タイトルにマウスオーバーすると、カスタムツールチップ（白い背景、黒いテキスト）が作成されました。
chart.renderer.textを使用し、グラフの中央に配置して、イベントの読み込み関数を作成します。ただし、「マウスオーバー」のタイトルの場合は、グラフ内のポイントのハイチャートツールチップと同様に、ツールチップをマウスに追従させたいと思います。
ハイチャートのタイトルはスパン要素であり、データポイントではないため、ツールチップのデフォルト関数を使用できません。ツールチップをタイトルスパン要素に配置するにはどうすればよいですか？フィドルを参照してください：

SVGRendererを使用してrect、textその内部で使用した場合と同じように、カスタムツールチップを作成できます。Highchartsを使用すると、SVG要素をグループに結合しshow()、hide()その上でSVGElementメソッドを使用できます。これにより、カスタムツールチップを切り替えることができます。また、ツールチップをマウスに追従させるために、このon()メソッドは、タイトル要素にイベントリスナーを追加し、translate()その位置を変更するのに役立ちます。以下に掲載されているコードとデモを確認してください。
コード：
chart: {
events: {
load: function() {
var chart = this,
title = chart.title,
titleBBox = title.getBBox(),
gTooltip = chart.renderer.g().add(),
textSvg,
textSvgBBox;
textSvg = chart.renderer
.text(
'Global mean Surface temperature anomalies with respect to 1970-2000' +
'<br>' + 'more text, more text more text more text',
titleBBox.x,
title.alignAttr.y + titleBBox.height
)
.css({
fill: '#fff'
})
.add(gTooltip);
textSvgBBox = textSvg.getBBox();
chart.renderer.rect(
titleBBox.x - 15,
title.alignAttr.y + titleBBox.height - 20,
textSvgBBox.width + 20,
textSvgBBox.height + 20
).attr({
fill: 'rgba(0, 0, 0, 0.8)',
stroke: 'black',
'stroke-width': 1
}).add(gTooltip);
textSvg.toFront();
gTooltip.hide();
title.on('mousemove', function(e) {
gTooltip.show().toFront();
gTooltip.translate(e.x - textSvgBBox.x, e.y - 10);
});
title.on('mouseleave', function(e) {
gTooltip.hide();
});
}
}
}
