Hi I am newbie of data tank.
I was wondering if is it possible to draw a 3D Graph from a set of points.
I have this set of data that I've formatted for gnuplot

1.0 2.4 -11.24231971
1.2 2.4 -11.25968094
1.4 2.4 -11.26959253
1.6 2.4 -11.27251165

1.0 2.2 -11.24602632
1.2 2.2 -11.25725795
1.4 2.2 -11.26361698
1.6 2.2 -11.26491732

1.0 2.0 -11.25444859
1.2 2.0 -11.25915341
1.4 2.0 -11.26111529
1.6 2.0 -11.25957314

1.0 1.8 -11.26663156
1.2 1.8 -11.26718655
1.4 1.8 -11.26418234
1.6 1.8 -11.25978561

1.0 1.6 -11.28141559
1.2 1.6 -11.27765546
1.4 1.6 -11.27111275
1.6 1.6 -11.26443029

1.0 1.4 -11.28584316
1.2 1.4 -11.27838879
1.4 1.4 -11.26839513
1.6 1.4 -11.25954647

is it also possible to obtain an equation for the surface of that points?

thanks for help, I'm asking here because I didn't find a manual and I am not able to see the tutorial from the site (bad browser plugin)

Sorry for the late reply, I log into the bb from multiple machines and sometimes I don't notice the highlight the only time it shows up.

I found this when I looked for unread posts

I added a response to the sample directory - http://www.visualdatatools.com/SampleScripts/

The simplest way to do define this is to save the mesh in an array. In your case this would be a file with four numbers in each line and 6 lines. Start with the line where y = 1.4 and end with the line where y=2.4. This is also included in the tar file.

Actually, I'm trying to figure this out as well and I came across this discussion. I'm not seeing this example in the SampleScripts directory and that link gives me a 404. Wondering if I could get a copy of the example?

Thanks!

Sorry for that oversight. I must have put it into a different directory.

But it is there now. If that is not what you are looking for, let me know.
