I want to draw the pole-zero map of the specific system. This is my code:
-------------
close all;
clear;
clc;
w0=300;
l1=2*w0;
l2=w0^2;
k=60;
s=tf('s');
r=[0.9,1.2,1.3,1.4,1.8,2.5,3.5];
H=figure;
for i=1:7
transfer_function=k*(s^2+l1*s+l2)/(r(i)*s^3+r(i)*(l1+k)*s^2+(k*l1+l2)*s+k*l2);
pzmap(transfer_function)
hold on;
end
s=findobj(gcf,'Type','Axes');
title('');
set(s,'XLim',[-300,0],'YLim',[-60,60],'XColor',[0,0,0],'YColor',[0,0,0],'XGrid','off','YGrid','off','GridLineStyle','--','YTick',[-60 -40 -20 0 20 40 60]);
set(s.XLabel,'FontSize',12,'FontName','TimesNewRoman');
set(s.YLabel,'FontSize',12,'FontName','TimesNewRoman');
linewidth=1.5;
set(s.Children(1).Children(1),'LineWidth',linewidth,'Color','#ESAD00');
set(s.Children(1).Children(2),'LineWidth',linewidth,'Color','#7C6FAF');
set(s.Children(2).Children(2),'LineWidth',linewidth,'Color','#AA7816');
set(s.Children(3).Children(2),'LineWidth',linewidth,'Color','#EE6C1B');
set(s.Children(4).Children(2),'LineWidth',linewidth,'Color','#E02F12');
set(s.Children(5).Children(2),'LineWidth',linewidth,'Color','#75AB43');
set(s.Children(6).Children(2),'LineWidth',linewidth,'Color','#238392');
set(s.Children(7).Children(2),'LineWidth',linewidth,'Color','#0728E4');
grid on;
legend('r=3.5','r=2.5','r=1.8','r=1.4','r=1.3','r=1.2','r=0.9');
------------
I tried to usd 'pzmap' and 'pzplot' to draw the graph, and once the 'grid on' and 'legend' are used. The grid and the number which is undired, look this picture. And the legend is linear which is not 'x'.
I want to draw a graph like this:
How should I do?

Fixing the 'ES' to 'E5'...
