[Tioga-users] Restricting Line Plotting Domain/Range?

[Justin D. R. Steinfadt]

Hi all, I'm hoping there is an easy way to do this in Tioga that I'm 
just not seeing.

Here's the situation... I have two vectors of data defining the X and Y 
locations for points in my plot that define a function and say the 
domain runs from Xmin to Xmax in the X vector.  However, I only want to 
plot (using something like show_polyline) from Xbegin to Xend within my 
plot where Xbegin>Xmin and/or Xend<Xmax. (This also could be extended to 
the range of the data.)

I don't want to have to truncate my data to accommodate this and I would 
rather not have to look inside my data at all.

Is there perhaps some way to create a "Bounding Box" of sorts within the 
plot frame that restricts where a method like show_polyline might be 
able to draw a line?

Thanks for any help!
