[2005-09-15 15:14 UTC] james dot kilbride at gd-ais dot com

Description:
------------
The axis do not seem to be putting values in the correct locations on the axis, causing overlaps of values making the axis unreadable. This happens on both the X and Y axis. There are no errors in the log file.

Test script:
---------------
Change test file category.php near end to read:

...
* which they exist "before" in the dataset on their first occurence)
*/

$Plot =& $Plotarea->addNew('scatter', $DS);

$Marker =& Image_Graph::factory('Image_Graph_Marker_Cross');
$Marker->setFillColor('blue');
$Marker->setLineColor('black');
// set a line color
$Plot->setMarker($Marker);
$Graph->done();

Expected result:
----------------
I expect the axis to be well ordered without gaps and no overlapping.

Actual result:
--------------
Odd gaps are formed and there is overlapping displays of text which makes it unreadable and useless.

This is not purely a 1 plot issue. I can provide you with code that has dual plots(both scatters) which reproduces the issues. I'll put togethor a data set that does it. I have a suspicion it has something to do with the datasets themselves and how the axis are created from the data sets.

Change data set in category.php to:

$DS =& Image_Graph::factory('dataset');
$DS->addPoint('Apache', 'Open Source');
$DS->addPoint('BSD', 'Open Source');
$DS->addPoint('Linux', 'Open Source');
$DS->addPoint('Microsoft', 'Proprietary');
$DS->addPoint('Micro', 'Proprietary');
$DS->addPoint('Minisoft', 'Proprie');
$DS->addPoint('Millisoft', 'Prop');

$DS2 =& Image_Graph::factory('dataset');
$DS->addPoint('Apache', 'Open Source');
$DS->addPoint('BSD', 'Open Source');
$DS->addPoint('Linux', 'Open Source');
$DS->addPoint('Microsoft', 'Proprietary');
$DS->addPoint('Micro', 'Proprietary');
$DS->addPoint('Minisoft', 'Proprie');
$DS->addPoint('Miniority', 'Proprias');

And change plot code to:

$Plot =& $Plotarea->addNew('scatter', $DS);
//$Plot->setLineColor('red');

$Plot2 =& $Plotarea->addNew('scatter', $DS2);
//$Plot2->setLineColor('blue');
$Marker =& Image_Graph::factory('Image_Graph_Marker_Cross');

$Marker->setFillColor('blue');

$Marker->setLineColor('black');

// set a line color

$Plot->setMarker($Marker);
$Marker =& Image_Graph::factory('Image_Graph_Marker_Cross');

$Marker->setFillColor('red');

$Marker->setLineColor('black');

// set a line color

$Plot2->setMarker($Marker);
$Graph->done();

This duplicates the problem with 2 plots.
