Cannot read properties of undefined (reading 'myChart')

"Cannot read properties of undefined (reading 'myChart')"是一个错误提示，它表示在读取'myChart'属性时发生了undefined的错误。这个错误通常发生在myChart变量未定义或未正确初始化的情况下。

在你提供的代码中，我注意到在引用和引用中，myChart变量都被正确地定义和初始化为echarts.init(document.getElementById('main'))。因此，无法解释这个错误的原因。

可能的原因是，你在引用中提到了一个不同的问题，但没有提供相关的代码。如果你能提供更多的信息或相关代码，我将能够更好地理解问题并给出解决方案。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
