Hello and thanks in advanced!

I´m having problems ploting some data I receive from an OBR. The problem is that the data I receive comes separated, on the one hand I have the y axis data (50x1 double) and on the other hand I have the x axis data (4096x1 double). The problem comes when I try to plot because if I try to decimate the graph I get is not perfect do to 4096 and 50 not been multiples.

So as the data received in the x axis is not important i have tried to create my own x axis and here is where my doubt is. I need this x axis to have the same length as the y axis so I can plot them together but the x axis must have every digit of the array separated 0.5 cm.

y = transpose((0:1:49));

xaxis = transpose((0:0.5:length(y)));
