so whats the problem here?
someComplex=rand(5,1)+1i*rand(5,1)
plot(someComplex,'x');
set(gca,'YScale','log');
xlabel('real part');
ylabel('imaginary part (i)')

Currently, there is no direct function to plot one of the axis in log scale. As a workaround, you can set the appropriate scale to "log" as follows,
lamda = -rand(3,1)+1i*rand(3,1) % create three random set of eigenvalues
plot(lamda,'o','LineWidth',3)
set(gca,'YScale','log')
grid on;
If you want to set the real part in log scale, use the following line of codes instead,
plot(lamda,'o','LineWidth',3)
set(gca,'XScale','log')
grid on;
Both X and Y coordinates are plotted in log scale using "loglog" function as follows,
loglog(lamda,'o','LineWidth',3)
grid on;

"Currently, there is no direct function to plot one of the axis in log scale." thats not true, look into semilogx() and semilogy()
