Hello,
Yes count=0 at the beginning initialises properly all elements
to zero.

subscript out of range
Hi Herman,
Thanks for your help. Just for discussion
purpose, isn't count=0 at the beginning of my code should have initialise all
count array to 0 (zero) ?
The problem is solved after I changed the
for(j=1;j<500;j++) to for(j=1;j<barcount;j++). The key is using
barcount, although I'm still not really understand the rationale behind but it
is working now.
Graham, thanks to you too. That is another way to
do it but a bit slow.
best regards
KK

<FONT face=Arial
color=#0000ff>If you use the subscript <FONT
color=#000000>Count[j]++; you are filling the array starting at
position zero, up to Count[500] in your case. All bars beyond index 500 will
contain a NULL (-1e10) and this is an unacceptable values for an array
subscript. I am not sure what you are trying to do, but the following
code would ensure that your subscript stays in a valid
range:
<FONT
face=Arial>Count=0<FONT
size=2>; j=<FONT
color=#ff00ff>1<FONT
color=#000000>; for<FONT
color=#000000>(j=1;
j<BarCount<FONT

if<FONT
color=#000000>(j<<FONT
color=#ff00ff>500<FONT
color=#000000>) Count[j]++; <FONT
color=#ff0000>else Count[j]=<FONT
color=#ff00ff>0<FONT
color=#000000>; } <FONT

<FONT face=Arial

is this:

range
Hi TJ,
The following is just a simple for loop. What
I do not understand is I'll get the subscript out of range error when
there is about a year data show on screen. When I use the zoom out button
so that the screen will show more data (may be 6 years), then the
subscript out of range error not happening. TJ, would appreciate your
clarification.
Tks
