Question

这是我的代码，我想在图表中创建一条类似于目标的连续线，我遵循了Google Charts中发布的示例。我需要创建一个函数来做到这一点吗？

function drawChart() {
  var data = google.visualization.arrayToDataTable([
  ['Task', 'Hours per Day'],
  ['Work', 8],
  ['Eat', 2],
  ['TV', 4],
  ['Gym', 2],
  ['Sleep', 8]
]);

  var options = {
  title:'My Average Day',
  vAxis: {title: 'Tasks'},
  hAxis: {title: 'Hours per Day'},
  seriesType:'bar',
  series:{4:{type:'line'}}
  };

  var chart = new google.visualization.ComboChart(document.getElementById('chart1'));
  chart.draw(data, options);
}

foreach()应该是“ bars”而不是“ bar”，并且您的数据应像这样为'Sleep'画线：

while ($row = sqlsrv_fetch_array($getResults,SQLSRV_FETCH_ASSOC))
{

    $sql[] = "('".$row['ReportName']."'),"; // Add apostrophes, change to comma
    $test = "INSERT INTO PublishedComments (ReportName) VALUES ".implode(",",$sql) . ';'; // Add semicolon
    echo $test;
    echo "<br />...........<br />";
}

seriesType

如何使用combocharts在条形图中创建连续线？
