[Paraview] PV 3.80. understanding plot over line

[Utkarsh Ayachit]

By default the x-axis is the arc-length, which is measured as the sum
of lengths of line segments from the first point, hence it goes from
0-14.

When you change the "X Axis Data" to "Use Data Array" and pick "Points
(1)" you should indeed get the x-axis to range from [-7, 7] unless
your probed data doesn't have any values for y < 0.

I created a wavelet source with default values and the them probed
with a line (0,-7, 0) - (0, 7, 0), and the x-axis (after changing to
Points(1) ) is indeed [-7, 7].
