Subject [DISCUSS] Monitoring Client may need a new graphing engine
Date Fri, 07 Dec 2007 02:29:17 GMT

Currently the monitoring client is using Dojo 0.4.3 charting, which does 
not necessarily behave as expected on Firefox/Safari on a mac, or on IE6 
on Windows.
I consider this to be a shortcoming, and given the new version of Dojo 
available (1.0.1), began investigating migrating the monitoring client 
over to the new version of Dojo, only to find that the new version of 
dojo appears to be a significant rewrite of the old code base, leaving 
out some features that I consider to be very visually pleasing and 
important for statistics viewing. While rummaging through the Dojo 
forums, I stumbled upon another Javascript graphing framework called 
Timeplot, which is part of the SIMILE project at MIT, and while this has 
it's own set of limitations... I'm trying to figure out the lesser of 
three evils before it comes a time that this monitoring plugin will be 
released, so that I have enough time (read: 3-5 days) to migrate the 
javascript generation over to something new if necessary.

I have created a small demonstration page that shows all three options 
graphed with the same data series, as well as weighing some of the 
advantages/disadvantages I could come up with,
Please have a look, and let me know your thoughts.

Personally, I think it would be really cool if we could use the Timeplot 
graphing libraries, as it is all BSD licensed and therefore friendly I 
believe (right, Kevan?)... and also EXTREMELY cool for showing multiple 
data series in one chart.
