I had been created a SIMPLE LINE CHART, I had been use a Perl HoH and I had been use the references for got the data charts.
The HOH had been well created, I hab been verify using:
print Data::Dumper->Dump([%HoH]);
I had been print the axis X, Y:
print " AXISX: @$axisX
";
print " AXISY: @$axisY
";
AXIS X: "00:00","00:01","00:02","00:03","00:04","00:05","00:06","00:09","01:12","01:15",.....................,"12:53","12:59","13:02","13:20",........"23:56","23:57,"23:58","23:59",
AXIS Y:
-166.71,-175.43,-215.64,-208.62,402.50,401.00,401.00,402.01,400.50,-182,-174.00,.....................,-198.57,-243.74,402.1,403.99,........-271.12,-175.30,231.58,-179.19,
After and using Chartdirector, I han been create the XYChart
my $c= new XYChart(1000,640);
$c->setPlotArea(30,20,900,600);
$c->addLineLayer(@$ejeY)
##Set the labels on the X axis
$c->xAxis()->setLabels(@$ejeX);
##SHOW THE CHART
my $Chart1URL=$c->makeTmpFile("/tmp/tmpcharts");
my $imageMap= $c->getHTMLImageMap("","","title='{xLabel}:{value|0}%'");
.
..
.
print <<EndOfHTML
<img src="getchart.pl?img=/tmp/tmpcharts/$chart1URL" border="0" usemap"#map1">
<map name="map1"> $imageMap </map></center>
EndOfHTML
