Plot works just fine
[ax,p1,p2] = plotyy(t,P3_FzInv,t,T4_T3,'plot');
grid on;
% [ax,p1,p2] = plotyy(xaxis,T4_T3,'r-',xaxis,P3_Fz,'b-','LineWidth',2);
% [ax,p1,p2] = plotyy(t,z1,'r-',t,z2,'b-','Linewidth',2);
%set(h,'FontSize',7,'Location','best')
xlabel(ax(1),'seconds');
ylabel(ax(1),'P3 <<--- Power Site --->> Fz');
ylabel(ax(2),'T3 <<--- Power Site --->> T4');
title(File2VarTitle);
set(p1,'LineWidth',2);
set(p2,'LineWidth',2);
FigHandle1 = figure(1);
set(FigHandle1, 'Position', [100, 100, 1700, 300]);
Ginput seems to have a problem
display (' Go to Figure (1) ');
display (' LEFT BUTTON + SHIFT to select a region, then ENTER ');
[TrajX, TrajY] = ginput;
ginput worked great for quite a while,now it doesn't work. TrajX and TrajY give a single number, not the string I used to get. What happened? Did we get a rewrite to the ginput function?

Don - according to ginput, there doesn't seem to be any changes to the output of ginput. Have you recently changed versions of MATLAB? Which version are you using? Why do you say that this function used to return a string and yet are expecting two outputs? Please clarify.

was using R2015b successfully, then upgraded to R2016b and it quit working. When it worked, I got the selected string and the rest of the program executed properly

Return has always been documented as terminating the input early, since the days of R13 at least.
It does not matter to ginput whether the user shift-clicks or not: they just need to click in two places and then press return. Or you could use
[TrajX, TrajY] = ginput(2);
Or perhaps it would make more sense to use imrect

No shift-click needed any more It works great now. They changed the Matlab in 2016 and didn't tell me, I guess
