) % set limits
set(get(h,'children'),'clipping','off')% turn off clippings
