Description: ------------ Isolated point in line graphs with breaks creates single vertex which is not used in polygon (polygons are drawn only when $numPoints > 1). If after that script starts to draw polygon based markers (triangle, circle, etc.) this single vertex is prepended to the first marker and additional line or filled area is drawn. This applies at least to GD Canvas. Test script: --------------- <?php require_once 'Image/Graph.php'; $Graph =& Image_Graph::factory('graph', array(400, 300)); $Font =& $Graph->addNew('font', 'Verdana'); $Font->setSize(10); $Graph->setFont($Font); $Graph->add( Image_Graph::vertical( Image_Graph::factory('title', array('Data \'Break\' Sample', 12)), Image_Graph::vertical( Image_Graph::vertical( $Plotarea1 = Image_Graph::factory('plotarea'), $Plotarea2 = Image_Graph::factory('plotarea'), 50 ), $Legend = Image_Graph::factory('legend'), 88 ), 5 ) ); $Legend->setPlotarea($Plotarea1); $Legend->setPlotarea($Plotarea2); $Dataset =& Image_Graph::factory('dataset'); $Dataset->addPoint('Jan', 10); $Dataset->addPoint('Feb', 12); $Dataset->addPoint('Mar', 3); $Dataset->addPoint('Apr', null); $Dataset->addPoint('May', 4); $Dataset->addPoint('Jun', 10); $Dataset->addPoint('Jul', null); $Dataset->addPoint('Aug', null); $Dataset->addPoint('Sep', 9); $Dataset->addPoint('Oct', 10); $Dataset->addPoint('Nov', null); $Dataset->addPoint('Dec', 14); $Marker1 =& Image_Graph::factory('Image_Graph_Marker_Circle'); $Plot1 =& $Plotarea1->addNew('line', array(&$Dataset)); $Plot1->setLineColor('red'); $Plot1->setMarker($Marker1); $Marker2 =& Image_Graph::factory('Image_Graph_Marker_Box'); $Plot2 =& $Plotarea2->addNew('line', array(&$Dataset)); $Plot2->setLineColor('red'); $Plot2->setMarker($Marker2); $Graph->done(); ?> Expected result: ---------------- Top graph shows error - additional line between first and last marker. Actual result: -------------- Lower graph shows good behaviour using another, not polygon based marker.
