javascript - Stop bars from centering in chart -


i creating bar chart using d3. looked @ this code , changed little bit.

however centering bars, , bars start immediate @ bar y axis.

it looks issue comes these 2 pieces of code:

var x = d3.scale.ordinal()     .rangeroundbands([0, width], .0);

and last line of one:

svg.selectall(".bar")     .data(graphobj)     .enter().append("rect")     .attr("class", "bar")     .attr("x", function(d) { return x(d.step); })

where x(d.step) responsible distance, x set @ var x = ...

somehow need change this, cant figure out. distance bit different since changed this:

var x = d3.scale.ordinal()     .rangeroundbands([0, width], .1);

to this:

var x = d3.scale.ordinal()     .rangeroundbands([0, width], .0);

but doesn't much.

can out here?

this code: 

        $('#chartdiv').html('');          var margin = {top: 10, right: 10, bottom: 35, left: 50},             width = 600 - margin.left - margin.right,             height = 250 - margin.top - margin.bottom;          var x = d3.scale.ordinal()             .rangeroundbands([0, width], .0);          var y = d3.scale.linear()             .range([height, 0]);          var xaxis = d3.svg.axis()             .scale(x)             .orient("bottom");           var yaxis = d3.svg.axis()             .scale(y)             .orient("left")             .ticks(10, "");          var svg = d3.select("#chartdiv").append("svg")             .attr("width", width + margin.left + margin.right)             .attr("height", height + margin.top + margin.bottom)             .append("g")             .attr("transform", "translate(" + margin.left + "," + margin.top + ")");           graphobj.foreach(function(d) {             d.step = +d.step;             d.temp = +d.temp;         });          x.domain(graphobj.map(function(d) { return d.step; }));         y.domain([0, d3.max(graphobj, function(d) { return d.temp; })]);          svg.append("g")             .attr("class", "x axis")             .attr("transform", "translate(0," + height + ")")             .call(xaxis);          svg.append("g")             .attr("class", "y axis")             .call(yaxis)             .append("text")             .attr("transform", "rotate(-90)")             .attr("y", 6)             .attr("dy", "-40px")             .style("text-anchor", "end")             .text("temperature");          svg.selectall(".bar")             .data(graphobj)             .enter().append("rect")             .attr("class", "bar")             .attr("x", function(d) { console.log(d.step, x.rangeband(), x(d.step)); return x(d.step); })             .attr("width", x.rangeband())             .attr("y", function(d) { return y(d.temp); })             .attr("height", function(d) { return height - y(d.temp); });          if ($('#chartdiv').css('left').replace('px','') < 0) {             $('#chartdiv').animate({                 left: 10             }, 1000);         }

you need add i variable .attr("x", function(d) { return x(d.step); }), so: .attr("x", function(d, i) { return x.rangeroundbands() * i; }), go through bars , place them 1 after other (this might need tweaking, can't without jsfiddle) should @ least on path of fixing without issues

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
