thought was to have a simple filter that allowed the user to identify columns

you could apply other filters (such as Delaunay triangulation) to construct a
topology.<o:p></o:p></span></font></p>

<br>
Of course I know paraview cannot interpret the data; perhaps I should have said
"I was looking for a way to tell paraview that I have three columns of
data, and that they correspond to points in x,y,z space respectively.
Please plot the data". This is a simple enough request, provides all
the information necessary, but I could not find any UI that seemed designed for
this simple purpose.<br>
<br>
If there is not a simple way to plot such csv 3d data (as points in space, as a
surface, etc), I would think there should be. It seems a lot of data
would start in this very straight-forward format.<br>

You cannot expect ParaView to magically apply semantic meaning to the
columns of your data and generate a topology that is not nonsense (at least,
not without a lot of help). You have asked ParaView to read in a table (a
csv holds a table of data, no more, no less) and that is exactly what ParaView
has done. You can view the data in a spreadsheet-type view and you can
plot the columns of data.<u5:p></u5:p></span></font><o:p></o:p></p>

a data format that gives the topological nature of your data. If your
data is arranged in a 2D grid, you can store the data in a simple image format.
The simplest image format is just a 2D array written out as binary data
to a file (read in with the “Raw (binary) Files” reader).
ParaView also reads in .png files and it’s pretty easy to extend it to
read other image files.<u5:p></u5:p></span></font><o:p></o:p></p>

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:

<br>
I'm having a difficult time viewing what must be the simplest data set
possible. I have a csv file that includes 3 columns of numbers which I'd
like to view as 'elevation' type data: 1st two columns give x & y coord
(regular, though step-size for x and y are different), and 3rd column gives a
height (the data is actually error vs. 2 different params). I can open
the file, and see that it has read the columns of data correctly, but
can't get a plot of this surface.<br>
<br>
Seems this should be simple to view, but after blundering around the interface
for too long, it is not as obvious as one would hope.<br>
