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.

Hmmm... this is weird. What seems to happen is that if you have _2_ plots it actually works, but if you have only 1 then it shows very wrong!

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.

This bug has been fixed in CVS.

If this was a documentation problem, the fix will appear on pear.php.net by the end of next Sunday (CET).

If this was a problem with the pear.php.net website, the change should be live shortly.

Otherwise, the fix will appear in the package's next release.

Thank you for the report and for helping us make PEAR better.
