Rajeesh,

 

It's not so easy. The problem is deciding which line to follow. SAR has clear rules on whether to be long or short. You method has no such rules. In your picture the first occurrence seems easy to follow. The subsequent occurrences have multiple choices as to which to follow. It would seem you would stay with the longer line, but there is no way to know this BEFORE the line is drawn. See your screen shot attached with notes.

 

If you can make some "rules" as to which line to follow without any conflicts, it can be coded.

Hi Terry,

 

Thanks once again for the effort....

 

I am attaching a graph. The upper frame shows your

plotted line.

 

The below frame shows the example of the line the way

I am requesting it.(it shows SAR as line..which needs

to be converted to plot HHV/LLV).

 

Hope I am clear now....

 

Thanks and Regards,

 

Raajesh
