我想用动态数据填充图表，但为了这样做，我想将pchart php文件嵌入到函数中，然后用
调用它echo "<img src='grafice();' /> ";
这可能吗？这就是我所做的：
function grafice()
{
/* pChart library inclusions */
include("../class/pData.class.php");
include("../class/pDraw.class.php");
include("../class/pImage.class.php");
/* Create and populate the pData object */
$MyData = new pData();
$MyData->addPoints(array(10,5,7,8), "Probe 1");
$MyData->setSerieWeight("Probe 1",2);
$MyData->setAxisName(0,"Media Generala");
$MyData->addPoints(array("Ian","Feb","Mar","Apr","Mai","Iun"),"Labels");
$MyData->setSerieDescription("Labels","Luni");
$MyData->setAbscissa("Labels");
$serieSettings = array("R"=>255,"G"=>185,"B"=>11);
$MyData->setPalette("Probe 1",$serieSettings);
/* Create the pChart object */
$myPicture = new pImage(500,230,$MyData);
/* Draw the background */
$Settings = array("R"=>248, "G"=>226, "B"=>174, "Dash"=>1, "DashR"=>190, "DashG"=>203, "DashB"=>107);
$myPicture->drawFilledRectangle(0,0,700,230,$Settings);
/* Overlay with a gradient */
$Settings = array("StartR"=>238, "StartG"=>216, "StartB"=>174, "EndR"=>238, "EndG"=>216, "EndB"=>174, "Alpha"=>50);
$myPicture->drawGradientArea(0,0,700,230,DIRECTION_VERTICAL,$Settings);
$myPicture->drawGradientArea(0,0,700,20,DIRECTION_VERTICAL,array("StartR"=>0,"StartG"=>0,"StartB"=>0,"EndR"=>50,"EndG"=>50,"EndB"=>50,"Alpha"=>80));
/* Add a border to the picture */
$myPicture->drawRectangle(0,0,499,229,array("R"=>0,"G"=>0,"B"=>0));
/* Write the picture title */
$myPicture->setFontProperties(array("FontName"=>"../fonts/Silkscreen.ttf","FontSize"=>6));
$myPicture->drawText(10,13,"Evolutia Mediei Generale",array("R"=>255,"G"=>255,"B"=>255));
/* Write the chart title */
$myPicture->setFontProperties(array("FontName"=>"../fonts/Forgotte.ttf","FontSize"=>11));
$myPicture->drawText(250,55,"Media Generala",array("FontSize"=>20,"Align"=>TEXT_ALIGN_BOTTOMMIDDLE));
/* Draw the scale and the 1st chart */
$AxisBoundaries = array(0=>array("Min"=>0,"Max"=>10));
$scaleSettings = array("DrawSubTicks"=>TRUE,"Mode"=>SCALE_MODE_MANUAL, "ManualScale"=>$AxisBoundaries);
$myPicture->setGraphArea(60,60,450,190);
$myPicture->drawFilledRectangle(60,60,450,190,array("R"=>0,"G"=>0,"B"=>0,"Surrounding"=>-200,"Alpha"=>10));
$myPicture->drawScale($scaleSettings);
$myPicture->setShadow(TRUE,array("X"=>1,"Y"=>1,"R"=>0,"G"=>0,"B"=>0,"Alpha"=>10));
$myPicture->setFontProperties(array("FontName"=>"../fonts/pf_arma_five.ttf","FontSize"=>10,"R"=>0,"G"=>0,"B"=>0));
$myPicture->drawLineChart(array("DisplayValues"=>TRUE,"DisplayR"=>0, "DisplayG"=>0, "DisplayB"=>0, "DisplayOffset"=>10));
$myPicture->setShadow(FALSE);
/* Render the picture (choose the best way) */
$myPicture->autoOutput("pictures/example.drawLineChart.png");
}
这甚至可能吗？如果没有，还有另一种方法吗？附：我只是想让函数使用预定义的点。我想我会设法为它添加动态数据。
答案 0 :(得分：0)
我设法做到了，并在这里张贴以帮助他人！
所以，我做了这个功能，但是我编辑了BOLD部分
function grafice()
{
/* pChart library inclusions */
include("../class/pData.class.php");
include("../class/pDraw.class.php");
include("../class/pImage.class.php");
/* Create and populate the pData object */
$MyData = new pData();
$MyData->addPoints(array(10,5,7,8), "Probe 1");
$MyData->setSerieWeight("Probe 1",2);
$MyData->setAxisName(0,"Media Generala");
$MyData->addPoints(array("Ian","Feb","Mar","Apr","Mai","Iun"),"Labels");
$MyData->setSerieDescription("Labels","Luni");
$MyData->setAbscissa("Labels");
$serieSettings = array("R"=>255,"G"=>185,"B"=>11);
$MyData->setPalette("Probe 1",$serieSettings);
/* Create the pChart object */
$myPicture = new pImage(500,230,$MyData);
/* Draw the background */
$Settings = array("R"=>248, "G"=>226, "B"=>174, "Dash"=>1, "DashR"=>190, "DashG"=>203, "DashB"=>107);
$myPicture->drawFilledRectangle(0,0,700,230,$Settings);
/* Overlay with a gradient */
$Settings = array("StartR"=>238, "StartG"=>216, "StartB"=>174, "EndR"=>238, "EndG"=>216, "EndB"=>174, "Alpha"=>50);
$myPicture->drawGradientArea(0,0,700,230,DIRECTION_VERTICAL,$Settings);
$myPicture->drawGradientArea(0,0,700,20,DIRECTION_VERTICAL,array("StartR"=>0,"StartG"=>0,"StartB"=>0,"EndR"=>50,"EndG"=>50,"EndB"=>50,"Alpha"=>80));
/* Add a border to the picture */
$myPicture->drawRectangle(0,0,499,229,array("R"=>0,"G"=>0,"B"=>0));
/* Write the picture title */
$myPicture->setFontProperties(array("FontName"=>"../fonts/Silkscreen.ttf","FontSize"=>6));
$myPicture->drawText(10,13,"Evolutia Mediei Generale",array("R"=>255,"G"=>255,"B"=>255));
/* Write the chart title */
$myPicture->setFontProperties(array("FontName"=>"../fonts/Forgotte.ttf","FontSize"=>11));
$myPicture->drawText(250,55,"Media Generala",array("FontSize"=>20,"Align"=>TEXT_ALIGN_BOTTOMMIDDLE));
/* Draw the scale and the 1st chart */
$AxisBoundaries = array(0=>array("Min"=>0,"Max"=>10));
$scaleSettings = array("DrawSubTicks"=>TRUE,"Mode"=>SCALE_MODE_MANUAL, "ManualScale"=>$AxisBoundaries);
$myPicture->setGraphArea(60,60,450,190);
$myPicture->drawFilledRectangle(60,60,450,190,array("R"=>0,"G"=>0,"B"=>0,"Surrounding"=>-200,"Alpha"=>10));
$myPicture->drawScale($scaleSettings);
$myPicture->setShadow(TRUE,array("X"=>1,"Y"=>1,"R"=>0,"G"=>0,"B"=>0,"Alpha"=>10));
$myPicture->setFontProperties(array("FontName"=>"../fonts/pf_arma_five.ttf","FontSize"=>10,"R"=>0,"G"=>0,"B"=>0));
$myPicture->drawLineChart(array("DisplayValues"=>TRUE,"DisplayR"=>0, "DisplayG"=>0, "DisplayB"=>0, "DisplayOffset"=>10));
$myPicture->setShadow(FALSE);
/* Render the picture (choose the best way) */
/* $myPicture->**( I DELETED ThIS)--> autoOutput <---** ("pictures/example.drawLineChart.png"); and added */
$myPicture->render("pictures/example.drawLineChart.png");
}
然后，当我想打电话时，就像这样：
<?php grafice(); ?>
然后我可以这样做：
<img src="pictures/example.drawLineChart.png" />
现在我只使用会话ID更改图片名称，因此我将为每个人提供不同的图表;）希望这会对某人有所帮助！
