 defining the colors for lines |

I am trying to define my color for the line but getting error message as
$lineLayerObj = $chart->addLineLayer($ydata, -1, $legend);
$lineobj = $lineLayerObj->getLine();
$color = "0xFFFF00";
$lineobj->setColor($color);
I am getting following error message
Fatal error: Call to a member function setColor() on a non-object in C:\\xampp\\htdocs\\Sprint-IQ\\ProcData.php on line 462
The purpose is to define my own dark colors for the line and the symbols.
Thanks,
Subhash |

Hi Subhash,
According to the ChartDirector documentation, the getLine object only returns an "opaque" object. This means the object are not usable by the user code. The only thing one may do with the object is to pass it to XYChart.addInterLineLayer.
So the return value of getLine should be treated like a "handle" but not as a real object.
In your case, note that there is another issue. The color should be 0xFFFF00 (without quotes), not "0xFFFF00".
To set the color of a line, use:
$color = 0xFFFF00;
$lineLayerObj = $chart->addLineLayer($ydata, $color, $legend);
Hope this can help.
Regards
