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

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 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
