似乎 amCharts 默認(rèn)情況下為工具提示設(shè)置相同的顏色，即使設(shè)置了自定義工具提示 HTML：

// Create chart instance
var chart = am4core.create("chartdiv", am4charts.PieChart);
// Add data
chart.data = [{
? "country": "Lithuania",
? "litres": 501.9,
? "color": am4core.color("#ED1C24")
}, {
? "country": "Czechia",
? "litres": 301.9,
? "color": am4core.color("#235789")
}, {
? "country": "Ireland",
? "litres": 201.1,
? "color": am4core.color("#F1D302")
}, {
? "country": "Germany",
? "litres": 165.8,
? "color": am4core.color("#020100")
}];
// Add and configure Series
var pieSeries = chart.series.push(new am4charts.PieSeries());
pieSeries.dataFields.value = "litres";
pieSeries.dataFields.category = "country";
pieSeries.slices.template.propertyFields.fill = "color";
pieSeries.slices.template.tooltipHTML = "<p>My custom tooltip color:? {color}</p>"
chart.legend = new am4charts.Legend();
body {
? font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, Helvetica, Arial, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol";
}
#chartdiv {
? width: 100%;
? height: 400px;
}

<div id="chartdiv"></div>
（基于此 amCharts 演示的示例）
無論是使用自定義顏色還是通過刪除此行來使用主題顏色，這都適用：
pieSeries.slices.template.propertyFields.fill?=?"color";
因此，這個(gè)屬性可能在代碼中的其他地方被覆蓋。您可以通過添加此行來強(qiáng)制工具提示具有相同的填充顏色：
chart.tooltip.getFillFromObject?=?true;
編輯：顏色也可以通過工具提示 HTML 訪問"{color}"，以便它可以在樣式屬性中使用，例如。
