Just an idea for an alternate way to go about it. Consider having Tk::Canvas only show a finite time period, say the last hour for example, Continue to save the data points in an array, and at program completion use Image::Magick or some similar graphics generating package generate a graph containing the full graph.
Not certain if it would work for your particular task, just figured I'd offer another potential way to attack the problem, and it might help solve the problem RobPayne mentioned of only a limited amount of space to draw in.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
