Sam, You've bumped into a couple limits of the diff chart feature. It doesn't work with additional role columns, including tooltips or annotations. We're not sure when we will get around to supporting roles.
But I don't see a problem with using log scale, or 'mirrorLog' with the diff chart. Could you provide a more complete example so I might be able to reproduce it? dan On Wed, Feb 12, 2014 at 9:57 AM, Sam Halliday <[email protected]>wrote: > btw, using scaleType: 'mirrorLog' fixes the log problem.
