How can i connect different points using straight line after plotting? is there any plotting tool?

How did you plot your points? The plot or line functions will, by default join points with a line.

Thanks for replying. actually i am getting single point for every iteration. I just want to connect them(all those point) through line at the end

Try this with your data

plot(x, y, 'b*-', 'LineWidth', 2, 'MarkerSize', 15);
grid on;

is writing a command is necessary?. isn't any tool in figure to do same task

I don't know as I do all my interaction with MATLAB through programming rather than interactively. From your reply to Adam, it also sounds like you have a program, so what's the big deal with just adding a plot() call to your program?

Are you plotting those in a loop? If you are, index the variables and then plot at the end of the loop:

x = 5:8;
for k1 = 1:length(x)
    y(k1) = 16 - (x(k1)-7).^2;
end

figure(1)
plot(x, y, '-',  x, y, '.')
