Hey Christopher,

I don't know why that didn't work before, but it works now, so I got my graphs to work! Thank you so much! I finished them after we met with the client, so I didn't get to show them off, but we might mail them to anyways. Below are the two graphs. The graph on the left is from 2003, and the graph on the right is from a month ago.

Hey Robert,

I figured out how to convert my data to vector format, but now Maple says my data is not valid. I just can't get it to work. I also don't understand why nops(aa)=1. There are 47 vectors in aa. Robert, do you think you could send me the file where you plotted my data so I can take a look at it?

Now on to the issues I am having...

a:=ExcelTools:-Import........Foundation Survey 2.xlsx","3D data","B3:D49");

aa:=convert([seq(a[i],i=1..47)],vector)

 nops(aa);
                               1

tacc := Triangulate(aa, transparency = .5);
Error, (in Surfplot:-Triangulate) a Array is not valid rhs to < or <=

Surfdata_1.0.mw

I have also included my maple file. Any ideas what that last error means?

Thanks,

David

I really appreciate all of your help. I finally got Maple to load the surfplot package, but the triangulate statement is giving me trouble. Below is a sample of my data (except that the [] brackets are big and encompass all the data, not each row), and the error I am getting. I imported the data from three columns in excel. The pointplot3d worked just fine, but surfplot didn't like my triangulate statement.

> a[1 .. 2];
                     [22.5   26    0]
                     [28.0   26    0.25]

 tacc := Triangulate(a, transparency = .5);
Error, (in Surfplot:-Triangulate) only Vectors or 1D Arrays can be sorted

Another strange thing that is happening is below:

> nops(a);
                               4

On a different subject, should I be posting my file to MaplePrimes instead of just posting all this text?

Thanks!

David

Hello Robert,

I am so excited to see that somebody actually got this plotted. I loaded up the 8933.zip that you sent, and tried to follow the directions, but I got the same error that the other guys (Dirk, Jakubi, and Paul Weis) were having, except I have Maple 14, not 11.

Here is what happens in the first few steps... I tried to open up the links at the bottom of that post that you referenced, but the links were broken. Any suggestions?

Also, I am using a 64 bit Windows 7 system, that has already crashed the Excel add-on. Perhaps it has something to do with the fact that my "\" are disapearing when I define "Myname". Also, in Jakubi's original file, he defines it with slashes in the other dirction:

 Myname := `z:/entreprise/pwe/Maple/Delaunay`;
                z:/entreprise/pwe/Maple/Delaunay

Thanks,

David

Robert,

I looked at your attached link in detail this morning, and I didn't see any kind of "Surplot Package." I even searched the Maple 14 help file and google for both "surplot" and surfplot.

Could you more specifically reference the surplot package?

David

Above is the basic layout for my points. The outside of the rectangles are the outside of the house, and all the numbers are the approximate locations of the elevations. Is there any other way to to a 3D surface plot of this, or am I out of luck?

I don't think matrixplot will work, and a 3d point plot won't help me interpret what is going on very well.

Thanks,

David
