Subject: Plotting a graph out of different data sets that consist of numbers and labels

I am trying to plot a graph which makes sense to me, which is difficult to crunch in a single function, but let's say I want to see numeric data and labels as legends of this data to start with and then according to my professor I have to use different techniques to make the machine learn something new from the data, which is the tougher part.

The problem with my simplistic code is that I have no way of telling Octave that iris_data_1 and labels are just different columns of a single matrix that consists of different data types, so I had to tinker using a spreadsheet solution a process that I would have to automate later.

I was reading the cookbook at http://wiki.octave.org/Cookbook, and, I am no Jamie Olivier yet, unfortunately.

I ran:

addpath('...')

load('iris-data-1.dat')

load('iris-data-label.dat')

plot(...) //this is the part that is tough, because I do not know how to link the data so that the iris-data-label.dat file appears as a legend on the y axis.

plot(mean(íris-data) 

//this seems to work, I am not sure how to measure the accuracy though.
