@Image Analyst makes me laugh!
@Abderezak, you will get good help here, but you will need to be more specific.

Since you didn't provide the data for the random-looking graph, this maybe not what you are looking for, but it is a very simple example for turning a nonlinear graph into a linear one.
x = -10:0.1:10;
y = x.^2;
X = log(x);
Y = 2*X;
subplot(2,1,1)
plot(x, y, 'linewidth', 1.5)
grid on
xlabel('x')
ylabel('y')
title('y = x^2')
subplot(2,1,2)
plot(X, Y, 'linewidth', 1.5)
grid on
xlabel('log(x)')
ylabel('log(y)')
title('log(y) = 2*log(x)')
