I was afraid my explanation would be vague. Lemme try to be more specific.

Suppose the following three alarms are in a log file:

Wed Feb 2 07:02:22 <vsm> 91041 Line 37 Severity 4 Vps 8
No Host Found - TN:2135572346

Wed Feb 2 07:02:22 <vsm> 91041 Line 23 Severity 4 Vps 3
No Host Found - TN:2156772216

Wed Feb 2 07:02:22 <vsm> 91041 Line 12 Severity 4 Vps 1
No Host Found - TN:2165523456

Now...let's suppose that the only one I really care about is the one in blue. What I want to do is prompt a user to tell me the "Line" number, then the "Vps" number. So for this example, the user would input Line 23 and Vps 3.

The script would then look at all 91041 alarms, find the one(s) for Line 23 and Vps 3, then report them back to me. As a bonus, it would also report the second line of the 91041 alarm to me, which is important because it has the TN. In other words, after running my script, one would see:

Wed Feb 2 07:02:22 <vsm> 91041 Line 23 Severity 4 Vps 3
No Host Found - TN:2156772216

Does that make more sense???

chart::clicker::renderer::line

Chart::Clicker::Renderer::Line(3pm)			User Contributed Perl Documentation		       Chart::Clicker::Renderer::Line(3pm)

NAME

       Chart::Clicker::Renderer::Line - Line renderer

VERSION

       version 2.83

SYNOPSIS

	 my $lr = Chart::Clicker::Renderer::Line->new(
	   brush => Graphics::Primitive::Brush->new({
	     #...
	   })
	 );

DESCRIPTION

       Chart::Clicker::Renderer::Line renders a dataset as lines.

ATTRIBUTES

   additive
       If true, the lines are drawn "stacked", each key accumulates based on those drawn below it.

   brush
       Set/Get a brush to be used for the lines.

   shape
       Set a shape object to draw at each of the data points.  Adding a shape results in:

   shape_brush
       Set/Get the brush to be used on the shapes at each point.  If no shape_brush is provided, then the shapes will be filled.  The brush allows
       you to draw a "halo" around each shape.	This sometimes help to separate the points from the lines and make them more distinct.

METHODS

   draw_point
       Called for each point encountered on the line.
