I am trying to read data from file. Now i would like to read first suppose n=337 lines and plot the data for the same, now repeat same for the next 337 lines and untill the end. Now i would like to make movie of the graphs\plots with same x and y axis generated into single mvi file.
T=readtable('Plug.txt','ReadVariableNames',true);
F = scatteredInterpolant(T.XC, T.YC, T.VY);
[xmin, xmax] = bounds(T.XC);
[ymin, ymax] = bounds(T.YC);
x0 = linspace(xmin, xmax, 409);
y0 = linspace(ymin, ymax, 337);
[xq, yq] = meshgrid(x0, y0);
zq = F(xq, yq);
this is how i am planning to go ahead with reading the file but how to loop and save all the plots into animation. One of the static images can be found below but what i want is that movie whcih procceds with first showing y=0 data and then y=1 y=2.... till y=87.

T=readtable('https://in.mathworks.com/matlabcentral/answers/uploaded_files/1106475/Plug.txt\Plug.txt','ReadVariableNames',true);
x = T.XC ;
y = T.YC ;
vy = T.VY ;
xv = unique(x) ;
yv = unique(y) ;
nx = length(xv) ;
ny = length(yv) ;
figure(1)
filename = 'test.gif';
for i = 1:ny
plot(x(y==y(i)),vy(y==y(i)))
ylim([-8 1])
drawnow
frame = getframe(1);
im = frame2im(frame);
[imind,cm] = rgb2ind(im,256);
if i == 1
imwrite(imind,cm,filename,'gif', 'Loopcount',inf);
else
imwrite(imind,cm,filename,'gif','WriteMode','append');
end
end
