As mentioned in the email, I would definitely add something like:<br>
my $i = 0;<br>
...<br>
if( $i++ > 5) {<br>
$ctx_table .=
"<tr><td>etc...</td></tr>";<br>
last;<br>
}<br>
<br>
I've had to analyse traces with hundreds of contexts in them before
now. Which would produce an HTML file swamped by a huge legend
(albeit with a beautifully smoothly shaded rainbow!).<br>
<br>
With that...<br>
