My graphs are not showing up with all of their grid lines online. If I look at the hardcopy, all the grid lines are showing up. Two days ago, the grid lines were showing up online and on the hardcopy. Note that I have upgraded the pg folder since then from CVS.

Thanks -- rac

Here is the code:

#------------Define the graph-----------------------

$choose = random(0,2,1);

@colors = ("blue", "red", "green");

$rc = $colors[$choose]; #Pick a random color

$xmin = -6;

$ymin = -6;

$xmax = 6;

$ymax = 6;

$graph = init_graph_no_labels($xmin,$ymin,$xmax,$ymax,

'axes'=>[0,0],'grid'=>[$xmax-$xmin,$ymax-$ymin]);

$f_graph = FEQ("$f for x in $interval[$n] using color:$rc and weight:3");

add_functions( $graph,$f_graph );

$label = new Label($xmin+1,$ymax-.5, "y = h(x)",'black','center');

$graph->lb($label);

$i = 0; # Number the axes

do {

$xtick = $i + $xmin + 1;

$labelx[$i] = new Label($xtick,0, "$xtick",'black','center');

if ($xtick!=0) {$graph->lb($labelx[$i]);}

$i =$i+1;

} while ($i<($xmax-$xmin)-1);

$i = 0;

do {

$ytick = $i +$ymin + 1;

$labely[$i] = new Label(-.2,$ytick+.1, "$ytick",'black','center');

if ($ytick!=0) {$graph->lb($labely[$i]);}

$i =$i+1;

} while ($i<($ymax-$ymin)-1);
