Reported by wrsweeney
2012-08-09T19:05:13+00:00
PHP: 5.3.15 OS: Centos 5.8 Package Version: 0.8.0

Description:
------------
Customer needs stacked bar graph that displays proficiency of various agencies to solve problem. Attributes needed to calculate proficiency may be missing. In that case proficiency is calculated using average value. Then calculation is repeated using min value and max value. A line segment joining the min value calculation to the max value calculation is drawn on top of the average calculation in the stacked bar graph.

Expected result:
----------------
Expect to see the line segment drawn above the bar graph as it was in version 0.7.2 of Image_Graph.

Actual result:
--------------
Line segment is not visible. Enclosed in files attached see sample code that reproduces the bug in file RunAnalysis.php. Must change the filename in Graph->done statement and run from command line. Bad result image is in 123-factorReportGraph.png. Good result from 6-21-2011 is in

After upgrade from 0.7.2 to 0.8.0, showing a legend stops the script from working (it tries to require_once a class "white").

If I comment the usage of $Legend out, the graph is shown.
And it worked under 0.7.2 ... :(

Thanks for any help!

Test script:
---------------
// Does not work:
$Graph->add(Image_Graph::vertical(

Reported by marks
2010-11-13T21:25:53+00:00
PHP: 5.2.12 OS: Linux Package Version: 0.8.0

Description:
------------
May be its an intention not a bug, but having in DataPreprocessor_Array duplicate labels, they are displayed only for the first value, where used. Its caused by the if clause condition in Graph/Axis.php line 1181. I found this, because I intended to format Timestapms on x axis in 2 level, (first of the day in full format Y-m-d H:i others in the same day H:i only) and I have not succeed  to set up 2 levels of labels and so I decided to format my labels outside and deliver them through a DataPreprocessor_Array. as xvalue=>myformatedlabel. Setting upper mentioned condition to true gives expected results i my case, but I haven't studied the influence on other cases. Best regards Marek.

Description:
------------
I am using a stacked bar graph. If the graph has only one column, that column is given zero width.

Test script:
---------------
require_once('Image/Graph.php');
$Graph = & Image_Graph::factory('graph', array(500, 300));
$Graph->add(
  Image_Graph::vertical(Image_Graph::factory('title', rray('My way or the highway', 12)),

$Dataset1->addPoint('Jan', 1);
//$Dataset1->addPoint('Feb', 1); //comment this in and it works
$Dataset2 =& Image_Graph::factory('dataset');
$Dataset2->addPoint('Jan', 3);
//$Dataset2->addPoint('Feb', 3); //comment this in and it works
$Datasets = array($Dataset1,$Dataset2);
$Plot =& $Plotarea->addNew('bar', array($Datasets,'stacked'));
$Graph->done();


Expected result:
----------------
A single bar should have a minimum width.

Actual result:
--------------
A single bar is not visible, I assume that this is because it is zero width.

Image_Graph: Bug 16217 [Open] stacked bar graph doesn't work with one dataPoint

2009-05-11T15:45:48+00:00
PHP: 5.2.9 OS:  Package Version: 0.7.2

Description:
------------
A stacked bar graph simply isn't displayed if there is only a single data point (which multiple values).

(I discovered this while writing my test case for 16216)


Test script:
---------------
add( $plotarea = Image_Graph::factory('plotarea',array('category','axis','horizontal')) );
	
	$data = array( 1, 2, 1, 3 );
	for( $i=0; $i < count( $data); $i++ ) {
		$dataset[$i] = Image_Graph::factory('dataset'); 
		$dataset[$i]->addPoint( 'One', $data[$i] );
		//$dataset[$i]->addPoint( 'Two', $data[$i]*2 );
	}
			
	$plot = $plotarea->addNew('bar', array($dataset,'stacked')); 
	$plotarea->addNew('line_grid', array(), IMAGE_GRAPH_AXIS_Y);     
		
	$fillArray = @Image_Graph::factory('Image_Graph_Fill_Array');
	$fillArray->addColor( "blue@0.5" );
	$fillArray->addColor( "green@0.5" );
	$fillArray->addColor( "red@0.5" );
	$fillArray->addColor( "black@0.5" );
	$plot->setFillStyle($fillArray); 
	
	$xAxis = $plotarea->getAxis( IMAGE_GRAPH_AXIS_Y );
	$xAxis->forceMaximum( 9 );
	
	$graph->done();
?>

Expected result:
----------------
I'd expect the "One" dataset to be plotted.

Actual result:
--------------
Nothing is plotted.

Image_Graph: Bug 16216 [Open] forceMaximum on stacked bar graph "wraps" values

2009-05-11T15:40:32+00:00
PHP: 5.2.9 OS:  Package Version: 0.7.2

Description:
------------
On a stacked bar graph if you use forceMaximum and set a value "lower" than the total of one of the stacked graphs that last item seems to fill back to zero instead of that maximum.

Test script:
---------------
add( $plotarea = Image_Graph::factory('plotarea',array('category','axis','horizontal')) );
	
	$data = array( 1, 2, 1, 3 );
	for( $i=0; $i < count( $data); $i++ ) {
		$dataset[$i] = Image_Graph::factory('dataset'); 
		$dataset[$i]->addPoint( 'One', $data[$i] );
		$dataset[$i]->addPoint( 'Two', $data[$i]*2 );
	}
			
	$plot = $plotarea->addNew('bar', array($dataset,'stacked')); 
	$plotarea->addNew('line_grid', array(), IMAGE_GRAPH_AXIS_Y);     
		
	$fillArray = @Image_Graph::factory('Image_Graph_Fill_Array');
	$fillArray->addColor( "blue@0.5" );
	$fillArray->addColor( "green@0.5" );
	$fillArray->addColor( "red@0.5" );
	$fillArray->addColor( "black@0.5" );
	$plot->setFillStyle($fillArray); 
	
	$xAxis = $plotarea->getAxis( IMAGE_GRAPH_AXIS_Y );
	$xAxis->forceMaximum( 9 );
	
	$graph->done();
?>

Expected result:
----------------
I would expect the black bar on the top graph to extend to the right side.

Actual result:
--------------
Instead it goes to the left side -- the opacity has been set low so you can easily see the overlap of the colors.

The function "setRangeMarkerFillStyle" in Image_Graph_Plot_Odo has a return by "reference" but doesn't actually return anything.

This produces the "Only variable references should be returned by reference" error on PHP 5.

PHP: 5.2.6 OS: WIN32 Package Version: CVS

Description:
------------
in the list of values to be displayed on y axis, if ever there is a zero  (so basically a point on the x axis) one of the modules goes into an infinite loop trying to divide by zero (i'm guessing to scale the y axis to the values used )

Image_Graph: Bug 14551 [Open] forceMinimum screws up Axis span on logarithmic axis

chris dot stone at gmail dot com — 2008-08-23T03:18:20+00:00

Image_Graph Bug
Reported by xulchris
2008-08-23T03:18:20+00:00
PHP: 5.2.6 OS: Fedora 9 Package Version: 0.7.2

Description:
------------
When using forceMinimum and forceMaximum on a logarithmic axis, the axis span gets messed up.  For example, on auto it will plot an axis from 1 to 100 in the sample code below, but if you set a minimum of 20, then the maximum gets cut off by 20 as well and it plots from 20 to 80 instead of 20 to 100.

Test script:
---------------
addPoint($i,$i*$i);
$g = Image_Graph::factory('graph', array(1024, 768));
$g->add($p = Image_Graph::factory('plotarea', array('Image_Graph_Axis_Category', 'Image_Graph_Axis_Logarithmic')));
$p->addNew('line', $d);
$a = $p->getAxis(IMAGE_GRAPH_AXIS_Y);

// HERE IS THE BUG, THE GRAPH PLOTS FROM 20 to 100 instead of 20 to 120.
// IF WE REMOVE FORCE MAXIMUM OR SET IT TO 100, IT ONLY PLOTS TO 80.
$a->forceMinimum(20);
$a->forceMaximum(120);

$g->done(array('filename' => "foo.png"));

?>


Expected result:
----------------
setting forceMinimum should not affect the maximum in a log scale, for example:

$a->forceMinimum(20);
$a->forceMaximum(100);

this should plot from 20 to 100, not 20 to 80 as it currently does.

Actual result:
--------------
Messed up axis and plots.

PHP: 5.2.4 OS: Gentoo Linux Package Version: 0.7.2

Description:
------------
I created a line graph and enabled client side image maps. If I only assign one single data point to this line, no image map is created for this datapoint.

It seems like this is due to Image/Graph/Plot/Line.php Line 154 checks for "$numpoints > 1" and resets the line graph otherwise, which might be correct but omits rendering of the vertices if only one datapoint is in that line graph.

When setting $limit to any integer value greater than 0, $limit -Tags should be created.

Actual result:
--------------
When setting $limit to 1, no -Tag is created, setting it to anything greater than 1, -Tags are created accordingly.

Image_Graph: Bug 11897 [Assigned] Wrong color assignment in multi-dataset plots

Image_Graph Bug
Reported by sandermarechal
2007-08-23T13:41:44+00:00
PHP: 5.2.0 OS: Linux (Debian Etch) Package Version: 0.7.2

Description:
------------
For my graphs I have created a default set of colors to use simply by creating an Image_Graph_Fill_Array that everything uses. The amount of datasets in my plots usually changes (depending on the data) so I have created a standard bar graph that acts as a plot with multiple datasets. However, when only one dataset is actually present, every bar gets a different color instead of all the bars being the same color. It starts picking one color per datapoint instead of one color per dataset.

I think that it should always use one color per dataset if I create a plot with multiple datasets (e.g. 'stacked'), even though there is only one dataset it it.

Test script:
---------------
#!/usr/bin/php -q
 400, 'height' => 300, 'canvas' => 'svg')));
$graph->setBackgroundColor('white');
$graph->add($plotarea = Image_Graph::factory('plotarea'));

$color_array =& Image_Graph::factory('Image_Graph_Fill_Array');
$color_array->addColor('red');
$color_array->addColor('green');
$color_array->addColor('blue');

$dataset =& Image_Graph::factory('dataset');
$dataset->addPoint(0, 8);
$dataset->addPoint(1, 7);
$dataset->addPoint(2, 9);

// A 'multiple dataset' graph, but with one actual dataset. This makes all three bars a different color.
// If I would do instead: addNew('bar', array(array($dataset, $dataset), 'stacked'));
// then I would get a good plot with one color per dataset
$plot =& $plotarea->addNew('bar', array(array($dataset), 'stacked'));
$plot->setFillStyle($color_array);
$graph->done(array('filename' => 'test.svg'));

?>

Expected result:
----------------
One color per dataset -- even if there just happens to be only one dataset in the array of datasets.

Actual result:
--------------
Each bar of the dataset gets a different color.

Image_Graph: Bug 10161 [Verified] Different behaviour with bar graphs in 0.7.1 and 0.7.2

Image_Graph Bug
Reported by mj
2007-02-23T08:33:33+00:00
PHP: 5.2.0 OS: Linux Package Version: 0.8.0

Description:
------------
The reproducing script below generates a bar graph with a single bar in it.  With Image_Graph 0.7.2 the bar is positioned at the left edge of the plot area and half of it seems to be outside of the drawable area.  With version 0.7.1 this works as expected -- the bar is situated in the center of the plot area.

The following screenshots illustrate this:

* Correct behaviour in 0.7.1: http://divbyzero.net/stuff/0.7.1.png

* Incorrect behaviour in 0.7.2: http://divbyzero.net/stuff/0.7.2.png

Test script:
---------------
 500, "height" => 300));
$graph = Image_Graph::factory("graph", $canvas);

$graph->add($plotarea = Image_Graph::factory("plotarea"));

$dataset = Image_Graph::factory("dataset");
$dataset->addPoint(42, 50);

$plot = $plotarea->addNew("bar", $dataset);

$width = (int)($graph->width() / $dataset->count());
$width = min(max($width, 15), 80);
$plot->setBarWidth($width, "px");

$graph->done();


Expected result:
----------------
The graph from 0.7.2 should look like the one in 0.7.1.

Image_Graph: Bug 9068 [Open] forceMaximum doesn't work as expected

Reported by david_wees@...
2006-10-17T19:39:37+00:00
PHP: 4.4.4 OS: Apache Package Version: 0.7.2

Description:
------------
When you use $AxisY->forceMinimum($ymin); you see the minimum value of y, the graph doesn't display any values of the user defined function less than the value request.

However, if you use $AxisY->forceMaximum($ymax); the graph displayed apparently uses $ymax for the display, instead of just ignoring values greater than the $ymax given.

Test script:
---------------
You can view the script at:

http://www.unitorganizer.com/download/vector.zip

Call the script with a function using:

vector.php?f=x^2&ymin=-10&ymax=10&xmin=-10&xmax=10

and try:

vector.php?f=-x^2&ymin=-10&ymax=10&xmin=-10&xmax=10

Expected result:
----------------
You should see with the first example that the graph displays a vertical line at 10 for values of the function that are greater than 10, but with the 2nd example, the graph displays nothing for values of the graph less than -10.

PHP: 4.3.9 OS: Linux (2.6.9 ?) Package Version: 0.7.2

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:
---------------
350, 'height'=>300, 'antialias' => 'native'));
$Graph = & Image_Graph::factory('graph', $driver);
$Graph->add($Plotarea = Image_Graph::factory('plotarea'));
/***************************Arrows************************/

/**************************PARAMATERS for PLOT*******************/

$Plot->setRange($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.

Description:
------------
Basically if you move the X axis to the top and flip the location of the labels to the outside they get cut off due to the top of the graph not moving down to accomodate them. This may also be true for flipped Y axis, have not tested that specifically. 

Test script:
---------------
On any graph do the following:

$AxisX->setFontAngle('vertical');
$AxisX->setAxisIntersection('max');
$AxisX->setLabelOption('position', 'inside');

Expected result:
----------------
Top of the graph to move down, labels to be displayed along the top in a vertical position.

Actual result:
--------------
Graph expands to fill the whole area and labels are put up into the Title area, likely being completely unreadable as they get cut off at the edge of the plot area.

But it automatically grids in the area with the dots being within a square of the grid rather than laying on the grid(as a traditional dot plot would generally do). This would be useful for building matrix representations of items. Basically box in lines around the axis values and then along the graph to box in the dots as well.
