This version of SVGGraph mainly fixes a few bugs, but I have added one new option too. It doesn't do anything visual, so there is no example graph to show for it.
The new option is
datetime_key_format, for use with the
datetime_keys option added in version 2.23. This new option allows
you to specify a format for parsing your keys instead of relying on PHP
recognising the format. The format string is described on this PHP manual page:
The first of the bugs fixed in this version is also related to the
datetime_keys option, solving a nasty error when using multiple
dataset graphs without structured data.
The other bugs are a bit more obscure. The
provided with dual-Y axis options (which are unsupported anyway). Per-dataset
stroke_width options were failing when one of the widths was 0.
Finally, the last bug was in using using structured data with the default
structure, an integer key field and values with string keys. It's
hard to explain the bug, but it was easy to fix.
I found a few of these bugs while working on the new documentation for the options. It's not ready yet, but I'm hoping to get it finished in the next couple of weeks. There are more options than I thought so it is taking me a long time to work through them, figuring out what they do, tagging and cross-referencing them. I'm also checking that they work, which is taking even more time.
