[英]Trendline is not displaying in my chart
问题描述
I am using trendlines for my line chart. 
我在线图中使用趋势线。 But it is not visible in my browser.Can anyone tell me the reason for this. 但它在我的浏览器中不可见。任何人都可以告诉我这个的原因。 Below i am giving code: 下面我给出代码：
<?php
include("Includes/FusionCharts.php");
include("Includes/DBconn.php");
include("Includes/FC_Colors.php");
?>
<html>
<title> Blood Pressure</title>
<head>
<script language="javascript" src="FusionCharts/FusionChart.js"></script>
</head>
<body>
<center>
<?php
//connect to the DB
$link= connectToDB();
$query = "select * from patient_health order by ondate";
$result=mysql_query($query)or die(mysql_error());
//echo $result;
$strXML = "<graph caption='Blood Pressure Reading' subCaption='Month wise' xaxisname='Current Month' yaxisname='Blood Pressure(Systolic/diastole)' yAxisMaxValue='400'
animation='1' rotatenames='1'>";
$categories = "<categories>";
$systolic = "<dataset seriesName='systole'>";
$diaolic = "<dataset seriesName='diastole'>";
while ($row = mysql_fetch_array($result)) {
$categories .= "<category name='" . $row["ondate"] . "' />";
$systolic .= "<set color='AFD8F8' value='" . $row["systole_reading"] . "' hoverText='systolic' />";
$diaolic .= "<set value='" . $row["diastole_reading"] . "' color='FEDCBC' hoverText='diastolic'/>";
}
$strXML .= $categories . "</categories>" . $systolic . "</dataset>" . $diaolic . "</dataset>" . "</graph>";
**$strXML .=" <trendlines>
<line startValue='140' color='91C728' displayValue='Target' showOnTop='1'/>
</trendlines>";**
//$strXML now has the complete XML required to render the multi-series chart.
//Create the chart - Pie 3D Chart with data from $strXML
echo renderChartHTML("FusionCharts/FCF_MSLine.swf", "", $strXML, "BloodPressure", 850, 450,false);
//echo renderChartHTML("FusionCharts/FCF_MSBar2D.swf", "", $strXML, "BloodPressure", 850, 450,false);
?>
</center>
</body>

The code for the trend lines should come before you close the graph element, ie, before </graph> . 趋势线的代码应该在关闭图元素之前，即在</graph>之前。
As I've illustrated below: 正如我在下面说明的那样：
}
**$strXML .=" <trendlines>
<line startValue='140' color='91C728' displayValue='Target' showOnTop='1'/>
</trendlines>";**
$strXML .= $categories . "</categories>" . $systolic . "</dataset>" . $diaolic . "</dataset>" . "</graph>";
This should show your trend lines. 这应该显示您的趋势线。

It seems that in your code, you are closing the <graph> tag before adding <trendlines> ! 似乎在您的代码中，您在添加<trendlines>之前关闭了<graph>标记！
Correct code would be: 正确的代码是：
$strXML .= $categories . "</categories>" . $systolic . "</dataset>" . $diaolic . "</dataset>";
$strXML .=" <trendlines>
<line startValue='140' color='91C728' displayValue='Target' showOnTop='1'/>
</trendlines>" . "</graph>";
