javascript - Using slider on combined bar and linechart -

-

i build chart combining bar-chart , line-chart in d3.js , added slider updates x-axis not chart itself. attempts failed far. found nice example kind of similar: http://bl.ocks.org/dem42/3878029

i made fiddle, check out here: http://jsfiddle.net/karolinka/zpy0pqlu/10/ thinking in advance. code within slider function: 

        x.domain(d3.range(minv, maxv + 1));         xaxis.tickformat(function(i) {             return times[i];         });         svg.transition().duration(750)             .select(".x.axis").call(xaxis);          linescalex.domain(d3.range(minv, maxv + 1));         svg.transition().duration(750)             .select(".lines").attr("d", line);

in case anyones interested: line interpolation not nice, works now: http://jsfiddle.net/karolinka/zpy0pqlu/40/. in end hid additional elements jquery this: 

if(newtimes.length<5){    $(".bars:nth-child(5)").hide(); } else {     $(".bars:nth-child(5)").show(); }``

not best way guess if remove old elements , append them again, i´m not getting smooth transition.
