Dont know how to make a plot using for loop

1 view (last 30 days)
so i have to create a plot that relates a set of variables against a time variable, but for that i need a for loop, because it has to go through multiple numbers, but i can code the for loop part.

Can you share the code for time_domain_longRR? Or at least describe the input and output variables' classes and sizes? Where/what is the time variable you want to plot against, and what variables to you want to plot against it?

It depends on how your time and data are stored, but you can always use the hold command to sequentially add plots in a for loop:
figure;
for (i = 1:10)
hold on;
plot(t, data(:,i));
hold off;
end

As per my understanding, you wish to plot a set of variables against time axis.
Assuming 't' contains the time data and the gathered data pNN50_1 is a 1D array, you can directly plot as shown below:
figure
plot(t, pNN50_1);
If pNN50_1 is set of variables or a 2D array you can use either of the below methods:
figure
hold on
for i=1:length(t)
plot(t,pNN50_1(:,i)); %use plot(t,pNN50_1(i,:)); if data is present in rows
end
hold off
OR
figure
plot(t,pNN50_1); %the plot contains one line for each column in " pNN50_1”
% if data is present in rows, use plot(t,pNN50_1');
Refer to the below documentation for more information on “plot” function.
Hope this helps!
