  interlinelayer not working when x,y are swapped

I have created an interlinelayer color with two lines (y,x)

$Fdata, $xrisk

$Zdata, $xrisk

where $Fdata >= $Zdata

$F = $cRisk->addLineLayer($Fdata, $lineFolor3);
$F->setXData($xrisk);

$Z = $cRisk->addLineLayer($Zdata, $lineFolor3);
$Z->setXData($xrisk);

$Farea = $cRisk->addInterLineLayer($F->getLine(), $Z->getLine(), 0x5070DB70);

My problems occurs when I chart the lines with the y and x-axis swapped

$F1 = $cRisk->addLineLayer($xrisk, $lineFolor3);
$F1->setXData($Fdata);
$Z1 = $cRisk->addLineLayer($xrisk, $lineFolor3);
$Z1->setXData($Zdata);
$F1area = $cRisk->addInterLineLayer($F1->getLine(), $Z1->getLine(), 0x5070DB70);

I get no interlinelayer coloring
Any ideas ??

Hi John B,

There are infinitely many ways to fill between two lines. I have attached an image to show
two such possibilities - horizontal filling and vertically fill. To avoid ambiguity, the
InterLineLayer fills only along the y-axis direction, which is the most common method.

For your case, instead of swapping the x and y coordinates, please swap the x and y axes.
In this way, the y-axis is horizontal. As the InterLineLayer fills along the y-axis, it will fill
horizontally.

$F = $cRisk->addLineLayer($Fdata, $lineFolor3);
$F->setXData($xrisk);

$Z = $cRisk->addLineLayer($Zdata, $lineFolor3);
$Z->setXData($xrisk);

$Farea = $cRisk->addInterLineLayer($F->getLine(), $Z->getLine(), 0x5070DB70);

$cRisk->swapXY();

Hope this can help.

Regards
