是否可以在系列/图后面显示形状？

Question

我正在尝试使用 ZingChart 重新创建以下内容：

到目前为止，除了标签标注提示和条形顶部之间的灰线之外，我拥有所有内容。我尝试使用形状创建线条，但无论设置 z-index，形状总是出现在条形顶部：

是否可以在图形后面放置形状？如果没有，我还有其他方法可以实现这个设计吗？

到目前为止我的 JSON：

Answer 1

ZingChart 导出功能制作的最终产品图像。只需右键单击图表并点击View As PNG

所以简短的回答是两件事：

1) 将zone 标签附加到scale-x，并将标尺移动到与placement:opposite 相对的一侧。

2) 在条形上方绘制折线图以获得灰线。

绘制线条的好处是您可以根据需要对线条应用动画。如果你想去掉动画，你也可以这样做。该图通常反应灵敏，希望此解决方案适合您的用例。

线条本身遵循一个简单的公式，将每个线条的值绘制为[barValue + 2, maxScaleYValue]。

这里唯一的问题是我设置了一个最大值scaleY。我这样做的原因是，这条线在整个调整大小时保持一致。如果您正在动态更新图表，这应该不是问题，因为您也可以更新最大 scaleY 值。只需对您的条形值数组进行排序，然后选择最高值 + 30。或者您自己的一些公式！

我对您的代码所做的重大更改是：

• 将标签挂在秤上
• 隐藏比例线并添加绘图区域边框
• 绘制数组数组[[]] 折线图
• 将条形图调整为单个系列并应用styles

var maxYValue = 70;
var value1 = 40;
var value2 = 15;
var value3 = 34;
var value4 = 14;
var value5 = 20;
