log.js:61 [ECharts] There is a chart instance already initialized on the dom.解决

这个错误提示是因为在同一个 DOM 元素上已经存在一个 ECharts 实例，需要先销毁原来的实例再重新初始化。可以使用 `dispose()` 方法销毁实例，例如：

var myChart = echarts.init(document.getElementById('myChart'));
// ...
myChart.dispose(); // 销毁实例
myChart = echarts.init(document.getElementById('myChart')); // 重新初始化

[ECharts] There is a chart instance already initialized on the dom. 4 log.js:61

It seems like you are encountering an error with ECharts. The error message "There is a chart instance already initialized on the DOM" suggests that you are trying to initialize a chart on a DOM element that already has a chart instance associated with it.

To resolve this issue, you can either destroy the existing chart instance before initializing a new one or reuse the existing chart instance for your new data or configuration. Here's an example of how you can destroy a chart instance:

// Assuming chartInstance is the reference to your existing chart instance
chartInstance.dispose();```

After destroying the existing instance, you can initialize a new chart instance on the same DOM element without any conflicts.

Alternatively, if you want to reuse the existing chart instance, you can update its data or configuration using appropriate methods provided by the ECharts library.

Remember to make sure that you are not accidentally initializing multiple chart instances on the same DOM element.

这个错误提示是因为在同一个 DOM 元素上重复初始化了 echarts 实例。解决方法是先销毁已有的实例，再重新初始化。

可以使用以下代码销毁已有的实例：

var chartDom = document.getElementById('chart');
var chartInstance = echarts.getInstanceByDom(chartDom);
if (chartInstance) {
    chartInstance.dispose();
}

然后再重新初始化：

var myChart = echarts.init(chartDom);
