What's going on with RGraph at the moment?

Curious about what's happening with RGraph at the current time? Well read on and see what's happening in the world of RGraph development.

Here's an update for about what's currently happening with RGraph at the moment. A new release is nearing finalisation and it has some interesting updates in it to the datagrid such as searching (both basic and regular expression) and paging (client and server based), minor updates to the ModalDialog that allow you to rotate the dialog when showing or hiding it, a couple of new datetime functions that mimic PHP functions and make handling dates and times far easier, layout updates to the various API documentation pages, the ability to add your event listener functions inline within the configuration instead of using the on() function and then there's my favourite. This I might hold back for version 6.23 - but text appearance on canvas has never been very good in my opinion. Certainly not as good as SVG. But now I've happened across a technique that makes the text appearance much better. Here's an example of a regular Bar chart that hasn't been tweaked followed by a version of the same chart but having been tweaked to improve the text appearance:

And here's a close-up of the "Gazza" label in the original (current) way that RGraph renders text and the new style:

Certainly an improvement I think that you'll agree! It still needs more work - especially in terms of working out coordinates for dynamic features. But the much improved appearance makes this a feature worth holding your breath for (but not too long - you do need to keep breathing!).
