Read Results Using boxplot

hello,

I wrote a program using java that makes some calculations and then gives the result in a text file, I need to read this results using the available methods in matlab.

The program runs as follows:

for example I have three loops, x, y , z and for each loop there will be 4 values which are the results, the form of the text is like this

example

x y z value1 value2 value3 value4

0 0 0 12 14 12 11

0 0 1 9 3 19 4

0 1 0 40 23 232 2

........

and so on, what i need is to plot a graph to get the smallest value in value1 and in value2... in terms of x,y,z

thanks
