我在这里有一个折线图，出于某种原因，理想的线没有画出来。实际的线是画线，但理想的不是

echo "<script>";
echo "google.load(\"visualization\", \"1\", {packages:[\"corechart\"]});";
echo "google.setOnLoadCallback(drawChart);";
echo "function drawChart() { ";
echo "var data = google.visualization.arrayToDataTable([
['id ','Ideal', 'Actual'],";

$number = 0;
$numbers = 1;


echo "[0,$sum,$sum2],";

这是下面的代码，它打破了这条线（如果我有它说为空的值，它会画线）（但如果单词为空或在中没有值，它目前没有）

while($row = mysql_fetch_array($query))
{
$Ideal = $row['UserStoryPoints'];
$Actual = $row['WorkRemain'];
            echo "[$numbers, null ,$Actual],";
$numbers++;

}

'

echo "[$numbers,0,,],";

echo "]);";

echo "var options = {
    pointSize: 5,

  title: 'Burn down chart - $test',
     hAxis: {
         minValue: $numbers,
         format:'0',
         title: 'Each Day',      
    },
    vAxis: {
         format:'0',
         title: 'Number of hours',
    },
};";

echo "var chart = new google.visualization.LineChart(document.getElementById('chart_div'));";
echo "chart.draw(data, options);";
  echo "}
</script>";

抱歉，这个答案太简单了吗？

echo "[$numbers, $Ideal ,$Actual],";
