This is my code,

 colors = ['r';'m';'b';'g';'c']; 
symbols = ['*-';'+-';'*-';'+-';'*-'];
 for k1 = 1:5
colsym = [colors(k1),symbols(k1,1:2)];
 plot(x, y, colsym)
 hold on
 end
 legend('-0.02','-0.01','0','0.01','0.02')

Thanks in advance.

Hello Priya, not sure how you have defined your y, so check out the code below:

 xCenter = 0;
 yCenter = 0;
 theta   = 0 : 0.01 : 2*pi;
 colors  = ['r';'m';'b';'g';'c'];
 symbols = ['*-';'+-';'*-';'+-';'*-'];
 for k1 = 1:5
    xRadius = k1;
    yRadius = 5/k1;
    x       = xRadius * cos(theta) + xCenter;
    y       = yRadius * sin(theta) + yCenter;
    colsym = [colors(k1),symbols(k1,1:2)];
    plot(x, y, colsym)
    hold on
 end
 legend('-0.02','-0.01','0','0.01','0.02')
