can you upload content of Pdispatch and TimeValue also what error are you facing ?

Probably there must be categorical or other form of data for TimeValue matrix.

See this link for more info on how to plot then alike.

plot(TimeValue, Pdispatch(:, 1), 'r', 'LineWidth', 2); % Solar
is fine. plot() permits a positional linespec after x y pairs, and color letters are permitted in linespec . You would need 'Color' if you were setting a color by other methds such as RGB .

Ran in:
% Time array (24 hours)
TimeValue = 1:24;
% random data
SolarDispatch = 80 + 5*randn(1, 24);
WindDispatch = 50 + 6*randn(1, 24);
CoalDispatch = 100 + 7*randn(1, 24);
GasDispatch = 20 + 8*randn(1, 24);
HydroDispatch = 30 + 9*randn(1, 24);
Pdispatch = [SolarDispatch; WindDispatch; CoalDispatch; GasDispatch; HydroDispatch]';
I have taken random data like above , but your mat file can be different. please let me know if you are still facing issue. code seems to be ok.
figure;
subplot(2, 1, 1);
plot(TimeValue, Pdispatch(:, 1), 'r', 'LineWidth', 2); % Solar
hold on;
plot(TimeValue, Pdispatch(:, 2), 'g', 'LineWidth', 2); % Wind
plot(TimeValue, Pdispatch(:, 3), 'k', 'LineWidth', 2); % Coal
plot(TimeValue, Pdispatch(:, 4), 'b', 'LineWidth', 2); % Gas
plot(TimeValue, Pdispatch(:, 5), 'c', 'LineWidth', 2); % Hydro
title('Generator Dispatch Over Time');
xlabel('Time (hours)');
ylabel('Power Dispatch (MW)');
legend('Solar', 'Wind', 'Coal', 'Gas', 'Hydro');
grid on;

What does ‘not running’ mean? What is not working correctly?
When I supply values for ‘TimeValue’ and ‘Pdispatch’ it runs without error —
TimeValue = 0:23;
Pdispatch = rand(24, 5);
figure;
subplot(2, 1, 1);
plot(TimeValue, Pdispatch(:, 1), 'r', 'LineWidth', 2); % Solar
hold on;
plot(TimeValue, Pdispatch(:, 2), 'g', 'LineWidth', 2); % Wind
plot(TimeValue, Pdispatch(:, 3), 'k', 'LineWidth', 2); % Coal
plot(TimeValue, Pdispatch(:, 4), 'b', 'LineWidth', 2); % Gas
plot(TimeValue, Pdispatch(:, 5), 'c', 'LineWidth', 2); % Hydro
title('Generator Dispatch Over Time');
xlabel('Time (hours)');
ylabel('Power Dispatch (MW)');
legend('Solar', 'Wind', 'Coal', 'Gas', 'Hydro');
grid on;

Make sure that your TimeValue and Pdispatch variables are correctly defined and contain the necessary data, and this code should work as intended in a MATLAB environment.
