Question

我已經使用融合圖，我從數據庫中獲取值。我正在尋找如何在融合圖表php中爲折線圖設置趨勢值。其實我必須從數據庫中獲得價值並設置趨勢線。有沒有辦法做到這一點。我谷歌很多，但我沒有找到答案。

Here is my code: 

while ($row = mysql_fetch_array($result)) { 
    $categories .= "<category name='" . $row["ondate"] . "' />"; 
    $systolic .= "<set value='" . $row["systole_reading"] . "' hoverText='Systolic' />"; 
    $diaolic .= "<set value='" . $row["diastole_reading"] . "' hoverText='Diastolic'/>"; 
    $map.="<set value='" . $row["map"] . "' hoverText='Mean Arterial Pressure'/>"; 
    } 
$strXML .=" <trendlines> 
    <line startValue='".$row["target"]."' color='ff0000' displayValue='Systolic Target' showOnTop='1' valueOnRight = '1'/> 
    </trendlines>";

要爲PHP中的線圖TrendValues，你需要連接的XML字符串中的類似的方式，因爲你正在做的數據點。

Ref。代碼：

$strXML =" "; 
while ($row = mysql_fetch_array($result)) { 
$categories .= "<category name='" . $row["ondate"] . "' />"; 
$systolic .= "<set value='" . $row["systole_reading"] . "' hoverText='Systolic' />"; 
$diaolic .= "<set value='" . $row["diastole_reading"] . "' hoverText='Diastolic'/>"; 
$map .="<set value='" . $row["map"] . "' hoverText='Mean Arterial Pressure'/>"; 
$target .= "<line startValue='" . $row["target"] . "' color='ff0000' displayValue='Systolic Target' showOnTop='1' valueOnRight = '1'/>"; 
} 

$strXML .= "<chart><categories>" . $categories . "</categories><dataset>" . $systolic . "</dataset><dataset>" . $diaolic . "</dataset><trendLines>" . $target . "</trendLines></chart>";
