Cannot read property 'cssClass' of undefined

Getting an error with version 0.8.6 that didn't happen in 0.8.5. Created a plunker that reproduces the issue:

I see there was an API change, and backwards compatibility is not written perfectly ;)

just try using new configuration object:

instead of

tooltip: true,
tooltipOpts: {
    content: "%s %x, %y"
}

use

tooltip: {
    show: true,
    content: "%s %x, %y"
}

let me know if it helps!

This error seems to occur if you have flot.tooltip.js installed, but do not have tooltips turned on for a particular graph. (ie show: false or no tooltip config at all)

Also, this is a 2.8.X release it should have no new features or API changes only bug fixes. A backwards breaking change should only occur in an X.0.0 release so those of us who automatically pull in bugfix release don't end up with broken projects.

I agree with breaking changes and versioning, unfortunately I'm not an active maintainer of this repo, talk with @Roundaround

Seems that can be fixed with #138

#138 merged and released as 0.8.7, let me know if everything is fine
