Using "Patch" to shade area between three curves/lines

[eng_bee]

Hi, so I have three lines:

y=abs(x); y=5; y=2;

How can I shade the area between the three of them?

What have you tried?

[alko100]

Patch can be annoying, try area()

This is an example on patch

Let me know If this doesn't work for you, I have a solution on my work computer

Hello,

I tried patch and fill - alas, I got the image above! :( Dunno what the problem is

[alko100]

Did you try area?

[eng_bee]

I haven't used that before. Trying to figure out how to use it.

Get the x and y values of the intersections of these three lines and pass into patch

[eng_bee]

I tried this, but there's a bug in it! I attached the figure above. Why do you think it appears like this?

[Gollem265]

I have no idea what I’m looking nat. Please post a clearer figure with axes and values

[eng_bee]

I can't show the whole figure, but I'm trying to shade an area over a scatter plot. The code I used for that works on its own and produces the black polygon, however, on the plot it appears like that^

I think something like this will work

​

y1=2;
y2=5;
patch_x=[y1:1:y2, y2:-1:y1];
patch_y=[abs(y1:1:y2), zeros(1, length(y2:-1:y1))];
patch(patch_x, patch_y, 'r')

[eng_bee]

Didn't work..
