mercurial - How to pull latest remote changes into remote repo (while using mqueues) -

-
the hg book recommends following workflow updating mqueue patches when remote repository has been updated link : hg qpush --all # qsave depricated (according hg qsave --help). appears have been # depricated since @ least 2010. additionally, qsave not working in environment # due organization's commit hooks hg qsave hg pull hg update --clean hg qpush -m -a the qsave command says: > command deprecated, use "hg rebase" instead. what new recommended workflow? want do: check out code make commits (probably not using mqueues) pull latest changes remote repo integrate changes repo. open rebase or merge workflow, want use kind of 3-way merge tool resolve conflicts edit : workflow using is: hg qpop --all hg pullup hg qpush # repeat until no patches left. the issue workflow generates .reject files. i know can a: hg qpush --all hg pull --rebase the issue don't know how abort or undo since modifies patches. think creates kind of

javascript - highcharts gapsize in milliseconds -

-
to plot set of values on time line i'm using highstock (highchart same). with highstock, it's possible set attribute gapsize mark a 'gap' (a blank hole of missing data) if more x intervals missing. the 'interval' calculated automatically smallest interval in serie. if dataset doesn't contain equally spaced intervals result unpredictable , shown in example, can full of gaps: https://jsfiddle.net/ptysyo4p/5/ series : [{ data : data, type: 'areaspline', fillopacity: .35, gapsize: 5, <-- responsible it ideal set size of interval manually or directly setting gapsize time interval instead number of intervals . possible? update: by looking in code think closestpointrange ( https://github.com/highslide-software/highcharts.com/search?p=1&q=closestpointrange&utf8=%e2%9c%93 ). ideas if can set @ without breaking anything?
