i selectable objects snap center mouse cursor on click. modification allowed user in case moving object, no scaling, rotating, etc. updating position of object on mousedown or selected update position until moving event fired, object snap original position , begin following mouse. rect.on('moving', movehandler); function movehandler(evt) { var mousepnt = $canvas.getpointer(evt.e); rect.set({ left:mousepnt.x - rect.width*0.5 , top:mousepnt.y - rect.height*0.5}); this.setcoords(); } this i've come center selectable rectangle on cursor, i'm it's firing 2 movement events. there way override original positioning. or should instead write own mousedown , mouseup , , moving listeners mimic default dragging behavior? you solution fine if no rotating or scaling involved. you not executing more necessary if not .setcoords during movement optional since called on mouseup when translation finished. if want take mousedown approach, changing position

given pandas dataframe 2 columns, "atbats" , "hits", indexed date, possible recent historical batting average (average number of hits per atbat)? example, historical batting average fewest atbats greater 10. sort of rolling window conditional number of look-back periods. example, given: date, atbats, hits, 2017-01-01, 5, 2, 2017-01-02, 6, 3, 2017-01-03, 1, 1, 2017-01-04, 12, 3, 2017-01-04, 1, 0, on first day, there have been no historical atbats. on second day, 6. since both less 10, can nan or 0. on third day, on last 2 days , see 5+6 atbats average of (2+3)/(5+6) = 0.45 hits/atbat. on third day, on last 3 days , (2+3+1)/(5+6+1) = 0.5 hits/atbat. on fourth day, on last day , 4/16 = 0.25 hits/atbat. since last day has more 10 (16), don't need further. the final dataframe like: date, atbats, hits, pastatbats, pasthits, avg, 2017-01-01, 5, 2, 0, 0, 0, 2017-01-02,
