Glowspot jQuery plugin

I've created a jQuery plugin version of the Glowspot script. The jQuery version is actually smaller and a bit more useful (or less useless) than the stand-alone version, as you can apply it to whatever you want instead of it just applying to links.

You can download it from the Glowspot page.

SVGGraph 2.4

The new version of SVGGraph comes with one new graph type, the MultiScatterGraph. Multiple data sets drawn as identical markers would be hard (impossible actually) to tell apart, so this version allows passing arrays of options for the marker size, type and colour used for data sets in both multi-line and multi-scatter graphs. The fill_under option for multi-line graphs now accepts an array of true/false values too.

Quite a lot of other things have changed internally to better support the axis options - the x-axis start, end and divisions are now controllable for the bar, line and scatter graphs using axis_min_h, axis_max_h and grid_division_h options. The horizontal bar graphs support the equivalent axis_max_v, axis_min_v and grid_division_v options as well.

The way scatter graphs accept data values has been improved too - see the line and scatter graph page for details. The new version is available for download from the downloads page.

TagCanvas 1.8

This is another one of those releases where it doesn't look like much has changed. I've added a new option called "frontSelect" which will disable the selection of tags that are on the far side of the cloud, but that's not the most interesting change.

The other, larger change is the new "txtOpt" option, which is turned on by default. This draws each text tag to its own canvas at the start of the script, then uses this canvas as an image instead of redrawing the text on each frame of the animation. It doesn't work in IE versions up to 8 because Explorer Canvas has trouble with images, but in all the other browsers it causes a real improvement in performance.

You can find the updated files on the TagCanvas page.

March 1.0

March? What's that? It's the stupid name I've given to my Javascript canvas clock script now that I've converted it into something usable.

The full details of what it does and how you can do things with it is on the new March page.

TagCanvas 1.7.1

Just a quick update to TagCanvas, this time fixing a bug that can cause an error message to appear in the console on Firefox. The error in question actually ends the click event handler just before it would have given up anyway, so it wouldn't change anything noticable, but this version cleans it up.

The updated files are on the TagCanvas page.
