Dear experts -

I want to create a continuous 1D surface heatmap for every data point, with Distance (ft) in the X-direction and Temperature in the Y-direction. I have no idea how to do it. Please, can someone helps me with that.

Here I attached a sample of my data.

Thank you!

Maybe a colormap might work better if there is a difference between colormap and heat map.

在 MATLAB Online 中打开

data.xlsx

I'm not sure what a 1D surface looks like.

If Temperature is in the Y-direction, what variable should be used for the color of the surface?

Here I use all T0-T14 as the color data, Distance as X, and 1 through 15 as Y. Adjust as necessary.

data = readtable('data.xlsx','VariableNamingRule','preserve');

T = data{:,"T"+(0:14)};

X = data{:,"Distance (ft)"};

Y = 1:15;

surface(X,Y,T.')

axis tight

xlabel("Distance (ft)")

ylabel("1 - 15")

cb = colorbar();

cb.Label.String = "Temperature";
