Nikola - there are probably several ways to do this, so here is one that you should be able to adapt for your purposes. Suppose that we wish to draw 100 points of the sine wave, from -2pi to +2pi, and see the curve "grow" over time. We could do this as follows
% generate the sine data
x = linspace(-2*pi,2*pi,100);
y = sin(x);
% create the figure and an empty plot graphics handles
figure;
hPlot = plot(NaN,NaN);
% set the limits
xlim([min(x) max(x)]);
ylim([min(y) max(y)]);
% draw the curve
for k=1:length(x)
% update the data
set(hPlot,'XData',x(1:k),'YData',y(1:k));
% pause for 0.1 seconds
pause(0.1);
end
Rather than calling plot a multiple of times, which will create multiple graphics handles, we just call it the once and then update its x and y data on each iteration of the loop, adding one more point at at time. Try incorporating the above into your code and see what happens!
