 Alpha for a single Series in SteckedChartArea Hi JD, The Alpha value in the following array has no influence on result (pChart 2.1) $serieSettings = array("R"=>200,"G"=>200,"B"=>200,"Alpha"=>5); How to lower visibility of a series? Reimar Code: <?php
/* CAT:Misc */
/* pChart library inclusions */
include("pChart2/class/pData.class.php");
include("pChart2/class/pDraw.class.php");
include("pChart2/class/pImage.class.php");
/* Create and populate the pData object */
$MyData = new pData();
$MyData->addPoints(array(2,7,5,18,VOID,12,10,15,8,5,6,9),"Help Desk");
$MyData->addPoints(array(1,1,1,1,10,2,1,5,1,1,1,0),"Help Desk2");
$MyData->setAxisName(0,"Incidents");
$MyData->addPoints(array("Jan","Feb","Mar","Apr","May","Jun","Jui","Aou","Sep","Oct","Nov","Dec"),"Labels");
$MyData->setSerieDescription("Labels","Months");
$MyData->setAbscissa("Labels");
/* Create the pChart object */
$myPicture = new pImage(700,230,$MyData);
/* Do some cosmetics */
$myPicture->drawLine(60,0,60,230,array("R"=>70,"G"=>70,"B"=>70));
$myPicture->drawRectangle(0,0,699,229,array("R"=>0,"G"=>0,"B"=>0));
$myPicture->setFontProperties(array("FontName"=>"pChart2/fonts/Forgotte.ttf","FontSize"=>11));
$myPicture->drawText(35,115,"Recorded cases",array("R"=>255,"G"=>255,"B"=>255,"FontSize"=>20,"Angle"=>90,"Align"=>TEXT_ALIGN_BOTTOMMIDDLE));
/* Prepare the chart area */
$myPicture->setGraphArea(100,30,680,190);
$myPicture->setFontProperties(array("R"=>55,"G"=>55,"B"=>55,"FontName"=>"pChart2/fonts/verdana.ttf","FontSize"=>10));
$myPicture->drawScale(array("AxisR"=>55,"AxisG"=>55,"AxisB"=>55,"DrawSubTicks"=>TRUE,"CycleBackground"=>TRUE));
/* Write two thresholds over the chart */
/* Draw the chart */
$serieSettings = array("R"=>200,"G"=>200,"B"=>200,"Alpha"=>5); // Alpha doesn't seem to have any influence here
$MyData->setPalette("Help Desk",$serieSettings);
//$myPicture->drawStackedAreaChart(array("ForceTransparency"=>50));
$myPicture->drawStackedAreaChart();
$MyData->removeSerie("Help Desk");
$MyData->removeSerie("Help Desk2");
$MyData->addPoints(array(2,7,5,18,VOID,12,10,15,8,5,6,9),"Help Desk");
$MyData->addPoints(array(7,5,18,VOID,2,12,10,15,8,5,6,9),"Help Desk2");
$myPicture->drawSplineChart();
$myPicture->drawPlotChart();
/* Write the data bounds */
//$myPicture->writeBounds(); // Anzeige Min Max
/* Write the chart legend */
$myPicture->drawLegend(500,215,array("Style"=>LEGEND_NOBORDER,"Mode"=>LEGEND_HORIZONTAL));
/* Render the picture (choose the best way) */
$myPicture->autoOutput("pictures/example.drawThreshold.labels.png");
