help with a heat map
显示 更早的评论
Hello, I have been trying to create a heat map with the following characteristics: variation of the magnitude of the increase in vertical effort in a mesh every 1 cm for point, linear, and distributed rectangular loads. I am a civil engineer and hope you can help me.heat map

hello
can you share your data / code - or a sketch / image / publication of what you want to achieve ?

I assume you've looked here: https://www.mathworks.com/help/matlab/ref/heatmap.html
You either need a matrix of data corresponding to every point in your grid, or vectors corresponding to the x and y locations, along with their magnitude. This should include a value for every location.
x = [1 2 3 4];
y = [1 2 3];
% len(y) = # rows in Z
% len(x) = # columns in Z
Z = rand(length(y),length(x));
heatmap(x,y,Z)
Hi @Camila
Perhaps this heatmap will help you to understand the data visually. In the strictest definition, a heatmap is a tabular representation in grid form where numerical values are visualized using colors instead of numbers. If your table or grid contains NaN values to represent missing data, the colors of the affected cells will be darkened.
x = [1 2 3 4];
y = [1 2 3];
[X, Y] = meshgrid(x, y);
z = X.*Y;
figure(1)
h1 = heatmap(x, y, z);
figure(2)
h2 = heatmap(x, y, z);
h2.CellLabelColor = 'none'; % Turn off numerical display

hello
there are a couple of interesting Fex submission :
and probably many others ...
