在 X 轴上的最后一列之后在 FusionChart 中渲染垂直线

Question

以下数组表示我的 Fusion Chart（条形图）的 X 轴元数据。如果日期是 today 即当前日期，我的要求是呈现一条垂直线。

例如：如果 today 是Wed 30-Aug-2011，我在数组中插入一个垂直线对象。这工作正常，一条线被适当地渲染。

但是，如果 today 是 Wed 31-Aug-2011，我在数组末尾插入 vline 对象。这一次，融合图表不呈现垂直线。

This page 表示可以在任意两个数据点之间放置垂直线。

我知道在这种情况下没有 两个 数据点（即vline 对象不在两个数据点之间）但是有没有办法仍然渲染线？ 我发现了一个 hack，它是在 vline 对象之后插入一个空白标签，但同样，它是一个 hack，它在右端创建了一个明显的空白区域。我们有合适的解决方案吗？或者这是我必须处理的限制？

黑客会是：

将vline定义放在最后一个类别之前，设置linePosition: 1如下图：

请确保您已设置canvasPadding 或隐藏画布边框以确保vline 不与画布边框重叠。
