MATLAB: Plot and scatter plot, weird lines removal

plot

Hi!

I have a plot and another scatter plot in same window, but i get weird lines between the scatters. How can i remove those? My code is:

plot(g,f), grid on, hold on

scatter(g_v,f_v)

xlabel('g(s)=c(s)*s')

ylabel('f(s)=q*EBO(s)')

%f true
  plot(g,f,'+');

Use a marker in the plot function By default plot uses a continous line

You could just blur the heck out of it with conv2(). Or else use the image to model a perfectly smooth function, like a quadratic or something. I used polyfitn for this but John removed it from the File Exchange. Maybe you could try this instead: http://www.mathworks.com/matlabcentral/fileexchange/13719-2d-weighted-polynomial-fitting-and-evaluation

Hello,

The command 'hold on' will retain the existing plots on axes.

scatter()
hold on
plot()
