Hello Sarunas,
I understand from your query that you need assistance with finding the root locus. Unfortunately, the image you have shared is no longer accessible.
I assume that you have a Single-Input, Single-Output (SISO) system defined either as a continuous-time or discrete-time LTI system or identified LTI model. You can use the “rlocus” function to obtain the root locus plot of your system as shown in the code snippet below:
sys = tf([1], [1 0 1]) % defining the system
rlocus(sys)
Here is the obtained output:

Kindly refer the following documentation to learn more about “rlocus” function:
Hope this helps,
