 /**
  * @fileoverview Test cases for the option "stepPlot" especially for the scenario where the option is not set for the whole graph but for single series.
  *
+ * TODO(danvk): delete this test once dpxdt screenshot tests are part of the
+ *     main dygraphs repo. The tests have extremely specific expectations about
+ *     how drawing is performed. It's more realistic to test the resulting
+ *     pixels.
