Description:
------------
Secondary axis ended up on right side of graph is value type axis was used (not category). Setting intersection point to 'max' does nothing to help this.
Bug is located in:
Axis::_intersectPoint($value)
if (($value === 'min') || ( $value < $this->_getMinimum() )) {
should be changed to
if (($value === 'min') || ( is_numeric($value) && $value < $this->_getMinimum() )) {
and
} elseif (($value === 'max') || ($value > $this->_getMaximum())) {
to
} elseif (($value === 'max') || (is_numeric($value) && $value > $this->_getMaximum())) {
Test script:
---------------
<?php
require_once 'Image/Graph.php';
$Graph =& Image_Graph::factory('graph', array(400, 300));
//$Plotarea =& $Graph->addNew('plotarea'); //Works correctly with categires
$Plotarea =& $Graph->addNew('plotarea',array('axis','axis'));
$Dataset1 = Image_Graph::factory('dataset');
$Dataset2 = Image_Graph::factory('dataset');
$i = 1;
while ($i <= 10) {
$Dataset1->addPoint($i, 10-$i);
$Dataset2->addPoint($i, $i*$i);
$i++;
}
$Plot1 =& $Plotarea->addNew('line', array(&$Dataset1));
$Plot2 =& $Plotarea->addNew('line', array(&$Dataset2),IMAGE_GRAPH_AXIS_Y_SECONDARY);
$AxisY =& $Plotarea->getAxis(IMAGE_GRAPH_AXIS_Y);
$AxisY =& $Plotarea->getAxis(IMAGE_GRAPH_AXIS_Y_SECONDARY);
$Graph->done();
?>
Expected result:
----------------
Plot displaying two graphs with one axis on right side and one on the left side.
Actual result:
--------------
The graph should have the secondary axis printed on the left side instead of the right side.
