How can i draw this plot?

Hi everybody I want to draw this plot exactly like the picture.

imshow(imread('f.jpg'))

Unfortunately, attaching the image did not work properly :(

There is nothing in the image.

The URL is:

https://www.mathworks.com/matlabcentral/answers/uploaded_files/1832982/f.jpg

However that apparently does not lead to anything.

The size may be a problem, so check that to be sure it is less than the 5 MB limit.

The second time also failed.

See if it works using the 'Picture' icon (the left-most icon in the 'INSERT' part of the top toolstrip).

Hi @S AsZ

Perhaps try this:

https://www.mathworks.com/help/matlab/ref/colormap.html#buc3wsn-1-map

sphere(100)
colormap copper     % select color scheme from the colormap library
shading interp
light
lighting phong

axis equal
xlim([-2 2])
zlim([-2 2])
view(0, 0)

I wrote this code but the output is terrible and I don't know how to fix it.

[x,y,z] = sphere;
figure
surf(x+2014,y,z+2) % centered at (2014,0,2)
hold on 
surf(x+2016,y,z+1)
surf(x+2017,y,z+1)
surf(x+2018,y,z+4)
surf(x+2019,y,z+1)
surf(x+2020,y,z+2)
surf(x+2021,y,z+2)
surf(x+2022,y,z+2)
surf(x+2023,y,z+4)
surf(x+2024,y,z+4)
surf(x+2025,y,z+1)
xlabel('Publication year');
zlabel('Number of publications');
colormap autumn % select color scheme from the colormap library
shading interp
light
lighting phong
view(0, 0)

Hi @S AsZ

If you want to display the statistical data on the number of publications over the years, wouldn't a bar chart be more effective?

Creating metallic spheres with an Nvidia-like ray tracing effect is unlikely to impress the presentation audience, journal editor or increase the acceptance chances of the manuscript. Furthermore, it can obstruct the other "sphere" like in the case of Year 2017.

I agree with you. Sphere chart is beautiful but using a bar chart is more sensible for this type of data. Thanks for your sphere code.
