Hi community,

Thanks

@Abdelkader Hd, these plots require either some maths or the data point needed to create them. Can you provide the data as labeled in the x- and y-axes?

@Sam Chak Thanks for your time, for example I have F is a function of x and y (F(x,y)). I need just the code used on matlab to plot a density

Answer 1

Try the function contourf:

x = linspace(-2*pi,2*pi);
y = linspace(0,4*pi);
[X,Y] = meshgrid(x,y);
Z = sin(X) + cos(Y);

figure(101);
contourf(X,Y,Z,100, 'edgecolor','none');
colormap hot; % use colormapeditor for a customised colormap

@M.B thank you sir for your help

https://www.mathworks.com/help/matlab/ref/histcounts2.html can be used to calculate the counts for density plot purposes. imagesc() with the appropriate colormap and colorbar(). Use tiledlayout to arrange the plots.
