Description: ------------ Odo graph timeouts when range is smallar than some magic value (in my example the magic value is 45). For example when range for the ODO graph is between 40 and 85 graph is generated successfully. When the range is between 40 and 84 the script timeouts (see bellow the error message). Run the test script and you will get an error like this: Fatal error: Maximum execution time of 30 seconds exceeded in /usr/share/pear/Image/Canvas/GD.php on line 865 (file name and line number changes) When I play with setAngles setting (e.g. $Plot->setAngles(135, 300)) the magic value when the script timeouts changes somehow. I checked this problem with ImageGraph version 0.7.2 (alpha) as well as with CVS version a few days old - with same results. Test script: --------------- <?php include 'Image/Graph.php'; $CURRENT = 50; $MIN_RANGE = 40; $MAX_RANGE = 84; // create the graph $driver=& Image_Canvas::factory('png',array('width'=>350, 'height'=>300, 'antialias' => 'native')); $Graph = & Image_Graph::factory('graph', $driver); $Graph->add($Plotarea = Image_Graph::factory('plotarea')); /***************************Arrows************************/ $Arrows = & Image_Graph::factory('dataset'); $Arrows->addPoint('Cur.', $CURRENT, 'current'); /**************************PARAMATERS for PLOT*******************/ $Plot =& $Plotarea->addNew('Image_Graph_Plot_Odo',$Arrows); $Plot->setRange($MIN_RANGE, $MAX_RANGE); /**************************RANGE*******************/ // create the dataset $Plot->addRangeMarker($MIN_RANGE, $MAX_RANGE); $Graph->done(); ?> Expected result: ---------------- Odo graph is drawn. When you change the range ($MAX_RANGE - $MIN_RANGE) >= 45 (e.g. $MAX_RANGE = 85;) everything works fine - ODO graph is drawn. Actual result: -------------- Fatal error: Maximum execution time of 30 seconds exceeded in /usr/share/pear/Image/Canvas/GD.php on line 865 (file name and line number changes)

I have made a change in 'Image/Graph/Plot/Odo.php' on line 382: - $step = (int) ($this->_totalY / $this->_deg_width * 6); + $step = ceil(($this->_totalY / $this->_deg_width * 6));
