Combine 4 graphs into 1

To the Matlab Community.

For a university exam, I'm trying to create a code that allows me to plot in a single graph four functions (in four different variables) with different domains.

The resulting graph of the four functions combined, for how the functions are defined, should present, in the jump points between the variables, a continuity. Unfortunately, I do not see a result like that.

In the attached file, there are the functions and the variables. For clarifying:

1. v1(x1), with 0<x1<value(1)
2. v2(x2), with value(1)<x2<value(2)
3. v3(x3), value(2)<x3<value(3)
4. v4(x4), value(3)<x4<value(4)

What I would like to get is a graph of the function v1, v2, v3, v4 as functions of the same parameter x, with 0<x<value(4).

Thanks in advance for the help.

I don't really understand your question. Can you upload a sketch of your desired graph?

Thank you for your interest in my question ... I've just managed to figure out where I was wrong.

In imposing the boundary conditions for the creation of the 4 functions, I applied the boundary conditions considering as if there were 4 distinct functions.

It is obvious that then the functions, when I tried to merge them into a single chart, turned out to be not continuous.

just alter it as mentioned below:(see attached screenshot)

figure
plot(x1,v1(x1),'Color','r','LineWidth',2)
hold on
plot(x2,v2(x2),'Color','g','LineWidth',2)
plot(x3,v3(x3),'Color','b','LineWidth',2)
plot(x4,v4(x4),'Color','y','LineWidth',2)

You’re welcome good that you found out the reason
