How to compute the standard deviation of a curve in hypergraph through tcl script.
How to compute the standard deviation of a curve in hypergraph through tcl script. Are there any other statistical parameters which can be computed using tcl script. If any sample scripts are available please support

Hello @ P S Partha Sai,
Please correct me if I'm wrong but you recently commented a script which extract some statistics
(Not standard deviation) and we provided you some guidance (in addition of the script faq) to complete the existing script.
Are you facing any issue adding the extra lines to adapt the script to your needs?
Best Regards,
Michael

Curve Name : {label}
Num Pts. : {min({numpts(x), numpts(y)})}
Length : {curvelength(x,y), %-10.3f}
Signed Area: {signedarea(x,y), %-10.4f}
Abs. Area : {absarea(x,y), %-10.3f}
X Y
------------- -------------
RMS {rms(x), % 1.6e} {rms(y), % 1.6e}
Min {min(x), % 1.6e} {min(y), % 1.6e}
Max {max(x), % 1.6e} {max(y), % 1.6e}
Median {median(x), % 1.6e} {median(y), % 1.6e}
Delta {delta(x), % 1.6e} {delta(y), % 1.6e}
Centroid {centroid(x,y)[0], % 1.6e} {centroid(x,y)[1], % 1.6e}
Mean {mean(x), % 1.6e} {mean(y), % 1.6e}
Variance {variance(x), % 1.6e} {variance(y), % 1.6e}
Skewness {skewness(x), % 1.6e} {skewness(y), % 1.6e}
Std. Dev. {sqrt(variance(x)), % 1.6e} {sqrt(variance(y)), % 1.6e}
Avg Dev. {avgdev(x), % 1.6e} {avgdev(y), % 1.6e}
Zero-Crossings {zerocrossings(x), % 1.6e} {zerocrossings(y), % 1.6e}
=============================================we can use templex eval in tcl script
$templexHandle Evaluate "{sqrt(variance(x))" true
hwi GetSessionHandle sess
sess GetProjectHandle p
p
% p GetTemplexHandle t
t
% t Evaluate "{sqrt(variance(p1w1c1.x))" true

Thank you very much, as this could give me fair idea on how to proceed further.

Hi Michael,
The comments by Mr Venkata Chittala, were useful and I could modify the script to compute the parameters which I need.
How ever I would request for one more help, to obtain the stats over the plot area. Are there any scripts for this. Thanks in advance.

hello @P S Partha Sai ,
that is great you were able to get the code for your statistics needs! For the note, did you hve a look at some scripts in community? At first glance the script below should help:
Did you already try it?

Michael
