What you are doing is reading in point data, and displaying this point data in 3d space. You have not created a solid for ParaView to color – just points.<BR>
<BR>
I believe what you want to do is actually create a solid. This can be done using the “table to structured grid filter”. Turns out that I had this question from a user earlier today, and wrote up a quick and dirty wiki page on it, located here: <a href="http://www.paraview.org/Wiki/Data_formats">http://www.paraview.org/Wiki/Data_formats</a><BR>

</SPAN><FONT SIZE="4"><SPAN STYLE='font-size:13pt'>Hi,<BR>
<BR>
I'm quite new to Paraview and have an urgent problem. I employed the help that was/is available to me - meaning <a href="http://paraview.org/OnlineHelpCurrent/">http://paraview.org/OnlineHelpCurrent/</a> - but couldn't solve the problem until now. Actually, I don't consider my problem to be really complicated, it might well be that the solution is one mouse-click away.<BR>
<BR>
APPROACH<BR>
--> a dataset (CSV-file) of a three dimensional tomography was imported into Paraview<BR>
--> 'table to points'-filter was performed, using the x-,y- and z-values (latter are negative) of my dataset (first three columns)<BR>
--> 'colour by...': the fourth data column with the resistivity values was chosen<BR>
-|-> finally I wanted the colors to be interpolated between the points.<BR>
<BR>
<BR>
PROBLEM: I can't perform the color interpolation.<BR>
<BR>
In the wiki there's a small picture showing the color section with the option 'color by...'. Above this dropdown-list you can see 'interpolate colors"<BR>
being activated.<BR>
<BR>
<a href="http://paraview.org/OnlineHelpCurrent/Display.html">http://paraview.org/OnlineHelpCurrent/Display.html</a><BR>
<BR>
In my case, there is no such thing, instead the option ist named 'interpolate scalars'. In addition to that, in my display there's a second (smaller and empty) dropdown-list next to 'color by...' and an option called 'apply texture: none' (grey).<BR>
<BR>
<BR>
Many thanks in advance if you can help me! (unfortunately I can only answer tomorrow and then not until next monday, 26th July)<BR>
