Angularjs 发布时间：2022-04-20 发布网站：大佬教程 code.js-code.com

大佬教程收集整理的这篇文章主要介绍了angularjs – ZingChart根据X-Scale更改绘图CSS，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

我正在使用ZingChart和AngularJs.

我有一个简单的图表,但我想我的情节是红色的,如果它是在过去(如果x尺度日期<当前日期). 我发现我可以设置一些规则

"plot":{
"rules":[
    {
        "rule":"%v  20 && %v < 30","line-color":"#f93","line-width":"8","line-style":"dashed"
    },]

如果情节值在20-30之间,哪个会改变css.我的问题是 – >
如何在X刻度值上更改绘图背景颜色依赖？我无法在情节属性上引用X-scale propery ..

您将寻找％scale-key-text标记,而不仅仅是％v. ％scale-key-text将以scale-x轴为目标.
