@PanSpagetka What about the multiple lines in the chart showing the same value?

@mzazrivec see @PanSpagetka's line in the first comment:

[mzazrivec]

@dclarizio Yep, thanks. That line wasn't there before though.

@romanblanco does this need darga/yes flag as well?

[PanSpagetka]

@dclarizio I didnt test it in darga, this bug is probably present there. But the BZ is for cfme-future so I am not sure...

[romanblanco]

thanks, @PanSpagetka 😄

[dclarizio]

@PanSpagetka The bug was found in 5.6/Darga, so might need a fix there . . . I will flag the BZ for Euwe and we'll see if someone else wants it for Darga or not.
