javascript - 填充 amCharts 线条路径并删除 yAxes 值

Question

我使用 amCharts 来创建这个:

我遇到以下问题:

1. 我无法让 y 轴标签消失。看完documentation ，我尝试过 theYAxis.disabled = true;
2. 我希望折线图下方的所有内容都填充为蓝色。目前，我的只显示一条线。我尝试过:

var range = xAxis.axisRanges.create();
range.theXAxis.fill = chart.colors.getIndex(8);
range.theXAxis.fillOpacity = 0.2;

我哪里出错了？

演示:

var chart = am4core.create("dataChart", am4charts.XYChart);

chart.data = [{
    "xValue": "Q1",
    "yValue": 3
}, {
    "xValue": "Q2",
    "yValue": 4
}, {
    "xValue": "Q3",
    "yValue": 7
}, {
    "xValue": "Q4",
    "yValue": 2
}, {
    "xValue": "Q5",
    "yValue": 9
}];

/* Create axes */
var theXAxis = chart.xAxes.push(new am4charts.CategoryAxis());
theXAxis.dataFields.category = "xValue";

// tryin to get line to fill below
//var range = xAxis.axisRanges.create();
//range.theXAxis.fill = chart.colors.getIndex(8);
//range.theXAxis.fillOpacity = 0.2;

/* Create value axis */
var theYAxis = chart.yAxes.push(new am4charts.ValueAxis());
//theYAxis.disabled = true; // . trying to disable . to 1-10 showing here


/* Create series */
var series1 = chart.series.push(new am4charts.LineSeries());
series1.dataFields.valueY = "yValue";
series1.dataFields.categoryX = "xValue";
series1.bullets.push(new am4charts.CircleBullet());
series1.tooltipText = "{valueY} / 10";

/* Create a cursor */
chart.cursor = new am4charts.XYCursor();

#dataChart{
  width: 100%;
  height: 500px;
}

为了删除标签，您必须直接在轴渲染器上禁用标签，如 documentation 中所述。

theYAxis.renderer.labels.template.disabled = true;

如果您只需要在线下方进行基本填充，请直接在系列上设置fill和fillOpacity。

series.stroke = "#000088"; //for the line
series.fill = "#000088";  // for the fill
series.fillOpacity = .3;

var chart = am4core.create("dataChart", am4charts.XYChart);

chart.data = [{
    "xValue": "Q1",
    "yValue": 3
}, {
    "xValue": "Q2",
    "yValue": 4
}, {
    "xValue": "Q3",
    "yValue": 7
}, {
    "xValue": "Q4",
    "yValue": 2
}, {
    "xValue": "Q5",
    "yValue": 9
}];

/* Create axes */
var theXAxis = chart.xAxes.push(new am4charts.CategoryAxis());
theXAxis.dataFields.category = "xValue";

// tryin to get line to fill below
//var range = xAxis.axisRanges.create();
//range.theXAxis.fill = chart.colors.getIndex(8);
//range.theXAxis.fillOpacity = 0.2;

/* Create value axis */
var theYAxis = chart.yAxes.push(new am4charts.ValueAxis());
//theYAxis.disabled = true; // . trying to disable . to 1-10 showing here
theYAxis.renderer.labels.template.disabled = true;

/* Create series */
var series1 = chart.series.push(new am4charts.LineSeries());
series1.dataFields.valueY = "yValue";
series1.dataFields.categoryX = "xValue";
series1.bullets.push(new am4charts.CircleBullet());
series1.tooltipText = "{valueY} / 10";
series1.fill = "#000088";
series1.fillOpacity = .3;
series1.stroke = "#000088";

/* Create a cursor */
chart.cursor = new am4charts.XYCursor();

#dataChart{
  width: 100%;
  height: 500px;
}
