splot of vector doesn't appear correct.

Hello: I am attempting to plot a vector in two segment.  The first segment is from (0.00000 0.00000 0.00000) to (0.63960 0.63960 0.42640).  The second segment is from (0.63960 0.63960 0.42640) to (0.70356 0.70356 0.46904).  A label, x', is to be placed beyond the second segment at (1.00356 1.00356 0.76904).  When I plot these segments with a view of 35, 225 degrees (set view 35,225,0.80000,1.80000), the label x' appears to be sitting on the second segment at about 1/3 the distance from the end. The label appears to be situated correctly; the second segment appears to be too long (but appears to start at the end of the first segment; the first segment, from other evidence, appears to end at the proper position).  The program and data sets follow; any help would be appreciate.  Thanks, Rich

PS: If there were a means of doing so, I would attach a postscript file of the result.
