我使用ZingChart和AngularJS。
我有一个简单的图表,但我希望我的情节在过去是红色的(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"
},
]
如果绘图值在20-30之间,那么将改变css。我的问题是 - &gt; 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。 http://www.zingchart.com/docs/basic-elements/zingchart-tokens/
var myConfig = {
"type": "line",
"title":{
"text":"%scale-key-value"
},
"subtitle":{
"text":"the parsed value"
},
"crosshair-x":{
"plot-label":{
"text":"%scale-key-value: $%v",
"decimals":2,
"transform":{
"type":"date",
"all":"%g:%i %A"
}
},
"scale-label":{
"visible":false
}
},
"plot":{
"tooltip":{
"visible":false
},
"rules": [
{
rule: "%scale-key-text > 1457116200000",
lineColor: "red"
}
]
},
"utc":true,
"timezone":-5,
"scale-x":{
"min-value":"1457101800000",
"max-value":"1457125200000",
"step":"30minute",
"transform":{
"type":"date",
"all":"%g:%i"
},
"label":{
"text":"Trading Day"
},
"item":{
"font-size":10
},
"max-items":14,
},
"scale-y":{
"values":"30:34:1",
"format":"$%v",
"label":{
"text":"Price"
},
"item":{
"font-size":10
}
},
"series": [
{
"values":[
