Image_Graph 0.6.0

2005-08-27T13:46:46-05:00

Image_Graph 0.5.0

2005-08-08T15:24:44-05:00

* Major change: removed Image_Graph_Driver and subclasses and uses Image_Canvas instead, which implies:
- Image_Graph_Color is obsolete, removing dependency on Image_Color (however Image_Canvas still depends on Image_Color)
- Fonts are simplified (all identified by name) and implemented using Image_Graph_Font class, removing Image_Graph_Font subclasses (only subclasses!), removing Fonts/ folder
- Added dependency on Image_Canvas
- Image/Graph/Config.php becoming obsolete since only IMAGE_GRAPH_SYSTEM_FONT_PATH was defined here. File kept for future purposes but not used.
- TTF Fonts (which were most often used) keep BC in 99% of the cases by replacing the 'ttf_font' factory alias mapping to 'Image_Graph_Font' and adding a mapping for 'Image_Graph_Font_TTF' to 'Image_Graph_Font'. Only case not working is when user manually includes Image/Graph/Font/TTF.php and creates and instance using 'new', which should only very, very rarely be the case
- BC break: If drivers were explicitly created before, they now have to be changed to Image_Canvas objects
* Added support for HTML image maps on line-, bar-, area-, smoothed line-, impulse-, band- and pie charts (more to come)
* Added 'tohtml' option for output directly in HTML using canvas and imagemap (if any)
* Added label option 'format' and 'dateformat' to Image_Graph_Axis to be able to format a label directly using sprintf() / date()
* Changed plus and cross markers to be outlined (by defalut) - visual improvement
* Added a star marker (Image_Graph_Marker_Star)
* Added legends to scatter/dot plots - the marker now shows in legends
* Performance optimization in Image_Graph_Axis_Category (with regards to heavy usage of array_search())
* Improved appearance of axis arrows
* Fixed Bug #4240 "Pie graph - color difference between graph and legend"
* Fixed Bug #4430 "Call-time pass-by-reference has been deprecated"
* Fixed Bug #4876 "mis-type in code -> undefined property"
* Bugs fixed/Features added in Image_Canvas
* Added Request #4451 "Unable to define IMAGE_GRAPH_SYSTEM_FONT_PATH outside of Config.php"
* Fixed Bug #4484 "SVG output problem with fill and alignment attributes of text"
* Fixed Bug #4586 "Content type image/jpg does not recognized by IE"

Image_Graph 0.4.0

2005-05-24T14:47:58-05:00

* Added support for antialiasing images when using GD (both using native GD method and Image_Graph own implementation)
* Added possibility to specify horizontal title alignment (left, right or center)
* Fixed an "off-by-one" problem with secondary axis
* Included all on-line examples in package
* Removed some memory leaks as described in bug #3958 "Memory leaks in Image_Graph 0.3.0-alpha"
* Fixed bug #4113 "Image_Graph_Driver_GD::pieSlice() warnings"
* Fixed bug #4333 "Legend division by zero error on PieChart"
* Fixed bug #4417 "Cannot use point ID as marker value"

Image_Graph 0.3.0

2005-02-25T03:37:23-05:00

Added possibility to use arrays of the type $data[$id] = array('x' => $x, 'y' => $y) for easy data addition to a dataset
* Added use of 'null' y-values in line plots (normal and smoothed) causing a break in the line (instead of dropping to zero)
* Added possibility to make one legend use multiple plotareas
* Added grouping to drivers (currently only fully supported by SVG driver)
* Added axis padding (padding inside the plotarea)
* Added Image_Graph_Axis::setFixedSize() to allow for alignment of axis on different plotareas when in a layout
* Added possibility to use padding with overlayed legends to make legend _not_ display fx. on-top of y-axis
* Added/improved support for multi line text using GD drivers
* Added support for antialiasing images when using GD (GD built in method)
* Implemented simple shadows (and removed shadow images from distribution)
* Fixed bug #3346 "double as data"
* Fixed a problem with normal multi-data bar charts not displaying expected bar width
* Fixed problem with legends when overlayed
* Fixed axis not displaying labels after resetting driver
* Fixed problem in SVG driver with vertical texts
* Fixed a problem with line axis marker on a secondary y-axis displaying vertically instead of horizontally
* Fixed problem with logarithmic axis not scaling properly
* Changed the way coordinates are calculated when adding titles to non-layout objects
* Changed which changes API causing minor BC breaks
- Renamed Image_Graph_Plot_Bar::barWidth() to Image_Graph_Plot_Bar::setBarWidth()
- Renamed Image_Graph_Plot_Bar::spacing() to Image_Graph_Plot_Bar::setSpacing()
- Removed Image_Graph_Layout_Plotarea, it being completely obsolete with introduction of Image_Graph_Axis::setTitle()
* Updated header comment blocks to conform to new standards as specified by RFC
* Performance optimizations

Image_Graph 0.3.0dev4

2005-01-28T03:22:32-05:00

Fixed problem with logarithmic axis causing an infinite loop

Image_Graph 0.3.0dev3

2005-01-27T16:36:55-05:00

* Added possibility to invert axis direction, fx. minimum at top or bottom
* Added methods to handle axis label customization (Image_Graph_Axis::setLabelOption() and Image_Graph_Axis::setLabelOptions())
* Minor change to the way GD driver(s) calculate height (so that fx. x-axis labels appear printed on the same baseline)
* Fixed axis so that forceMinimum() works with axis intersection
* Fixed PDF (PDFlib) driver to display images correctly
* Fixed factory method class name alias 'vector', tried to create Image_Graph_Dataset_Vector instead of Image_Graph_Dataset_VectorFunction
* Fixed a minor problem in category axis when adding more that one point with the same value, i.e. ('A', 10), ('A', 20)
* Fixed problem with grids on category axis
* Added possiblitity to add simple colors to Image_Graph_Line_Array
* Added id tags for line styles
* Performance optimization/tuning (axis, elements)
* Removed XML_SVG driver which was included by mistake (SWF driver remains, but has several unimplemented features)
* Added more tests
