Plotting trajectory of variation of two population with the time

I have this differential equation that describes the variation of two populations:

function [dxdt]= raueber(t,x,m)
dbdt=x(1)^1*(1-x(1))-x(2)*x(1);
drdt=x(1)*x(2)-m*x(2);
dxdt=[dbdt; drdt];

I already solved the ODE with:

[time,x_result]=ode15s(@raueber,tspan,X0,'',m1); 
dxdt = raueber(time,x_result,m1);

and before I gave all the parameters and values.

Now I'd like to plot the trajectory, wich means B on the x-axes and R on the y-axes. I tried:

plot(x_result(1), x_result(2))

but it's not worthy.. any suggestion?

plot(x_result(:,1),x_result(:,2))
