Resample issue with findpeaks

Hi,
I'm not sure what the issue is so I will post the code and hopefully someone knows what's going on. :D
x = 1:numel(y); y = data;
xx = 1:2:numel(y);
yy = spline(x,y,xx);
I want to resample the data then use the spline function and then use findpeaks do find maximum values. Here is the problem:
Let's say I plot(xx) or plot(yy). It only shows 50 values. If I plot (xx,yy) I get 100 values. This issue is messing up the locations and values of the peaks...I'm not sure how to solve this. Does that make sense?
Thanks you for any suggestions!

"Let's say I plot(xx) or plot(yy). It only shows 50 values. If I plot (xx,yy) I get 100 values." If size(xx) and size(yy) both are [1,50] then
plot( xx, yy, 'd' )
should give 50 points. However,
plot( [ xx, yy ], 'd' )
will give 100 points
