I'm Just Using the same ratio as the documentation
for $value1,$value2 and $area_plot
My Problem is that it generate the fine output to 3 loop but after 4 loop i don't know what happend the graph is upsidedown some are very small.I just want to know wat is the calculation in this dynamic graph
thanks
in Advance

Your range calculations are broken. I think $value1 is supposed to be the lower Y bound of each graph, and $value2 is the upper. But the way you increment them in the loop, $value1 passes $value2 and you end up with a negative area. Ouch. If it was me, I would do something like this at the bottom of the loop instead:
$value1 = $value2 + 20;
$value2 = $value1 + 300;
So each additional plot starts below where the previous one ends. Then you adjust the 20 and 300 to suit.

I have array of
$report[0]
..
..
$report[9]
$plot =& new PHPlot(800,2700);
$plot->SetImageBorderType('plain');
Disable auto-output:
$plot->SetPrintImage(0);
There is only one title: it is outside both plot areas.
$plot->SetTitle('Position Gender Graph');
$value1=40;
$value2=350;
$area_plot=117000;
for($i=0;$i<8;$i++){
$plot->SetPlotAreaPixels(80, $value1, 740,$value2);
$plot->SetDataType('text-data');
$plot->SetDataValues($report[$i]);
$plot->SetPlotAreaWorld(NULL, 0, NULL, $area_plot);
$plot->SetDataColors(array('blue'));
$plot->SetXTickLabelPos('none');
$plot->SetXTickPos('none');
$plot->SetYTickIncrement(1000);
$plot->SetYTitle("No of Employee");
$plot->SetPlotType('bars');
$plot->DrawGraph();
$value1+=500;
$value2+=400;
$area_plot-=11700;
}
Output the image now:
$plot->PrintImage();
