 PERL: I cannot access the array after using Surface Chart's xAxis->getTicks() |

I am using the Surface Chart Axis Type graph
I want to overlay bars at the bottom of the graph that are relative to the x Axis position.
I do not know how to use the GetDrawArea option.
I tried getting the min and max ticks but the values returned are 0 and 100 yet my autoscaled range is from 1,500,000 to 1,900,000.
So I tried using GetTicks and get nothing in return.
Here are a few of my setups of the graph.
my $c = new SurfaceChart(1060, 900);
$c->setData($dataX, undef, $dataZ);
$c->yAxis()->setLabels($dataY);
The graph looks great and comes out as intented.
Below is the GetTicks() I used (taken from another post)
$xlabels = $c->xAxis()->getTicks();
for($i=0; $i<=$#$xlabels; $i++){
$hr = $$xlabels[$i];
print STDERR "$hr\\n";
}
Any help would be greatly appreciated. |

Hi Paul,
As according to the ChartDirector documentation on Axis.getTicks, it should be called only after calling BaseChart.layout. Have you called BaseChart.layout first?
$c->layout();

It works PERFECTLY now after added $c->layout(); I missed that nuance.
