How to 'divide' the x-axis based on y-values?

Here's a sample equation plot:
x = linspace(0,100);
y = @(x) log(x);
plot(x,y(x),'-','LineWidth',2);
And I am attaching three pictures which represent what I would like to have. I want to 'divide' and 'categorize' the x-axis based on certain ranges of y values. Is there a way I can accomplish one or all three of the tasks outlined in attached picture?
Thank you

Hi,
There are really many and nice ways to take the desire output...here just one quick solution with some patches
x = linspace(0,100);
y = @(x) log(x);
plot(x,y(x),'--','LineWidth',2);
x_lim = get(gca,'xlim')
y_lim = get(gca,'ylim')
hold on
patch([0 0 exp(3.75) exp(3.75)],[y_lim(1) y_lim(2) y_lim(2) y_lim(1) ],[1 0.5 0.2],'FaceAlpha',0.2)
text(mean([0 exp(3.75)]),mean(y_lim),'y < 3.75','rotation',90,'FontSize',14,'HorizontalAlignment','center')
patch([exp(3.75) exp(3.75) exp(4) exp(4)],[y_lim(1) y_lim(2) y_lim(2) y_lim(1) ],[1 1 0.2],'FaceAlpha',0.2)
text(mean([exp(3.75) exp(4)]),mean(y_lim),'3.75 < y < 4.00','rotation',90,'FontSize',14,'HorizontalAlignment','center')
patch([exp(4) exp(4) x_lim(2) x_lim(2)],[y_lim(1) y_lim(2) y_lim(2) y_lim(1) ],[0.5 1 0.7],'FaceAlpha',0.2)
text(mean([exp(4) x_lim(2)]),mean(y_lim),'y > 4.00','rotation',90,'FontSize',14,'HorizontalAlignment','center')
grid minor
ylabel('ln(x)')

This is amazing. I am definitely going to try this out.
Is there any other way you can think of?
Thanks so much!
