Ich versuche, ein Bild über die Bibliothek pChart 2.1.4 per Mail zu senden. Die Bibliothek wird in meinem Wordpress-Plugin verwendet.Render Bild mit pChart
Ich habe versucht, die folgenden:
/* Create and populate the pData object */
$MyData = new pData();
for($i=0;$i<=30;$i++) { $MyData->addPoints(rand(1,15),"Probe 1"); }
$MyData->setSerieTicks("Probe 2",4);
$MyData->setAxisName(0,"Temperatures");
/* Create the pChart object */
$myPicture = new pImage(700,230,$MyData);
/* Turn of Antialiasing */
$myPicture->Antialias = FALSE;
/* Add a border to the picture */
$myPicture->drawRectangle(0,0,699,229,array("R"=>0,"G"=>0,"B"=>0));
/* Define the chart area */
$myPicture->setGraphArea(60,40,650,200);
/* Draw the scale */
$scaleSettings = array("XMargin"=>10,"YMargin"=>10,"Floating"=>TRUE,"GridR"=>200,"GridG"=>200,"GridB"=>200, "DrawSubTicks"=>TRUE,"CycleBackground"=>TRUE);
$myPicture->drawScale($scaleSettings);
/* Write the chart legend */
$myPicture->drawLegend(600,20,array("Style"=>LEGEND_NOBORDER,"Mode"=>LEGEND_HORIZONTAL));
/* Turn on Antialiasing */
$myPicture->Antialias = TRUE;
/* Enable shadow computing */
$myPicture->setShadow(TRUE,array("X"=>1,"Y"=>1,"R"=>0,"G"=>0,"B"=>0,"Alpha"=>10));
/* Draw the area chart */
$Threshold = "";
$Threshold[] = array("Min"=>0,"Max"=>5,"R"=>207,"G"=>240,"B"=>20,"Alpha"=>70);
$Threshold[] = array("Min"=>5,"Max"=>10,"R"=>240,"G"=>232,"B"=>20,"Alpha"=>70);
$Threshold[] = array("Min"=>10,"Max"=>20,"R"=>240,"G"=>191,"B"=>20,"Alpha"=>70);
$myPicture->drawAreaChart(array("Threshold"=>$Threshold));
/* Render the picture (choose the best way) */
$today = date("Ymd");
$curr_user = wp_get_current_user();
$img_name = $today . $curr_user->user_login . ".png";
$myPicture->render($img_name);
