Gridlines and axis labels make charts easier to understand. They give + the lines a clear scale. Unless you tell it otherwise, dygraphs will choose + a y-axis and set of gridlines which include all of your data.
+ +If you have many series with different scales, this will compress the + variation in all but the largest one. Standard ways to deal with this + include secondary y-axes and log scales.
+ +If neither of these is to your liking, you can manually rescale your + series and undo that scaling for the hover values. This demo shows how to + do it.
