Hi,
how can I create a frequency count or a histogram with LabTalk?
To my surprise, the LabTalk function:
histogram(dataset, inc, min, max)
is not working at al with my Origin v7.0273 on a WIN98 computer.
Is there any other LabTalk option for the creation of an histogram or a frequency count?
Thanks for any (urgently needed) help,
bye
Stefan

Hi Greg and Thomas,
thanks for your help.
Now the histogram function works also on my computer.
(There was a misunderstanding of the proper use of it and from my point of view the comment in origin-help should be improved.)
Thomas:
I did not know that trick before, thanks!
bye
Stefan

Hallo Stefan,
The easiest way is you copy the internal histogram function in Origin.
Open the script window, select a column in your worksheet, press
Strg and Shift and select in the Plot-menue under "statistical charts"
"histogram + probabilities".
Then the script shows up in your script window.
It basically should look like the following:
(I cannot test here at work because Origin7 (Pro) is still installed on my home PC)
i=200;// ergibt ca. 200 Klassen
limit -r sum.min sum.max i inc;
sum.min-=inc/2;sum.max+=inc/2;
w1=histogram(%C,inc,sum.min,sum.max);
win -T Data Count %CSHK;
col(2)=w1; del w1;
col(1)=data(sum.min+0.5*inc,sum.max+0.5*inc,inc);
col(3)=col(1);col(3)+=0,5*inc;
col(4)=sum(col(2));
set %H -e sum.n;
sum(col(4));
col(4)/=sum.max;
col(4)*=100;
Column 4 in the new worksheet "count" holds the cumulative percentage and column 1 the bins.
Hope this helps a bit.

Hi Stefan,
The histogram function works fine in v7.0552 (SR4) on my old Win98SE laptop. How does it fail for you?
