How to build a graph from two graphs at certain intervals

Hi, i have some problem I need to build a schedule of two graphs in simulink I have a graph y1 and y2 but I need 1 graph which will be composed like this:   on the interval (0;t1) there will be a function y1 on the interval (t1;t2) there will be a function y2 and on the interval (t2;t3) there will be a function y1 again t1, t2, t3 some numbers

for example, I have a function (y=sinx) that should be built on an interval from 0 to 1 and there is still a function y=

5 that is built from 1 to 2

what block in Simulink can do it? Or what can be done?

From the diagram, it seems that it can be achieved by using a Switch block. Compare y1 with zero using a Relational Operator block. If it is true, pass y1. Otherwise, pass a constant of 5. y1 can be generated using the Sine Wave block. You will need to adjust the frequency.
