GWTCanvas alternatives

[AThinerCoin]

I'm trying to create a chart using GWT. The chart has a grid and x
and y axis labels and at least one line indicating status over time.
The example code I got from a co-worker uses two classes the
com.google.gwt.widgetideas.graphics.client package: GWTCanvas and
Color.

The documentation about GWTCanvas says to use Canvas instead, but
Canvas has a very limited number of methods. How do I replicate these
methods?
- clear()
- setFillStyle(Color color)
- fillRect(double startX, double startY, double width, double height)
- setLineWidth(double width)
- setStrokeStyle(Color color)
- beginPath()
- moveTo(double x, double y)
- lineTo(double x, double y)
- stoke()

Any help is appreciated. Thanks!

Generally you grab a Context2d object from the canvas, and most of the methods you identified are exposed there.

See:

Context2d was exactly what I needed.  Thanks for all the help!
