Charts GOOGLE折线图错误：给定轴上的所有系列必须具有相同的数据类型。空查询,charts,google-visualization,line,Charts,Google Visualization,Line,我对折线图有一个问题，当查询给出空结果或没有行时，折线图显示错误“给定轴上的所有系列必须具有相同的数据类型” 如果你仔细看有7个查询（每个人在同一个图表上画一条线），如果任何查询返回一个空结果（没有行），我会在主题标题中得到错误。当所有查询都不为空时，图表将正常工作有没有办法避免这个错误 <?php $curyear = date('Y'); $con = mysqli_connect('xxx','xxx','xxx','xxx'); ?> <html>

我对折线图有一个问题，当查询给出空结果或没有行时，折线图显示错误“给定轴上的所有系列必须具有相同的数据类型”

如果你仔细看有7个查询（每个人在同一个图表上画一条线），如果任何查询返回一个空结果（没有行），我会在主题标题中得到错误。当所有查询都不为空时，图表将正常工作

有没有办法避免这个错误
