- * This class determines the charting area (in pixel coordinates), maps the
- * percentage coordinates in the DygraphLayout to pixels and draws them.
- * It's also responsible for creating chart DOM elements, i.e. annotations,
- * tick mark labels, the title and the x/y-axis labels.
- * This class is based on PlotKit.CanvasRenderer.
- *
+ * The DygraphCanvasRenderer class does the actual rendering of the chart onto
+ * a canvas. It's based on PlotKit.CanvasRenderer.
  * @param {Object} element The canvas to attach to
  * @param {Object} elementContext The 2d context of the canvas (injected so it
  * can be mocked for testing.)
