我能够在React组件中绘制ZingChart图表，但不知道如何使用选择工具模块。
ZingChart网站上的文档(https://www.zingchart.com/docs/tutorials/features/selection)没有提到如何从React组件中实现。
我对React、ZingChart和前端开发的知识水平非常有限。
谢谢
因此，您需要做的是获取配置内容，并将其更改为所需模块的配置。如果你从zingchart react github页面的使用部分得到了一个组件，你的组件应该是这样的：
class App extends Component {
constructor(props) {
super(props);
this.state = {
config: {
type: 'bar',
series: [{
values: [4,5,3,4,5,3,5,4,11]
}]
}
}
}
render() {
return (
<div >
<ZingChart data={this.state.config}/>
</div>
);
}
}如果你查看你想要的模块的JavaScript部分，你会发现：
var myConfig = {
"graphset":[

};
zingchart.bind('myChart', 'click', function(e) {
if (e.target === "none") {
zingchart.exec('myChart', 'clearselection');
}
});
// Load the selection-tool and render the chart once its loaded
zingchart.loadModules('selection-tool', function() {
zingchart.render({
id : 'myChart',
data : myConfig,
height: '100%',
width: '100%',

});现在，您只需要获取配置并将其放入组件中，如下所示：

constructor(props) {
super(props);
this.state = {
