Not sure if needed but interesting.\"\r\n - ( @PrometheusPi ) what about using not only the max error but also the means error with sigma error bars over time"},"comment":{"url":"https://api.github.com/repos/ComputationalRadiationPhysics/picongpu/issues/comments/140324494","html_url":"https://github.com/ComputationalRadiationPhysics/picongpu/issues/1105#issuecomment-140324494","issue_url":"https://api.github.com/repos/ComputationalRadiationPhysics/picongpu/issues/1105","id":140324494,"user":{"login":"ax3l","id":1353258,"avatar_url":"https://avatars.githubusercontent.com/u/1353258?v=3","gravatar_id":"","url":"https://api.github.com/users/ax3l","html_url":"https://github.com/ax3l","followers_url":"https://api.github.com/users/ax3l/followers","following_url":"https://api.github.com/users/ax3l/following{/other_user}","gists_url":"https://api.github.com/users/ax3l/gists{/gist_id}","starred_url":"https://api.github.com/users/ax3l/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/ax3l/subscriptions","organizations_url":"https://api.github.com/users/ax3l/orgs","repos_url":"https://api.github.com/users/ax3l/repos","events_url":"https://api.github.com/users/ax3l/events{/privacy}","received_events_url":"https://api.github.com/users/ax3l/received_events","type":"User","site_admin":false},"created_at":"2015-09-15T08:44:13Z","updated_at":"2015-09-15T08:44:13Z","body":"oh wait, does not make so much sense. because: the median should usually even for big errors be zero. if you abs the values, then the value says even less. so the only thing that gives you an indirect hint is then the sigma envelope.\r\n\r\nI am actually back to plotting the max(abs) over time, that is a quick indicator."}}
