SVGGraph 2.30
Published
This version of SVGGraph adds some more options for drawing things on the
graph, building on the existing shape option. The graph below is
the example from the shapes page with the
new features added.
The main difference in this version is the addition of the figure
option, which defines named shapes or groups of shapes that can then be used as
shapes, in other figures, or as markers on scatter and line graphs. The example
graph above has one figure defined and used three times for the red squares with
the shaded box over the top.
As well as adding figure support to shapes, there are two new shape types
available. The first is marker, which allows you to draw any of the
marker types on any graph. The star on the graph above is marker shape. The other
new shape is image, which adds an image to the graph.
There have also been some changes made to how axis labels are measured and
drawn, moving them into the DisplayAxis classes. This was mainly to
fix a bug with the the label placement on Radar graphs, but it does make sense
to keep all the axis display details in the same place.
Next version… SVGGraph 3.0?
With PHP5 now having reached the end of its supported life, I'm planning to make some more radical changes in the next version. I expect it to stay compatible with later PHP5 versions, but not all the way back to PHP5.2 as it is (supposed to be) now. The first thing I want to add in is a namespace, because not using one has been quite a pain for a while now.
Version 2.30 is available from the downloads page, or from GitHub / Packagist.
