ECharts Cant get DOM width or height Please check domclientWidth and domclientHeight They should not be 0For example you may need to call this in the callback of windowonload

This error message indicates that ECharts is unable to retrieve the width and height of the DOM element that it is trying to render the chart into. To resolve this issue, you can follow these steps:

1. Make sure that you are calling echarts.init(dom) after the DOM element has been loaded. One common approach is to wrap the initialization code within the window.onload event callback function. For example:

   window.onload = function() {
     var dom = document.getElementById('chart-container');
     var myChart = echarts.init(dom);
     // rest of the chart initialization code
   }
   

2. Verify that the DOM element with the specified ID exists in your HTML. In the example above, there should be an element with the ID chart-container in your HTML.

3. Check if the DOM element has any CSS rules that may affect its rendering or dimensions. Make sure that there are no conflicting CSS properties like display: none, visibility: hidden, or height: 0, which can result in a zero width or height.

By ensuring that ECharts is initialized after the DOM element is loaded and that the DOM element has a valid width and height, you should be able to resolve this issue
