SVGGraph 3.0.1

SVGGraph 3.0.1 is a bugfix release, but there are a lot of changes in it. Sometimes you just have to rip up the floorboards to kill that annoying insect.*

The bug that caused all these changes is a very simple one: PHP automatically converts numbers to strings using its current locale. This makes perfect sense, but it meant that running SVGGraph in a locale that uses a comma instead of a full-stop for the decimal separator produced garbled SVG output. SVG always uses a full-stop for its decimal separator, with commas or spaces used for separating values.

SVGGraph 3.0

In my last news item I said I was going to work on version 3.0 of SVGGraph next, and that is what I have been doing. There is a lot more I want to do, but I could have spent months tinkering on the new version without ever being completely happy with it. So here it is.

The EmptyGraph

The example EmptyGraph above is something that I thought might be useful, and will become more useful when something else I have planned comes to fruition. At the moment it can be used to draw shapes and labels, plus it supports the graph title, border and background options. You can assign values, colours and links, but it doesn't do anything with them and you can get away with code as simple as this:

require 'SVGGraph/autoloader.php';

$graph = new Goat1000\SVGGraph\SVGGraph(600, 300);
$graph->render('EmptyGraph');

SVGGraph 2.30

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.

Shapes with added figures, marker and image

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.

JPEG Saver 5.2

JPEG Saver 5.2 is one of those versions that doesn't really look any different from the outside. On the inside there have been some important changes, making some existing things more stable and making some things that are still on my to-do list possible.

There are some visible updates - I've made a couple of simple changes in the dialogs that make it a bit easier to use. In the background and style editor dialogs where there are two colours I've added a button in between to swap them over. This also works in the background dialog when using a mode where only one colour is enabled, allowing you to flip between two colour options.

The folders list now shows the number of enabled folders at the top as well as the total number of folders in the list. This is especially useful for me, since I have a long list of folders that I turn on and off for testing different file types, EXIF and IPTC data, automatic rotation, etc.

SVGGraph 2.29

SVGGraph 2.29 is another version that mostly changes thing internally, but there are a few more visible changes too. The most obvious change should be apparent in the example below.

Box division style

Thinking inside the box

Both division_style and subdivision_style (and their _h and _v variants) now support a new style called "box". The Y axis in the bar graph shows how they behave with this new style when the labels are at the division marks, and the X axis shows what happens when the labels are between the marks (usually for bars) - the box is drawn around the label instead of inside it. I have used the subdivision_h option set to 0.5 to enable subdivisions on the X axis so you can see what they look like - they would not normally be displayed.
