好不容易抽出时间将Jqplot做下最后的总结，下面通过四个例子来学习Jqplot的一些常见技巧：
示例1. 设置线条颜色（包括背景色及线条颜色的批量赋值）

$(document).ready(function(){
var d1 = [[0, -10.3], [1, 7.0], [2, 15.7], [3, 0.5], [4, -10.4], [5, 1.1], [6, 13.2],[7, 1.8], [8, -4.5], [9, -1.8], [10, 2.0], [11, 3.0], [12, -3.5], [13, -7.4], [14, -11.3]];
var d2 = [[0, 1.3], [1, 12.8], [2, -8.2], [3, -5.2], [4, 16.4], [5, -5.3], [6, 8.1],[7, 15.1], [8, -4.4], [9, 7.8], [10, -1.4], [11, 0.2], [12, 1.3], [13, 11.7], [14, -9.7]]; var plot1 = $.jqplot('Chart1', [d1, d2], {
grid: {
drawBorder: false,
shadow: false,
//The background color of the whole chart.
background: '#FFFFFF'
},
highlighter: { show: true },
seriesDefaults: {
shadowAlpha: 0.1,
shadowDepth: 2,
fillToZero: true
},
series: [
{
color: 'red',
showMarker: true,
showLine: true,
markerOptions: {
style: 'filledCircle',
size: 8
},
rendererOptions: {
smooth: true
}
},
{
color: 'yellow',
showMarker: true,
showLine: true,
rendererOptions: {
smooth: true,
},
markerOptions: {
style: 'filledSquare',
size: 8
},
}
],
axes: {
xaxis: {
pad: 1.0,
tickOptions: {
showGridline: false
}
},
yaxis: {
pad: 1.05
}
}
});
});

示例2. 线条常见的属性控制及特点，本例中需要注意一下两点：
A. 本例定义了两种颜色，但共有三条线，所以颜色会轮流显示;
*有时鼠标放在节点上没有值显示或线条颜色显示黑色，有可能是加的颜色Chart无法识别；
B. series: [{ show: true }, { showLine: true, showLabel: false }]
此处需要注意的是如果需要精确控制每条线的显示，有几组数据，就要写几组属性控制列表.

示例4. Jqplot的实时显示效果：
关于Jqplot的实时显示效果，主要是通过setTimeout(JqplotEvent, 1000)来进行调用的，其他逻辑及显示与以上均保持一致。
