配置垂直分割线的位置

你可以配置垂直分隔线的显示位置。垂直分隔线显示在Friday和Saturday数据点数据点之间的折线图如下图所示：

fusionchart垂直分隔线

下表是配置垂直分隔线显示位置所需的属性：

属性名称 描述
linePosition 用来指定垂直分隔线的相对位置，取值从0到1。如果垂直分隔线被绘制在两个数据点之间，那么第一个数据点就是0，第二个数据点就是1。默认情况下，取值为0.5时垂直分隔线显示在两个数据点之间。
vLine 设置为1时显示垂直分隔线；设置为0时隐藏垂直分隔线。

上图所示的配置垂直分隔线的数据结构如下：

JSON:

{
    "chart": {
        "theme": "fint",
        "caption": "Visitors to website",
        "subCaption": "Last week",

        "yAxisName": "Visits",
        "showValues": "0"
    },
    "data": [
