在Open Flash Chart 2中突出显示一个项目

Question

我该如何只需open flash chart 2中的一个项目（尤其是x轴上的一条线）就可以高亮显示？

注：突出显示可以是颜色或粗体的改变。

可以单独样式每个轴的标签，还有如何做到这一点的文档中的例子：

http://teethgrinder.co.uk/open-flash-chart-2/x-axis-labels-3.php

$x_labels = new x_axis_labels(); 

// Set the defaults 

$x_labels->set_steps(2); // show every other label 
$x_labels->set_vertical(); 
$x_labels->set_colour('#ff0000'); 
$x_labels->set_size(16); 

$tmp = array(); 

// these labels will inherit their properties from $x_labels 
// including 'visible' from the 'steps' value (which, for 
// this example is 2) I have noted the inherited visible 
// status for each item: 

$tmp[] = 'one';   // visible 
$tmp[] = 'two';   // invisible 
$tmp[] = 'three';  // visible 
$tmp[] = 'four';  // invisible 
$tmp[] = 'five';  // visible 

// these will override some or all of the 
// inherited properties 

$tmp[] = new x_axis_label('six', '#0000FF', 30, 270); // invisible 
$tmp[] = new x_axis_label('seven', '#0000FF', 30, 270); // visible 
$eight = new x_axis_label('eight', '#8C773E', 16, 315); // would be invisible, but: 
$eight->set_visible(); // <-- FORCE this label visible 
$tmp[] = $eight; 
$tmp[] = new x_axis_label('nine', '#2683CF', 16, 0); // visible 

// add the labels to the X Axis Labels object 
$x_labels->set_labels($tmp); 

A similar example for the Y-axis。
