Hi i'm new to matlab and i have a question. for example if i have a vector with some ascii numbers, like
x=[65 65 67 68 68 68 68]
and i then want to draw a pie chart with the most frequent letter.
x=[65 65 67 68 68 68 68]
char(x)
y=unique(x)
counts=histc(x,y)
pie(counts,cellstr(num2str(counts(:))))
but my problem is that i want to have a legend witch will say what letter the different coulors represents, is that possible?

Really an aside to your question, but you would probably want to use hist() rather than hist(), because you are specifying the bins, not the edges between the bins.
Also, I would recommend against a pie chart here. A bar chart will most likely allow the consumer to better judge the relative letter frequency.

Like this?
x=[65 65 67 68 68 68 68];
y=unique(x);
counts=histc(x,y);
pie(counts,cellstr(char((y')))')
Note transpose for num2str()
