How to remove start and endpoint line?

I would like to remove contecting line between start and End point.

My script as below.

%% Plot Freq vs ErMag
figure; hold on;
xEval = TFAOut(strcmp(TFAOut.UserComp,'Eval'),:).Freq;
yEval = TFAOut(strcmp(TFAOut.UserComp,'Eval'),:).ErMag;
xCtrl = TFAOut(strcmp(TFAOut.UserComp,'Ctrl'),:).Freq;
yCtrl = TFAOut(strcmp(TFAOut.UserComp,'Ctrl'),:).ErMag;
plot(xEval,yEval,'r-',xCtrl,yCtrl,'b-');
grid on;

Introduce NaN at the end of the line.

Can you show me how?

Assuming your data is 1D row array:

xEval = [xEval NaN] ; 
yEval = [yEval NaN];
xCtrl = [Xctrl NaN];
yCtrl = [yCtrl NaN] ; 
plot(xEval,yEval,'r-',xCtrl,yCtrl,'b-');
