[Orca-users] Vertical marker in plots

[Tankersley, Jon]

I'd sent some 'hooks' for vrule into Orca directly to Blair.  The problem is the integration with the data streams.  Horizontal Rule was easy, and Blair adopted that.  VRules...are different.  They have to have EPOCH time stamps, etc.
 
I've put some thought into it... 
I don't know if we could figure out a way to have an RRD of just data for vrule lines and then have Orca generate a vrule for every data point in the rrdtool plot interval.  The problem comes in with dealing with annotation of the vrules.  I don't think RRD's can have 'non-numeric' entities associated with EPOCH time.
The other way would be to have some sort of 'include' file for the Orca run, but that didn't work all that well when I tried it.  I got inconsistent results.

	Hello, 
	
	I wanted to bring this topic up again to see if anyone has created a solution for this challenge.
	
	I also have the desire to insert Vertical Markers within the graphs for similiar reasons.  From my reasearch of the RDDtool interface, this can be acomplished using the function: 
	
	RDDs::graph option VRULE:time#color[:legend].  However, I am having difficulty getting a seperate Perl script to use that option with the Orca RRDs files.  I am curious is there a way to inject the VRULE option into the Orca plots by say sending the Orca script a signal to do such??  Or is a seperate script the way to go about doing this?   If the latter it the better way, will there be any way of accessing the Orca variable used in the Orca::ImageFile module? 
	
	Please forgive, I am new to Perl scripting as Orca has been my first endeavor in it.

	Hi orca-users, 
	
	I'm looking for a way of marking an event in time, by putting a vertical
	
	marker with a label in the plots, at a particular point in time. 
	
	This is to mark intor the plots when a change in the environment
	happend, so it is eaysy to correlate the effect of the change in
	performance (if any) , to time of the change.
