🐛 [BUG]混合图表无法使用，codesandbox示例里面也无法渲染，点击进入'@antv/g2plot'里面也没有该方法

混合图表示例里面的引用，在npm包里面均未发现此方法，点击示例也无法渲染，如：ColumnLine、DualLine 、GroupedColumnLine 组件都无法找到

Start by comparing the mixed-chart examples and their CodeSandbox renders with the published @antv/g2plot npm package. Check whether ColumnLine, DualLine, and GroupedColumnLine are exported or referenced under different names. Done means the examples render successfully and every referenced component is available from the package.
