Re: [DISCUSS] Monitoring Client may need a new graphing engine
I have to agree with John that browser and platform support is the most important factor. Furthermore, I think the ajax library in library in Geronimo should continue to be shared across its webapps. On both of these accounts I would lean heavily towards upgrading the monitoring client (and the admin console) to Dojo 1.0.1 since it has IE Safari support and IMO is quickly becoming the open source ajax library of choice.

Re: [DISCUSS] Monitoring Client may need a new graphing engine
I had an off-line discussion with Erik about IE support of the various charting solutions. I *thought* Erik was saying that Dojo 0.4.3 charting works with IE, but just not always as expected. Actually, it turns out that Dojo 0.4.3 charting does not work with IE at all (similar to timeplot). That means that Dojo 1.0.1 charting is the only solution that will support IE. I agree with John Paul that browser support on windows is important. With this new understanding of IE support I'm now thinking Dojo 1.0.1 might be the better choice (even though I like the look and labels of Dojo 0.4.3 better). Joe was under the impression that IE worked with Paul McMahan wrote: I have to agree with John that browser and platform support is the most important factor.

From what I understand as far as Timeplot goes, it's due to Timeplot using 'Canvas' to do the rendering, which is not something that Internet Explorer has support for, and they are looking to begin using an open sourced google library called 'explorer canvas' to enable internet explorer support in the next release (reference here on their site: http://simile.mit.edu/wiki/Timeplot_Limitations ) As far as current dojo (0.4.3) is concerned, from what i can tell - any browser on a Mac will not draw any of the surrounding text on a graph... at least as implemented in a portlet. (The Axis labels and values are absent). I have also been unable to get IE6 to draw the graphs in the current portlet as implemented. --kevan Thanks for taking a look at the license Kevan. -Thanks, Erik B. Craig

Re: [DISCUSS] Monitoring Client may need a new graphing engine
I agree with Joe. I think having the x/y axis labels are very important, especially if we wish to allow the admin to customize these graphs. It will be rather confusing without them (unless we can write an extension for Simile to add this feature). Also, I like the curved lines. --Viet
Re: [DISCUSS] Monitoring Client may need a new graphing engine
+100 for simile. IMO the curved lines in dojo 0.4.3 are really bogus and basically lie about how much data you have. I'd recommend you not use them if possible. The mouse-over feature is very useful, you can easily read actual numbers off the graph multi-series display is pretty much essential IMO to get a reasonable view of data on only one web page. The multi-series display example you point to indicates the meaning of each data series in text above the graph. How is this worse than labelling the y-axis? thanks david jencks On Dec 6, 2007, at 6:29 PM, Erik B.
