Client-side GChart users can now produce order of magnitude faster (and much better looking) solidly connected line charts by using the new LINE_CANVAS symbol type, and bolting on (by implementing the new GChartCanvasLite interface) an external GWT canvas library.
The biggest performance improvements occur the first time a chart is drawn. To see how fast the new line charts are, check out the live demo's sine+cosine chart, which uses the canvas library from the GWT incubator's GWTCanvas. You can access this demo chart, as well as the v2.3 release notes, from Client-side GChart's home page: http://gchart.googlecode.com You won't have to load an external canvas library as long as your charts use only the original, HTML-element-based, symbol types. Thus, excluding LINE_CANVAS, GChart continues to deliver on its promise of providing basic, client-side, GWT charting using only the standard GWT distribution and its ~2K lines of Java. To get faster solidly connected line charts, though, I had to break this promise. But hopefully not for long: Once GWTCanvas graduates from the incubator, GChart can then freely use canvas, and still depend only on the standard GWT distribution. To increase the chance that this will happen sooner, rather than later, please vote for ("star") this GWT vector-graphics related issue: http://code.google.com/p/google-web-toolkit/issues/detail?id=1554 This Client-side GChart release is "brought to you by" (so to speak) GWTCanvas: http://code.google.com/p/google-web-toolkit-incubator/wiki/GWTCanvas John C.
