  Line width of second line

Peter, I was unable to set the line width to 10 for the second line.
~~~
$c->addLineLayer($data0, 0xc00000)->setLineWidth(10);
$layer = $c->addLineLayer($data1, 0x00c000)->setUseYAxis2();
$layer->setLineWidth(10);
~~~
got the error:
Can't locate object method "setLineWidth" via package "LineLayer.setUseYAxis2" (perhaps
you forgot to load "LineLayer.setUseYAxis2"?) at foo3.pl line 47.

Thanks.

Hi Leo,

As according to ChartDirector documentation, the LineLayer object is returned from addLineLayer. It is not returned from setUseYAxis2. As according to ChartDirector documentation, the setUseYAxis2 does not return anything.

So the code should be:

#LineLayer object is returned by addLineLayer
$layer = $c->addLineLayer($data1, 0x00c000);

#setUseYAxis2 is a method of the LineLayer
$layer->setUseYAxis2();

#setLineWidth is a method of the LineLayer
$layer->setLineWidth(10);

Hope this can help.

Regards
