GChart is a pure-GWT client-side charting
solution. It does not require browser plugins,
external JavaScript, or server round-trips. The
package supports bar and x-y scatter charts,
custom ticks, left and right y axes, grid-lines,
annotated data points, and more.

Changes:
For easier time series charting, the standard GWT DateTimeFormat pattern syntax (e.g. dd/MM/yyyy HH:mm) is now supported in tick label format strings. For details and examples, see the setTickLabelFormat method's Javadocs.
