MATLAB: Axes problem in a plot

Question

how can i solve the problem of this two images automatically without having to fix the axes range for each plot (i have millions of these plots)?

(problem: axis shoud be for x[0 18]) and for y[-6 6]

(problem: the minimum x and minimum y should be bigger)

thank you so much.

Answer 1

You can set the axes limits to be a certain percent of the data or fixed values, depending on what you want.

x = -pi:.001:pi;
y = sin(x).*x.^2;
plot(x,y)
axis([-5 5 -6 6])  % Use this to set the limits as needed
