嗨,我一直在努力制作我想要的图表,并且我正在变得非常接近。jpgraph双Y轴问题

首先,我有一个应该在YAXIS#1上的股票投资组合的业绩数据......这很好。 然后我想在YAXIS#2 ...行情节工作的标杆,但规模是怪异:

enter image description here

注意它是如何开始于50和10进,15,20,等等。 。 事情是规模应该在3400和3800之间,因为这是我的数据范围。

这里是我的代码:

<?php // content="text/plain; charset=utf-8" 
require($_SERVER['DOCUMENT_ROOT'] . '/wp-blog-header.php'); 
require_once ('jpgraph.php'); 
require_once ('jpgraph_line.php'); 
require_once ('jpgraph_date.php'); 
require_once ('jpgraph_utils.inc.php'); 

// Get a dataset 
$data = get_transient('daily_nav'); 
$ydata = $data[1]; 
$xdata = $data[0]; 

$data2 = get_transient('CAC40_history'); 
$ydata2 = array_reverse($data2[1]); 
$xdata2 = array_reverse($data2[0]); 


$dateUtils = new DateScaleUtils(); 
list($tickPositions, $minTickPositions) = DateScaleUtils::GetTicks($xdata); 

// Setup a basic graph 
$width=800; $height=500; 
$graph = new Graph($width, $height); 
$graph->SetScale('datlin'); 

$graph->SetYScale(0,'lin'); 
$graph->SetYScale(1,'lin'); 

$graph->SetMargin(60,20,40,60); 
$graph->xaxis->SetPos('min'); 
$graph->xaxis->SetTickPositions($tickPositions,$minTickPositions); 

// Setup the titles 
$graph->title->SetFont(FF_GEORGIA,FS_NORMAL,16); 
$graph->title->Set('Performance vs. CAC40'); 
$graph->subtitle->SetFont(FF_ARIAL,FS_ITALIC,10); 
$graph->subtitle->Set('graphique journalier depuis la création en juin 2012'); 

// Setup the labels to be correctly format on the X-axis 
$graph->xaxis->SetFont(FF_ARIAL,FS_NORMAL,8); 
$graph->xaxis->SetLabelAngle(30); 

// The second paramter set to 'true' will make the library interpret the 
// format string as a date format. We use a Month + Year format m-d-Y 
$graph->xaxis->SetLabelFormatString('m-Y',true); 


// And then add line. We use two plots in order to get a 
// more distinct border on the graph 
$lp2 = new LinePlot($ydata,$xdata); 
$lp2->SetColor('#71a7da'); 
$graph->Add($lp2); 
$graph->xgrid->Show(); 
$graph->AddY(0,$lp2); 

// second chart 
$lp3 = new LinePlot($ydata2, $xdata2); 
$lp3->SetColor('blue'); 
//$graph->Add($lp3); 
//$graph->xgrid->Show(); 
$graph->AddY(1,$lp3); 


// And send back to the client 
$graph->Stroke(); 
?> 

将是巨大的,如果有人能帮助,想不通这一个。 谢谢

我是一个新手,但一分钟前自己也有同样的问题。 缺少右边的零?尝试更改保证金设置?

$ graph-> SetMargin(60,50 ,40,60);
