Hi everybody,
Im a newbie, but i hope someone can help me in this work...
Ill try to explain what i need to do in the best way, but my english is
not good...
Iv imported a big table of data, this table is something like this:
255 0 255 0 255 255 255 0 255 0
255 255 255 255 0 255 255 0 255 0
255 255 255 255 255 255 255 0 255 0
255 255 255 255 0 255 255 0 255 0
255 255 0 255 255 255 255 0 255 0
255 255 255 0 255 0 0 255 0 255
I need to calculate for every row the number of cells with "255" and the
number of cells with "0"... from this values i would like to obtain the
percentage of 0 presents in the row.... after i want to plot the data in
a graph showing the variations of this percentage along the rows...
What i want to obtain is an array of this type:
40
30
20
30
30
40
Someone can give me a hint on how to obtain this?? maybe anybody can
suggest me the functions i could use...
what software do you suggest me for plot the data?? i was thinking in
gnuplot.... so i can plot the graph in svg format...
Please help me
thank you
