I find that candle function works well when the number of data is small, but once it is above 600, the function does not generate a proper candlestick chart. Anyone knows how to solve the problem?

Do you really expect to be able to visualize on a small scale 600 different points?
It seems like a lot to me and would not be visible on any regular sized piece of paper/ computer monitor etc.

I expect to use zoom to look closely and move forward

str = urlread('http://ichart.finance.yahoo.com/table.csv?s=GOOG&d=6&e=21&f=2011&g=d&a=7&b=19&c=2004&ignore=.csv');
[O,H,L,C] = dataread('string',str,'%*s%f%f%f%*f%*f%f','headerlines',1,'delimiter',',');
candle(H,L,C,O)
EDIT
with dates:
str = urlread('http://ichart.finance.yahoo.com/table.csv?s=GOOG&d=6&e=21&f=2011&g=d&a=7&b=19&c=2004&ignore=.csv');
[time,O,H,L,C] = dataread('string',str,'%s%f%f%f%*f%*f%f','headerlines',1,'delimiter',',');
candle(H,L,C,O,[],datenum(time,'yyyy-mm-dd'),'dd mmm yy')
Just zoom in.

Thanks for the code. Would it also work if I want to do a time series candlestick? (with time variable on the horizontal axis)
