Hi,

   I am trying to create the labels of red maker on every makers and how to i swap y
axis for set the zero value on the top please see at a picture. I would like to have a
suggestion.

this is my code.

require_once("/var/www/ChartDirector/lib/phpchartdir.php");

$barData = array(40);
$markData = array(12);
$markData2 = array(20);
$markData3 = array(33);
$markData4 = array(2);
$markData5 = array(19);
$markData6 = array(25);

$labels = array("Grp1");
$g1labels = array("SNP10-1");
$c = new XYChart(1024, 768);
$c->setBackground($c->linearGradientColor(0, 0, 0, $c->getHeight() / 2, 0xe8f0f8,
    0xaaccff), 0x88aaee);
$c->setRoundedFrame();
$c->setDropShadow();

$title = $c->addTitle("Chromosome with Markers", "ariali.ttf", 15);
$title->setMargin2(0, 0, 12, 12);

$c->setPlotArea(50, $title->getHeight(), $c->getWidth() - 65, $c->getHeight() -
    $title->getHeight() - 90, 0xe8f0f8, -1, Transparent, $c->dashLineColor(0x888888,
    DotLine));

$legendBox = $c->addLegend($c->getWidth() / 2, $c->getHeight() - 15, false,
    "arial.ttf", 8);
$legendBox->setAlignment(BottomCenter);

$legendBox->setBackground(0xe8f0f8, 0x445566);

$legendBox->setRoundedCorners(5);

$legendBox->setLineStyleKey();

$c->xAxis->setColors(Transparent);
$c->yAxis->setColors(Transparent);

$c->xAxis->setLabels($labels);

$markLayer = $c->addBoxWhiskerLayer(null, null, null, null, $markData, -1, 0xff0000);
$markLayer2 = $c->addBoxWhiskerLayer(null, null, null, null, $markData2, -1,
0xff0000);
$markLayer3 = $c->addBoxWhiskerLayer(null, null, null, null, $markData3, -1,
0xff0000);
$markLayer4 = $c->addBoxWhiskerLayer(null, null, null, null, $markData4, -1,
0xff0000);
$markLayer5 = $c->addBoxWhiskerLayer(null, null, null, null, $markData5, -1,
0xff0000);
$markLayer6 = $c->addBoxWhiskerLayer(null, null, null, null, $markData6, -1,
0xff0000);

$markLayer->setLineWidth(2);
$markLayer->setDataGap(0.1);
$markLayer2->setLineWidth(2);
$markLayer2->setDataGap(0.1);
$markLayer3->setLineWidth(2);
$markLayer3->setDataGap(0.1);
$markLayer4->setLineWidth(2);
$markLayer4->setDataGap(0.1);
$markLayer5->setLineWidth(2);
$markLayer5->setDataGap(0.1);
$markLayer6->setLineWidth(2);
$markLayer6->setDataGap(0.1);


$legendBox->addKey("Makers", 0xff0000, 2);

$barLayer = $c->addBarLayer($barData, 0x0066cc, "Chromosomes");

$barLayer->setBorderColor(Transparent, softLighting(Left));

$layoutLegendObj = $c->layoutLegend();
$c->packPlotArea(10, $title->getHeight(), $c->getWidth() - 15,
    $layoutLegendObj->getTopY() - 10);

header("Content-type: image/png");
print($c->makeChart2(PNG));


Thank you so much

Hi JuizyJ,

May be try:


$t = $markLayer->setDataLabelStyle("arialbd.ttf", 12, 0x000000);
$t->setAlignment(Right);
$t->setPos(0, -12);
$markLayer->setDataLabelFormat("Marker Name");


Hope this can help.

Regards
Peter Kwan

Hi JuizyJ,

You can use Axis.setReverse to have ChartDirector automatically reverse the axis:

$c->yAxis->setReverse();

If you want to configure the axis scale yourself, you should use a negative tick increment
for reversed axis, such as:

$c->yAxis->setLinearScale(60, 40, -2);

Hope this can help.
