* Interesting member variables:
* dygraph_ - the graph.
* global - global attributes (common among all graphs, AIUI)
- * global_user - attributes set by the user
+ * user - attributes set by the user
* axes
* series - { seriesName -> { idx, yAxis, options }
* labels - used as mapping from index to series name.
