Post subject: | Combo Chart is not working |
Hi, i'm using pChart2.1.3 and have to draw a combo charts. I tried this example code from the website: Code: /* pChart library inclusions */ include("/usr/local/lib/pChart/class/pData.class.php"); include("/usr/local/lib/pChart/class/pDraw.class.php"); include("/usr/local/lib/pChart/class/pImage.class.php"); /* Create the pData object with some random values*/ $MyData = new pData(); $MyData->addPoints(array(30,24,32),"This year"); $MyData->addPoints(array(28,20,27),"Last year"); $MyData->addPoints(array("Year","Month","Day"),"Labels"); $MyData->setAbscissa("Labels"); /* Create the pChart object */ $myPicture = new pImage(700,230,$MyData); /* Create a solid background */ $Settings = array("R"=>179, "G"=>217, "B"=>91, "Dash"=>1, "DashR"=>199, "DashG"=>237, "DashB"=>111); $myPicture->drawFilledRectangle(0,0,700,230,$Settings); /* Do a gradient overlay */ $Settings = array("StartR"=>194, "StartG"=>231, "StartB"=>44, "EndR"=>43, "EndG"=>107, "EndB"=>58, "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"=>100)); /* Add a border to the picture */ $myPicture->drawRectangle(0,0,699,229,array("R"=>0,"G"=>0,"B"=>0)); /* Write the picture title */ $myPicture->setFontProperties(array("FontName"=>"/usr/local/lib/pChart/fonts/Silkscreen.ttf","FontSize"=>6)); $myPicture->drawText(10,13,"Chart title",array("R"=>255,"G"=>255,"B"=>255)); /* Draw the scale */ $myPicture->setFontProperties(array("FontName"=>"/usr/local/lib/pChart/fonts/Forgotte.ttf","FontSize"=>11)); $myPicture->setGraphArea(50,60,670,190); $myPicture->drawFilledRectangle(50,60,670,190,array("R"=>255,"G"=>255,"B"=>255,"Surrounding"=>-200,"Alpha"=>10)); $myPicture->drawScale(array("CycleBackground"=>TRUE)); /* Graph title */ $myPicture->setShadow(TRUE,array("X"=>1,"Y"=>1,"R"=>0,"G"=>0,"B"=>0,"Alpha"=>10)); $myPicture->drawText(50,52,"Chart subtitle",array("FontSize"=>20,"Align"=>TEXT_ALIGN_BOTTOMLEFT)); /* Draw the bar chart chart */ $myPicture->setFontProperties(array("FontName"=>"/usr/local/lib/pChart/fonts/pf_arma_five.ttf","FontSize"=>6)); $MyData->setSerieDrawable("Last year",FALSE); $myPicture->drawBarChart(); /* Draw the line and plot chart */ $MyData->setSerieDrawable("Last year",TRUE); $MyData->setSerieDrawable("This year",FALSE); $myPicture->drawSplineChart(); $myPicture->drawPlotChart(); /* Make sure all series are drawable before writing the scale */ $MyData->setSerieDrawable("This year",TRUE); /* Write the legend */ $myPicture->drawLegend(540,35,array("Style"=>LEGEND_ROUND,"Alpha"=>20,"Mode"=>LEGEND_HORIZONTAL)); /* Render the picture (choose the best way) */ $myPicture->render("diagramm.png"); echo "<img src=\"diagramm.png\">"; And as an result i got this chart: Attachment: diagramm.png [ 19.66 KiB | Viewed 10141 times ] As you can see i get two splines and two bars and not only one! I played a little around to find the bug and so i find out that the $MyData->setSerieDrawable(....) is not working - it's just ignored. Can anybody help me??? Thanks a lot Milly |

Having the same problem. setSerieDrawable() is not working for me also. However my series are independent, so I use removeSerie() instead |

Any ETA on any work on this problem? It works on the examples online, but not on the download. |
