amcharts如何改变y轴的文字

Question

我正在尝试将 Y 轴上显示的值更改为自定义文本，或在值旁边添加文本。我可以更改 valueAxis 文本吗？

这是代码

// Themes begin
am4core.useTheme(am4themes_animated);
// Themes end

// Create chart instance
var chart = am4core.create("chartdiv", am4charts.XYChart);

// Add data
chart.data = [{
  "year": "2008",
  "label": 101
}, {
  "year": "2009",
  "label": 142
}, {
  "year": "2010",
  "label": 462
}, {
  "year": "2011",
  "label": 364
}, {
  "year": "2012",
  "label": 465
}];

....

// Create value axis
var valueAxis = chart.yAxes.push(new am4charts.ValueAxis());
valueAxis.renderer.inversed = false;
valueAxis.title.text = "";
valueAxis.renderer.minLabelPosition = 0.001;

// Create series
var series1 = chart.series.push(new am4charts.LineSeries());
series1.dataFields.valueY = "label";
series1.dataFields.categoryX = "year";
series1.name = "Currency";
series1.strokeWidth = 3;
series1.bullets.push(new am4charts.CircleBullet());
series1.tooltipText = "{name} in {categoryX}: {valueY}";
series1.legendSettings.valueText = "{valueY}";
series1.visible  = false;

// Add chart cursor
chart.cursor = new am4charts.XYCursor();
chart.cursor.behavior = "zoomY";

// Add legend
chart.legend = new am4charts.Legend();

我要换200,300,400,500,600,700和800 到（例如）200s、300s、400s、500s、600s、700s、800s ..

Answer 1

一种快速的方法是使用 numberFormatter 并将 's' 添加到您的数字格式中，这将影响图表中的所有数值（轴、工具提示、图例值等）：

chart.numberFormatter.numberFormat = "#'s'";

在这种情况下，请务必在 s 周围加上引号以将其转义，因为它是绝对值的格式修饰符。

或者，如果您只是定位轴工具提示，请在 getTooltipText

上使用 adapter

valueAxis.adapter.add("getTooltipText", function(text, target, key) {
 return text + "s";
});
