自定义锚点显示
图表的锚点和提示工具通常情况下是按默认效果显示的。隐藏锚点的折线图显示如下：
下表是用来显示锚点所需的属性：
drawAnchors-设置为1时显示锚点；设置为0时隐藏锚点。
上图所示图表隐藏锚点的数据结构如下：
JSON:
{
"chart": {
"caption": "Customer Satisfaction Averages",
"subcaption": "Last week",
"xaxisname": "Day",
"yaxisname": "Satisfaction (In %)",
"numbersuffix": "%",
"showvalues": "0",
"drawAnchors": "1",
"theme": "fint"
},
"data": [
{
"label": "Mon",
"value": "22.5"
},
{
"label": "Tue",
"value": "42.4"
},
{
"label": "Wed",
"value": "28.2"
},
{
"label": "Thu",

},
{
"label": "Fri",
"value": "39.2"
},
{
"label": "Sat",
"value": "66.45"
}
]
}
XML:
< set label="Mon" value="22.5" />
< set label="Tue" value="42.4" />
< set label="Wed" value="28.2" />
< set label="Thu" value="22.8" />
< set label="Fri" value="39.2" />
< set label="Sat" value="66.45" />
自定义锚点属性
自定义锚点属性的折线图效果如下：
下表是自定义锚点外观所需的属性：
anchorSides-用于指定锚点显示的边数，取决于你想显示什么形状的锚点，取值从3到20。
anchorRadius-用于指定锚点的直径。
anchorBorderColor-用于指定锚点边框显示的颜色，用十六进制代码。
anchorBorderThickness-用于指定锚点边框的厚度。 anchorBgColor 用于指定锚点的背景颜色，用十六进制代码。
anchorBgAlpha-用于设置锚点背景的透明度，取值从0到100。
上图所示自定义锚点的图表数据结构如下：

自定义指定数据点的锚点
FusionCharts允许用户通过自定义具体的锚点以突出显示特定的数据点。要突出显示特定的锚点，你只需要自定义锚点的外观。如下图所示：
使用数据对象的锚点自定义属性来对具体的数据点锚点进行配置。上图所示自定义指定数据点锚点使用的数据结构如下：
JSON:
{
"chart": {
"caption": "Customer Satisfaction Averages",
"subcaption": "Last week",
"xaxisname": "Day",
"yaxisname": "Satisfaction (In %)",
"numbersuffix": "%",
"showvalues": "0",
"anchorRadius": "6",
"anchorBorderThickness": "2",
"theme": "fint"
},
"data": [
{
"label": "Mon",
"value": "22.5",
"anchorBorderColor": "#cc3333",
"anchorBgColor": "#ff9900"
},
{
"label": "Tue",
"value": "42.4",
"anchorBorderColor": "#33cc00",
"anchorBgColor": "#66FF33"
},
{
"label": "Wed",
"value": "28.2",
"anchorBorderColor": "#cc3333",
"anchorBgColor": "#ff9900"
},
{
"label": "Thu",
"value": "22.8",
"anchorBorderColor": "#cc3333",
"anchorBgColor": "#ff9900"
},
{
"label": "Fri",
"value": "39.2",
"anchorBorderColor": "#33cc00",
"anchorBgColor": "#66FF33"
},
{
"label": "Sat",
"value": "66.45",
"anchorBorderColor": "#33cc00",
"anchorBgColor": "#66FF33"
}
]
}
XML:
< set label="Mon" value="22.5" anchorbordercolor="#cc3333" anchorbgcolor="#ff9900" />
< set label="Tue" value="42.4" anchorbordercolor="#33cc00" anchorbgcolor="#66FF33" />
< set label="Wed" value="28.2" anchorbordercolor="#cc3333" anchorbgcolor="#ff9900" />
< set label="Thu" value="22.8" anchorbordercolor="#cc3333" anchorbgcolor="#ff9900" />
< set label="Fri" value="39.2" anchorbordercolor="#33cc00" anchorbgcolor="#66FF33" />
< set label="Sat" value="66.45" anchorbordercolor="#33cc00" anchorbgcolor="#66FF33" />
在折线图和曲线图的锚点添加图片
折线图和面积图的锚点现在支持外部图像，允许你为每一个锚点使用不同的图像，突出显示某些特殊值。折线图锚点带有外部图像的效果图如下：
下表是用于配制锚点外部图像所需的属性：
anchorImageUrl-用于指定锚点所需图像的URL。
anchorImageAlpha-用于指定锚点图像的透明度，取值从0到100。
anchorImageScale-用于指定外部图像的加载比例。
anchorImageHoverScale-用于指定当鼠标悬停在锚点上，外部图像的加载比例。
anchorImageHoverAlpha-用于指定当鼠标悬停在锚点上，锚点图像的透明度，取值从0到100。
上图所示锚点添加外部图像用到的的数据结构如下：
