[Paraview] plot over line

Hello, I had a similar problem in which was looking to plot the pressure on
the surface of a tube in a flow.
The way I did it was to 
Extract Block -> Connectivity -> Scatter plot.
The only problem with this was that it plotted starting at 120 degrees and
also I have the pressure over top and bottom overlaying each other, kind of
like it is plotted against x instead of along surface. It is also possible
to plot along a contour by selecting the points along a contour and
extracting selection and scatter plot. Note, I have so far been looking only
at 2D sets of data but I am sure can be used for 3D by taking a slice.

If I didn't include the Connectivity when extracting block it still plotted
however it jumped around the circle, which I think may be something to do
with my original mesh.

So I haven't quite got it doing what I want and look forward to when plots
along curved lines are available, if anyone else has any advice it would be
welcome.

Just to say it is also possible to open new viewer window with spreadsheet
and select extarcted selection or contour from drop down and then save this
as a .csv file which can easily be read plenty of other programs such as
Matlab for further data analysis.
