How to change plotted graph's line?

I have two matrices which are 200*5 and 201*5. I want to plot a graph from these two matrices. as X component is from the one, Y component is from the other. I have an algoritm below. When I select the line as a star (*), it is plotted but I want it as a line. How can I do it? Thank you.

%for plotting
    [row col]=size(Vdt);
    for m=1:col
        for n=1:row-1
            hold on
            plot(t(n,m),Vdt(n,m),"*")
        end
    end

If you leave the marker symbol off, the plot command will default to using a solid line with no symbol. You can also just explicitly specify a solid line with no symbol:

plot(t(n,m),Vdt(n,m),"-")

You can read more in the documentation for the plot function, in particular this example (and ones following) from that same page.

It doesn't work. I tried it. I think, since ,in the plot command, the x and y components are selected as a point, the plot does not plot the graph as a line. Thank you.

Sorry, I did not read your code closely enough.

The problem is that you are not plotting vectors. Each call to the plot function is plotting just a single point, so there is no "line" for the plot command.

Instead, you need to structure your code so that you are plotting all the point of each line in a single plot command, instead of looping over each point. It might be like this:

%for plotting
figure
hold on
[row col]=size(Vdt);
for m=1:col
    plot(t(:,m),Vdt(:,m),"-")
end

If that connects the wrong set of points, then you should loop over n instead of m.

If you post your data, it would be easier to know for sure.

The matrices is in attachments. There is zero values in the matrices and I want to match the Vdt values to the t values correctly. So that I write a algorithm like that. Thank you.

I don't understand what you mean by "match the Vdt values to the t values correctly".

That part of your algorithm is completely unrelated to the question you asked here. I suggest you open a new question about the algorithm. You should add more detail about exactly what you are trying to do.

Okey, thank you. I think I must change structure of my code.

Another possibility, if the points are generated one at a time, is to use some of the animation techniques available in MATLAB, like creating an animatedline and using addpoints to add points to the line as they are calculated or creating a normal line with line or plot and adding values to the line's XData and YData properties as they're calculated.

That's good idea also. Thank you.
