Is there a parameter for the Dygraphs legend option (e.g., 'never') that will hide the legend entirely? I'm looking for the opposite of "always", and hoping there is a cleaner way to suppress the legend than associating it with its own labelsDiv, creating that div, and styling that div's visibility as "hidden".
As already stated, there doesn't seem to be an explicit option right now, but you can easily set the labelsDivWidth option to 0 to hide it.
options.labelsDivWidth = 0;
