Add more data and draw a line through the points

Hello, I have created a function and each time it gives me a point of data. I use hold on/hold all for plotting these results and I obtain a series of points. Is there a way to join this points through a line for the final plot? Thanks in advance.

Stored the results of calling your function in an array and then just plot the whole array of results in one instruction afterwards.

Result = zeros(1, 100);
for k = 1:100
  Result(k) = rand;   % or your external function
end
plot(Result)

Or if there is any good reason to create the diagram in steps:

figure;
axes;
LineH = line(1, 1);
for k = 1:100
  YourSubFunction(LineH);
  pause(0.02);
  drawnow;
end

function YourSubFunction(LineH)
oldX = get(LineH, 'XData');
oldY = get(LineH, 'YData');
X    = rand;
Y    = oldY(end) + 0.5 + rand;
set(LineH, 'XData', [oldX, X], 'YData', [oldY, Y]);
end
