I draw a best fit line
but I want to prolong it to x-axis, how to do this ?
I use this code:
figure;h=bar(val,n,'b');axis([-5 25 0 95]);grid onhold onA=[1;17]; B=[16;92];plot(A, B, 'go')%, 'LineWidth', 1, 'MarkerSize', 10);
coeffs = polyfit(A, B, 1);fittedX = linspace(min(A), max(A), 200);fittedY = polyval(coeffs, fittedX);plot(fittedX, fittedY, 'r-', 'LineWidth', 3);
how to prolong the best fit line ?
