更改jpgraph的边距颜色

I am trying to change the color of the margin on a jpgraph. I cannot seem to figure it out. I tried $graph->SetMarginColor("khaki:0.6"); but that seemed to do nothing. below is the code that generates an example chart as well as the sample output. I am using jpgraph 3.5 if that helps.

$datay1 = array(20,15,23,15);
$datay2 = array(12,9,42,8);
$datay3 = array(5,17,32,24);

// Setup the graph
$graph = new Graph(300,250);
$graph->SetScale("textlin");

$theme_class=new UniversalTheme;

$graph->SetTheme($theme_class);
$graph->img->SetAntiAliasing(false);
$graph->title->Set('Filled Y-grid');
$graph->SetBox(false);

$graph->img->SetAntiAliasing();

$graph->yaxis->HideZeroLabel();
$graph->yaxis->HideLine(false);
$graph->yaxis->HideTicks(false,false);

$graph->xgrid->Show();
$graph->xgrid->SetLineStyle("solid");
$graph->xaxis->SetTickLabels(array('A','B','C','D'));
$graph->xgrid->SetColor('#E3E3E3');

// Create the first line
$p1 = new LinePlot($datay1);
$graph->Add($p1);
$p1->SetColor("#6495ED");
$p1->SetLegend('Line 1');

// Create the second line
$p2 = new LinePlot($datay2);
$graph->Add($p2);
$p2->SetColor("#B22222");
$p2->SetLegend('Line 2');

// Create the third line
$p3 = new LinePlot($datay3);
$graph->Add($p3);
$p3->SetColor("#FF1493");
$p3->SetLegend('Line 3');

$graph->legend->SetFrameWeight(1);

// Output line
$graph->Stroke();

?>

@RMcLeod我是jpgraph的新手,但据我所知,它输出一个图像,而不是html代码。
额外 作者 Richard,
之前没有用过jpgraph,但是你能不能找出图表的输出html是什么,然后用css改变页边距?
额外 作者 RMcLeod,
图像的边缘是否与D上的垂直线不一致?如果不是的话,我认为可以将空白视为背景,是否有改变这种情况的方法?
额外 作者 RMcLeod,

SetMarginColor is one of two commands you need. You also need to use SetFrame

$graph->SetTheme($theme_class);
$graph->img->SetAntiAliasing(false);
$graph->title->Set('Filled Y-grid');
$graph->SetMarginColor('khaki:0.6'); 
$graph->SetFrame(true,'khaki:0.6',1);   //The '1' here seems to be irrelevant
                                        //I've tried much larger numbers with no
                                        //change. This is supposed to be frame
                                        //width (in pixels). 
$graph->SetBox(false);

这会产生像这样的图像
