Hi,


Working on this effort to use worksheet data to feed into a
three-dimensional cube graph.

I have an ODS worksheet with data formatted as numeric in three columns
with an x, y, and z header. I have read through the odsread function.

http://wiki.octave.org/IO_package#ODS_support

I understand I am loading the data into a memory variable called A.

I have looked at working examples of  three-dimensional cube graph.

I am unclear how to feed memory variable A to the syntax.


WORKING DIRECTORY:
>> ls -la *.ods
-rw-r--r-- 1 stephen stephen 10612 Jun 10 11:54 CubeGraphing.ods
-rw-r--r-- 1 stephen stephen 27218 Feb 18 11:30 Quadrant Graphing.ods
>>


FUNCTIONAL SYNTAX:
clf;
x = rand (20,1);  y = rand (20,1);  z = rand (20,1);
scatter3 (x(:), y(:), z(:), 20*z(:), z(:), 's');
title ({'scatter3() plot', ...
         'marker is square, size and color determined by Z'});



DEVELOPMENTAL SYNTAX:
clf;
A = odsread ('./CubeGraphing.ods', 'Data', 'C2:E5');

Try this:

x=A(:,1);

y=A(:,2);

z=A(:,3); 

scatter3 (x(:), y(:), z(:), [], z(:));

 

 [x, y, z] = peaks (20);
scatter3 (x(:), y(:), z(:), [], z(:));


How do I call memory variable A into the data array and list?

Am I correct I list with the scatter3 function?

Thank You,
