Post Value area
Hello!

I'm creating a graphic of probability.
My problem is following. Probability can take on a value from 0 till 1. But value area is set automatically. So it includes negative values. I'd like to remove negative values from Y axis, but I can't find the way.

I would be grateful for any help. Thanks.

Try setting the scale value, for eg:
Code:
  $AxisBoundaries = array(0=>array("Min"=>0,"Max"=>100));
  $ScaleSettings  = array("Mode"=>SCALE_MODE_MANUAL,"ManualScale"=>$AxisBoundaries,"DrawSubTicks"=>TRUE,"DrawArrows"=>TRUE,"ArrowSize"=>6);
  $myPicture->drawScale($ScaleSettings);


You can also have a look at: http://wiki.pchart.net/doc.doc.draw.scale.html

With your help I managed to restrict the range of values on the graph.
