How to force min max in the Y scale SCALE_MODE_MANUAL??
Hi there i trying to draw a chart using the SCALE_MODE_MANUAL with min=-66 and max=66
but the image is showing a scale of -80 to 80
I'm missing something THANKS.
Here the code
<?php /* CAT:Line chart */
/* pChart library inclusions */ include("./pChart2.1.3/class/pData.class.php"); include("./pChart2.1.3/class/pDraw.class.php"); include("./pChart2.1.3/class/pImage.class.php");
/* Create and populate the pData object */ $MyData = new pData(); $MyData->addPoints(array(-4,5,10,12,8,3),"Probe 1"); $MyData->addPoints(array(3,12,15,8,5,-5),"Probe 2"); $MyData->addPoints(array(2,7,5,18,19,22),"Probe 3"); $MyData->setSerieTicks("Probe 2",4); $MyData->setSerieWeight("Probe 3",2); $MyData->setAxisName(0,"Temperatures"); $MyData->addPoints(array("jan", "feb", "mar", "Apr", "May", "Jun"), "Labels"); $MyData->setSerieDescription("Labels","Months"); $MyData->setAbscissa("Labels");
/* Create the pChart object */ $myPicture = new pImage(700,230,$MyData);
/* Draw the background */ $Settings = array("R"=>170, "G"=>183, "B"=>87, "Dash"=>1, "DashR"=>190, "DashG"=>203, "DashB"=>107); $myPicture->drawFilledRectangle(0,0,700,230,$Settings);
/* Overlay with a gradient */ $Settings = array("StartR"=>219, "StartG"=>231, "StartB"=>139, "EndR"=>1, "EndG"=>138, "EndB"=>68, "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(0,0,699,229,array("R"=>0,"G"=>0,"B"=>0)); /* Write the picture title */ $myPicture->setFontProperties(array("FontName"=>"./pChart2.1.3/fonts/Silkscreen.ttf","FontSize"=>6)); $myPicture->drawText(10,13,"drawPlotChart() - draw a plot chart",array("R"=>255,"G"=>255,"B"=>255));
/* Write the chart title */ $myPicture->setFontProperties(array("FontName"=>"./pChart2.1.3/fonts/Forgotte.ttf","FontSize"=>11)); $myPicture->drawText(250,55,"Average temperature",array("FontSize"=>20,"Align"=>TEXT_ALIGN_BOTTOMMIDDLE));
$AxisBoundaries =array(0=>array("Min"=>-66,"Max"=>66));
$ScaleSettings = array("Mode"=>SCALE_MODE_MANUAL,"DrawSubTicks"=>TRUE,"Pos"=>SCALE_POS_TOPBOTTOM,"ManualScale"=>$AxisBoundaries); /* Draw the scale and the 2nd chart */ $myPicture->setGraphArea(500,60,670,190); $myPicture->drawFilledRectangle(500,60,670,190,array("R"=>255,"G"=>255,"B"=>255,"Surrounding"=>-200,"Alpha"=>10)); $myPicture->drawScale($ScaleSettings); $myPicture->setShadow(TRUE,array("X"=>-1,"Y"=>1,"R"=>0,"G"=>0,"B"=>0,"Alpha"=>10)); $myPicture->drawLineChart(); $myPicture->setShadow(FALSE);
/* Write the chart legend */ $myPicture->drawLegend(510,205,array("Style"=>LEGEND_NOBORDER,"Mode"=>LEGEND_HORIZONTAL));
/* Render the picture (choose the best way) */ $myPicture->autoOutput("pictures/example.drawLineChart.png"); ?>
