I've got multiple vectors of which I would like to plot seperate histograms in the same figure. However, if I plot all histograms in the same 2D plot, the results become hard to interpret/distinguigh. Therefore I would like to plot them (detached) in 3D.
All I have right now is the following:
hist(A)
hold on
hist(B)
hist(C)
holf off
checkout bar3 for 3D bar plots.

How to plot a figure like this
The data is like f(x_i,t_j), i=1,2,..,M, j=1,2,...,N. The horizontal axis is time t and vertical axis is space x
I know that mesh gives a 3-D plot and surf also gives 3-D surface, I wonder which command can give the above 2-D figure?
To make a 2D heatmap, display your array as an image using imshow, and add a colorbar.
I wonder if anyone can help me to plot two 2D histograms on the same plot.
I do some lifetime imaging and I want to reproduce my result as histograms (phasor plot method). I know how to plot a single 2D histogram, but not more, without removing the preceding one.
I am currently using the DIPimage toolbox, but I have seen that for plotting 2D histograms you can use as well the function 'ndhist'.
Please, find attached the picture. This is not obviously what I am after, as the background should be all blue and I would like to plot more 'clouds' over the universal circle.
I work with MATLAB.
I have four matrices of size 10x3, and I need to plot them by using the area plot into three different layers, i.e. something similar to the contourslice example (https://uk.mathworks.com/help/matlab/ref/contourslice.html) where on the x-axis and y-axis I would have the 2-d area plot and on the z-axis the four matrices.
For example, I have the following three matrices with an area plot for each individual variable:
A=ones(10,3);
B=2*ones(10,3);
C=5*ones(10,3);
D=10*ones(10,3);
figure(); area(A,'DisplayName','HS')
figure(); area(B,'DisplayName','HS')
figure(); area(C,'DisplayName','HS')
figure(); area(D,'DisplayName','HS')
How can I layer there three area plots into one plot, as shown by this picture for example?
Thank you, Mat
Suppose I have a dataset which consists of three vectors which represent a trajectory in 3D. This temporal data can be plotted in Matlab with the following command:
plot3(Data(:,1),Data(:,2),Data(:,3),'.r');
The output is a "cloud" of points:
I would like to visualize the trajectory, so my question is: How do I modify the plot so that the color of the points represent the index (time) of the temporal data?
Just to make my point a bit clearer, imagine a trajectory of points that change color "smoothly" from red to blue in a way that will enable me to visualize the trajectory.
I can think of two answers:
use the surface function on a 3D line like this:
color=1:length(Data(:,1));
surface([Data(:,1);Data(:,1)],[Data(:,2);Data(:,2)][Data(:,3);Data(:,3)],[color ;color],...
'facecol','no','edgecol','interp');
this is a very nice trick, but it plots a line.
If you want to plot points, you can define an RGB color and plot single points with hold on like this:
hold on
for i=1:length(Data(:,1))
plot3(Data(i,1),Data(i,2),Data(i,3),'Color',[(i/100*255)/255 0/255 (255-(i/100*255))/255],'LineWidth',2)
end

I want to plot a 3d graph in matlab
By graph I mean in the sense of nodes and edges. I have an adjacency matrix as well as a coordinate matrix for every node. Eventually I would hope to colour these nodes and edges
The gplot function is only 2d. The scatter3 function does not allow for edges.
Any ideas?
plot3 allows you to plot points and edges in 3D.
It's now possible (MATLAB R2016b) to plot a node-link graph in 3d, using the graph class. Example:
g = graph(bucky);
plot(g, 'Layout', 'subspace3');
plot3 does not plot graphs, in the sense of nodes and links. I recommend to you igraph, but it scapes of matlab.
