I have question regarding width and height of Plots. If we have multiple plots in same figure how can we set the size for each plot on our own.
Also is there a way to have multiple plots without using subplots?
Start with subplots (calling subplot returns you an axes handle). Then set the Position property on each subplot axes handle.
Create all the subplots before you start moving them, because creating a subplot afterwards will automatically remove any existing subplot that overlaps the default location of the new one.

I'm trying to plot several data on subplots, but each one have its own range of color (colorbar) and I want all to be the same. I can change the labels of the colorbar but if ranges are too different it would mostly show only one color. Is there a way to make matlab think that its all just one plot and then decide the colorbar scale accordingly?
To change colorbar label its quite easy:
allaxes = findall(f, 'type', 'axes');%f is the figure handle
for i=1:length(allaxes)
cc=get(allaxes(i),'Colorbar');
mm(i,:)=get(cc,'Limits');
end
limits=[min(min(mm)) max(max(mm))];
for i=1:length(allaxes)
cc=get(allaxes(i),'Colorbar');
set(cc,'Limits',limits);
end
Here there is an example (look for the one on the right):
I tried using axes for displaying images in Gui.But, before displaying any images, the axes is shown with a plot figure while running the GUI, something like below.
You can see the default axes being displayed. Is there a way to display the axes in running GUI without displaying these plot figures? So that when the image is not displayed in the axes, nothing is displayed. Thanks in advance.
UPDATE 1
I have used 9 axes here, thus the long trail of y axis.
Yes, you can use
axis off
To remove the axes from the empty plots. Then use
axis on
When you actually plot something to bring them back.
Best,
Hi I'm trying to implement as following code.
plot(bins,r);
plot(bins,g);
plot(bins,b);
But I want to plot in one figure.
Is there any way?
For multiple plots in the same figure and not the same axis. You have to use subplot(x,y,z). The first argument 'x' is the number of plot you want to produce, in your case 3. Second 'y' just adjusts the size of the plots, you can use 1. The third 'z' is the position of the plot, whether a certain plot comes first, second or third.
subplot(3,1,1)
plot(bins,r);
subplot(3,1,2)
plot(bins,g);
subplot(3,1,3)
plot(bins,g);
To distinguish between all three plot you can add another argument to plot() so that you can change colors. For example:
plot(bins,r,'r')
'r' will make the color of the plot red, 'b' makes it blue, 'k' makes it black...so on.
Yes, you can plot everything in one go:
plot(bins,r,bins,g,bins,b)
or use hold on after the first call to plot.
You need to use hold on
hold on retains plots in the current axes so that new plots added to
the axes do not delete existing plots. New plots use the next colors
and line styles based on the ColorOrder and LineStyleOrder properties
of the axes. MATLAB® adjusts axes limits, tick marks, and tick labels
to display the full range of data.
hold on
plot(bins,r)
plot(bins,g)
plot(bins,b)
I'm creating a simple GUI in MATLAB and I'm trying to create a figure that contains a 2d plot on an axes, all is working well, but I have a rough time trying to figure out how to fix the position of the axes/plot.
The axes seems to scale with the figure window size. If I maximize the figure on my screen, the axes is maximized within, etc. What I want to accomplish is to have a row of buttons beneath the plot on the same figure as the plot, basically an area of 50 (ish) pixels tall that the plot does not encroach on. I know how to do this in HTML, but I can't figure out a good way in MATLAB.
Any alternative approaches would also be greatly appreciated.
Change the units of the axes to anything other than 'normalized', like 'pixels'. Then it won't automatically resize with the figure. From this documentation page:
When you create a graph, MATLAB® creates an axes to display the graph. The axes is sized to fit in the figure and automatically resizes as you resize the figure. MATLAB applies the automatic resize behavior only when the axes Units property is set to normalized (the default).
Use set(gca,'Position',pos) where pos = [x y w h] to set the position and size of the axes in the units you chose.
See this answer for an example and a function for holding an axis size once you have it in place.
I have multiple subplots in one figure. The X axis of each plot is the same variable (time). The Y axis on each plot is different (both in what it represents and the magnitude of the data).
I would like a way to zoom in on the time scale on all plots simultaneously. Ideally by using the rectangle zoom tool on one of the plots, and having the other plots change their X limits accordingly. The Y limits should remained unchanged for all of this. Auto fitting the data to fill the plot in the Y direction is acceptable.
(This question is almost identical to Stack Overflow question one Matplotlib/Pyplot: How to zoom subplots together? (except for MATLAB))
Use the built-in linkaxes function as follows:
linkaxes([hAxes1,hAxes2,hAxes3], 'x');
For more advanced linking (not just the x or y axes), use the built-in linkprop function
Use linkaxes as Yair and Amro already suggested. Following is a quick example for your case
ha(1) = subplot(2,1,1); % get the axes handle when you create the subplot
plot([1:10]); % Plot random stuff here as an example
ha(2) = subplot(2,1,2); % get the axes handle when you create the subplot
plot([1:10]+10); % Plot random stuff here as an example
linkaxes(ha, 'x'); % Link all axes in x
You should be able to zoom in all the subplots simultaneously
If there are many subplots, and collecting their axes handle one by one does not seem a clever way to do the job, you can find all the axes handle in the given figure handle by the following commands
figure_handle = figure;
subplot(2,1,1);
plot([1:10]);
subplot(2,1,2);
plot([1:10]+10);
% find all axes handle of type 'axes' and empty tag
all_ha = findobj( figure_handle, 'type', 'axes', 'tag', '' );
linkaxes( all_ha, 'x' );
The first line finds all the objects under figure_handle of type "axes" and empty tag (''). The condition of the empty tag is to exclude the axe handles of legends, whose tag will be legend.
There might be other axes objects in your figure if it's more than just a simple plot. In such case, you need to add more conditions to identify the axes handles of the plots you are interested in.
To link a pair of figures with linkaxes use:
figure;imagesc(data1);
f1h=findobj(gcf,,’type’,’axes’)
figure;imagesc(data2);
f2h=findobj(gcf,,’type’,’axes’)
linkaxes([f1h,f2h],’xy’)
