This is one way
data = readtable('load.xlsx');
month_names = data.Properties.VariableNames(2:end);
x = 1:numel(month_names);
y = data.Hour;
z = data{:, 2:end};
ax = axes();
[X, Y] = meshgrid(x, y);
surf(X, Y, z)
ax.XTick = x;
ax.XTickLabel = month_names;
ax.XTickLabelRotation = -45;
In case you need to plot lines
data = readtable('load.xlsx');
month_names = data.Properties.VariableNames(2:end);
x = 1:numel(month_names);
y = data.Hour;
z = data{:, 2:end};
ax = axes();
[X, Y] = meshgrid(x, y);
plot3(X, Y, z)
ax.XTick = x;
ax.XTickLabel = month_names;
ax.XTickLabelRotation = -45;
grid on
