cfit object as Data on line

Hello,

i am solving problem. I am using graphs in GUIDE like this:

handles.lines.firstLine_bezmod = line('Parent',handles.axes_realbezmod,'XData',handles.glob_xdata_bezmod,'YData',handles.glob_ydata_bezmod,'Color','b','LineStyle','o');
handles.lines.secondLine_bezmod = line('Parent',handles.axes_realbezmod,'XData',handles.glob_xdata_bezmod,'YData',handles.glob_z,'Color','r','LineStyle','-');

I have also handles.lines.thirdLine_bezmod and I need to put there a cfit object called fitresult (from curvefittingtoolbox) as a data (something like this ->

 handles.lines.thirdLine_bezmod = line(fitresult ... )

How can I handle this problem?

Thanks.
