读到null这个点时会绘制为0
我想忽略null这个点跟99999.99这个点
以下是我的程式
<?php
include_once 'public.php';
//$mainFile = $ccuFile;
$mainFile = basename(__FILE__);//$yymFile;
extract(GetCCu($_GET['date']));
?>
<script>
$(document).ready(function(){
$('
#datetimepicker').datetimepicker({
dayOfWeekStart : 1,
lang:'ch',
timepicker:false,
format:'Y/m/d',
formatDate:'Y/m/d',
});
});
function querydata()
{
v = $('
#datetimepicker').val();
if (v.length <= 0)
return;
location.href = "<?php echo $mainFile; ?>?date="+v;
}
</script>
<script type="text/javascript"
src="
https://www.google.com/jsapi?autoload={
'modules':[{
'name':'visualization',
'version':'1',
'packages':['corechart']
}]
}"></script>
<script type="text/javascript">
google.setOnLoadCallback(drawChart);
function drawChart() {
var data2 = google.visualization.arrayToDataTable([ <?php echo $ccu2;
?>]);
var options2 = {
title: '<?php echo 'TW'; ?>',
curveType: 'function',
hAxis: {title: '<?php echo $ccu2_xtitle;
?>',format:'H'},
vAxis: {title: '<?php echo $ccu2_ytitle; ?>'},
legend: { position: 'right' },
};
var chart2 = new
google.visualization.LineChart(document.getElementById('chart2'));
chart2.draw(data2, options2);
}
</script>
<body>
<style>
body{
font-family:Microsoft JhengHei,Arial;
}
</style>
请选择查询日期 <input type="text" id="datetimepicker"
name="datetimepicker" value=""><input type="button" value="查询"
onclick="querydata()">
<div style="color: red"><?php echo $msg; ?></div>
<div style="font-size:20px;font-weight:bold;padding:0.5% 0 0 5% ;"><?php
echo $date; ?></div>
<div id="chart2"></div>
请问各位大大能教我怎麽改我的程式嘛?
