MATLAB: How to display the data points on the graph

Question

filename='data3.txt';

headlines=0;

delim='\t';

B=importdata(filename,delim,headlines);

t=B(:,1);

y=B(:,2);

fun = @(x,t)x(1)*t.^3 + x(2)*t +6;

x0=[1 1];

x=lsqcurvefit(fun, x0, t, y);

scatter(t,y);

fprintf('Function fitted is y = %5.3f x^3 + %5.3f x + 6\n', x(1), x(2));

fplot(@(t)x(1)*t.^3 + x(2)*t +6, [B(1,1) B(10,1)]);

The above is my code. The scatter command works as usual when I get rid of the fplot command, but fplot seems to overwrite the scatter part and does not show me the data points anymore.

Thanks in advance.

Add a hold after your scatter plot:

scatter(rand(10,1), rand(10,1));
hold on
fplot(@(x) x, [0 1])
