trying to create contour 2D from tabular data
Hi,
I'm new here and I'm also new as a tecplot 360 user. I have a file .dat with 3 columns of numbers, thickness as function of two other indipendent variables. I have loaded the data file as a General text and I have plotted the 3D view but now I need to view the 2D contour plot and I don't understand how do that. Everything I have tried give to me the same results ... a white graphic with only the right axes .. :( thanks for your help 
help contour 2d  "connect" the data
Tecplot is unable to create a contour plot from data that is "unconnected" (which is what your data are). One can connect data in Tecplot a variety of ways. Once Tecplot understands the connectivity of the data, then it will be able to produce the contour.
Option 1.  If the data are 2D one can triangulate via a method described in this tutorial video: http://www.youtube.com/watch?v=3FMTLQozKA Option 2.  If the data are on a regular XY grid, one can create a grid in Tecplot Data>>Create Zone>>Rectangular and then interpolate the data onto the newly created grid Data>>Interpolate Cheers, Scott 
Thank you very much!! Now I can see the contour of my data. :o

Hello,
my problem is as follows: i have data velocity magnitudes in an excel table. Each cell has a coordinate (x,,y) which is associated with the location in space where the velocity was measured. v=f(x,y). How do I import the data correctly? Until now i had no success. I have imported the data from excel (table size 21*31) gotten 21 variables in tecplot. Crated rectangular zone and interpolated. Unfortunately i can only plot contour where my x and y axes are one of those 21 velocities columns and can choose a third one to do the colouring with. thank you very much. 
Hi.. I need a bit of help in contouring of temperature data on a 2d surface. Guess you could advise.
I have loaded data into tecplot from an excel file, the data is irregular (called Iordered) in tecplot. I am not able to find an option for "triangulate" under the data menu. And creating a rectangular zone, when I try to get the contour, it assigns the entire surface to a value "zero". Which is the correct way, triangulate or creating a zone to interpolate? Why do I not see the triangulate option on my window? Could you please suggest where I might be going wrong? Will be of great help, thanks. :) 
Older versions of Tecplot 360 EX do not have the ability to perform a 2D triangulation via the GUI (it can be performed via a macro though). However the latest version of Tecplot 360 EX 2015 does have the triangulation capability, and it can be found under the menu bar Data>>2D Triangulation.
If possible, I would recommend updating to the latest version – here is a link to the Tecplot download page: http://www.tecplot.com/my/productreleases/ . Regards, Scott
