poptip 是 Ant Design Charts 中的一种交互类型,用于在用户与图表元素交互时显示简洁的提示信息。它提供了一种轻量级的方式来展示数据点的详细信息,而不会干扰用户对整体图表的浏览体验。与完整的 tooltip 相比,poptip 更加简洁,通常只显示最基本的信息。
要启用 poptip 交互,只需在图表配置中添加 interaction: 'poptip' 或使用 chart.interaction('poptip', true) 方法。
{// 其他配置...interaction: { poptip: true }}
或者使用方法调用的方式:
{"interaction": {"poptip": true}}
poptip 交互的配置可以在图表的 options 对象中的 interaction 属性下进行设置:
{// 其他图表配置...interaction: {poptip: {// poptip 配置项offsetX: 10,offsetY: 10,// tip 样式配置tipBackgroundColor: 'rgba(0, 0, 0, 0.75)',tipColor: '#fff',},}}
poptip 交互支持以下配置项:
| 属性 | 描述 | 类型 | 默认值 | 必选 |
|---|---|---|---|---|
| offsetX | 提示框相对于触发点的 X 方向偏移量 | number | 8 | |
| offsetY | 提示框相对于触发点的 Y 方向偏移量 | number | 8 |
poptip 的样式配置项需要以 tip 为前缀:
| 属性 | 描述 | 类型 | 默认值 | 必选 |
|---|---|---|---|---|
| tipBackgroundColor | 提示框背景色 | string | 'rgba(0,0,0,0.75)' | |
| tipColor | 文本颜色 | string | '#fff' | |
| tipWidth | 提示框宽度 | string | 'max-content' | |
| tipPadding | 提示框内边距 | string | '1px 4px' | |
| tipFontSize | 文本字体大小 | string | '12px' | |
| tipBorderRadius | 提示框圆角半径 | string | '2.5px' | |
| tipBoxShadow | 提示框阴影 | string | '0 3px 6px -4px rgba(0,0,0,0.12), 0 6px 16px 0 rgba(0,0,0,0.08), 0 9px 28px 8px rgba(0,0,0,0.05)' |
poptip 交互会触发以下事件:
| 事件名 | 描述 | 回调参数 |
|---|---|---|
| poptip:show | 当 poptip 显示时触发 | { data, target, x, y } |
| poptip:hide | 当 poptip 隐藏时触发 | { target } |
可以通过以下方式监听这些事件:
chart.on('poptip:show', (event) => {console.log('Poptip shown:', event.data);});chart.on('poptip:hide', (event) => {console.log('Poptip hidden');});
