I am creating some figures in MATLAB and automatically save them to files. The problem that by definition the images are small. A good way to solve my problem by hand is to create an image (figure)...

When I add grid lines to a log plot, it seems to automatically add every possible grid line, and I would like to only include the major lines. I tried turning the minor ticks off, but it has no eff...

I need to make a .fig file that can be reopened in Matlab, but I am working in Octave. But apparently there is no saveas command in Octave. This is what I am trying: octave:3> plot([1,2,3],[45,...

I have a database P with columns X, Y and Z: x=0:1:50; r=3.*rand(1,51); P=[cos(x')+r',sin(x')+r',sin(x'+r').*cos(x')+r']; P = sortrows(P,[1,2]); N = 500; xv = linspace(min(P(:,1)), max(P(:,1)), N);...

I plot a horizontal boxplot in MATLAB -- boxplot(y, group,'orientation','horizontal'), and then hide the y-axis using set(gca,'box','off','ycolor','w'). It looks fine on the screen - only the bott...

I want the color of each arrow in a quiver3 plot from MATLAB to correspond to the magnitude of each arrow. Is there any way to do that? I saw a few examples online that are able to do this for th...

I find the amount of whitespace around plots in both normal Python Matplotlib and Matlab quite annoying, specifically the left and right margins that make your plot look tiny when inserting the sav...

I'm using a Matlab Live script in which I'd like to use some subfigures. As the Standard figure size only uses a small section of the screen widths, I tried to enlarge the figure as follows: h = f...

I want to create the 3D plot of the probability density functions of my variable. I have a matrix with dimensions 189x10000, where rows correspond to the time and columns are results of the simulat...

If I do a bar([1 2 3 4 5;2 3 4 5 1], 'stacked') I get two bars of stacked values corresponding to the two rows of my data - as I expected: I would like to be able to similarly plot a stacked b...

Let's say data is a matrix of size 129 * 129. by using mesh(data, 'FaceColor', 'none', 'EdgeColor', 'black') we get something like We can find that the grid are quite intense. I would like t...

Is there an option to change the symbol size in the legend that Matlab creates? I only want to increase the symbol size in the legend. I have used 4 scatters of 3 points each.

I have a data set that looks like this 140400 70.7850 1 140401 70.7923 2 140402 70.7993 3 140403 70.8067 4 140404 70.8139 5 140405 70.8212 3 Where the first column corresponds to time (one...

I find that data points that lie on or near the axes are difficult to see. The obvious fix, of course, is to simply change the plot area using axis([xmin xmax ymin ymax]), but this is not preferabl...

I'm trying to fill an area between two curves with respect to a function which depends on the values of the curves. Here is the code of what I've managed to do so far i=50; cc = @(xx,x,y) 1./(1+(e...

MATLAB 2016a introduced Live Scripts, allowing to show plotting output next to the script. Is it somehow possible to show animations? For example, the following code in a regular script will plot a...

I got a for i=1:15. Inside I generate a variable d=1:0.01:10, which is the x'x axis and based on this, I create a continuous function F(d) which has 2 unique variables pitch and yaw. I then plot th...

I have the following problem: in my MATLAB code I use statements like figure(1) to change destination figure for some data. The problem is that after this MATLAB take system focus on the ...

MATLAB provides the addlistener function. Listeners allow us to keep track of changes of an object's properties and act upon them. For example, we can create a very simple listener that will displ...

In MATLAB I have a graph with some tick labels. I'd like to visually emphasize a few of these labels, but not all of them. Is there a way to only put SOME tick labels in boldface?

the code figure scatter([1,2,3],[1,2,3]); ax = gca; ax.YDir = 'reverse' ah = annotation('arrow','position',[ 2.5 2.5 -1 -1]); set(ah,'parent',ax); gives a wrong vector head alignment: Any ide...

I'm attempting to plot a color gradient which I would like to be uniform along an axis (in the case of the picture below defined by the angle pi/7) When I use the patch command, The plot matches t...

I want to add a x-axis line at 0 to a Matlab figure so that I can compare my data to see if it is positive or negative when saving the figures to a jpg. What is the best way to do this? I know you ...

I'm clueless when it comes to which renderer to use for MATLAB figures or when it matters, but I have come across certain examples where it does matter: plot(0,0,'ko','markersize',50,'linewidth',8...
