ZingChart更改图CSS取决于X-Scale [英] ZingChart change plot CSS depending on X-Scale
问题描述
我在AngularJS中使用ZingChart.
I'm using a ZingChart with AngularJS.
我有一个简单的图表，但是如果过去是过去(如果x刻度日期<当前日期)，我希望绘图是红色的.
I have a simple chart, but I would like my plot to be red if it's in the past (if the x-scale date < current Date).
我发现我可以设置一些特定规则
I found out that I can set some certain rules to
"plot":{
"rules":[
{
"rule":"%v 20 && %v < 30",
"line-color":"#f93",
"line-width":"8",
"line-style":"dashed"
},
]
如果绘图值在20到30之间，将更改css.我的问题是-> 如何更改X比例值上的绘图背景颜色DEPENDING?我无法在绘图属性上引用x比例属性.
Which is going change css if the plot values are between 20-30. My question is -> How can I change plot background color DEPENDING on the X-scale value? I am not able to refernce x-scale propery on plot property..
推荐答案
您将在寻找％scale-key-text标记，而不是％v. ％scale-key-text将以scale-x轴为目标. http://www.zingchart.com/docs/basic-elements/zingchart-令牌/
You would be looking for the %scale-key-text token instead of simply the %v. %scale-key-text will target the scale-x axis. http://www.zingchart.com/docs/basic-elements/zingchart-tokens/
