问题描述



应该如下所示:





有什么想法我会错了吗?我在这里找到了此问题 NVD3设置已展开为默认,但答案对我没有效果






我的nv.addGraph代码 b

  var data = [{
key:Price,
color:#4C73FF,
values :[[1443621600000,71.89],
[1443619800000,75.51],
[1443618000000,68.49],
[1443616200000,62.72],
[1443612600000,70.39] $ b [1443610800000,59.77]]
}];

nv.addGraph(function(){
var chart = nv.models.linePlusBarChart()
.margin({top:20,right:40,bottom: left:40})
.x(function(d,i){return i})
.y(function(d){return d [1]})
.color .scale.category10()。range());

chart.xAxis.tickFormat(function(d){
var dx = data [0] .values [d]&& ; data [0] .values [d] [0] || 0;
//以小时为单位的返回时间:
return d3.time.format('%I:%M') (dx))
});

chart.y1Axis
.tickFormat(d3.format(',f'));

图表。 y2Axis
.tickFormat(function(d){return'$'+ d3.format(',f')(d)});

chart.bars.forceY([0] );
chart.lines.interactive(false);
chart.height(300);
chart.noData(目前没有要显示的数据。
$ b //删除图例:
chart.showLegend(false);

d3.select('#chart svg')
.datum(data)
.transition()。duration(500)
.call(chart);

nv.utils.windowResize(chart.update);

return chart;
});


解决方案


$ b

  d3.select('#chart svg')
.datum(res)
.transition
.call(chart);

chart.update(); //< - 需要添加这个

// nv.utils.windowResize(chart.update);

以下行是完全无用的:
nv.utils。 windowResize(chart.update);



我移动了chart.update,显然这是需要触发时间跨度展开。

I have the latest d3 and nvd3 libraries in the plnkr above. When you first view the chart, you will notice that all the timespan ticks 09:00, 08:30, 08:00 etc are all squished/overlaid on top of each other on the left xAxis.

Now the timespans will not correctly stretch the length of the chart until the user either clicks on the time range finder below the chart, or resizes the window.

Currently the chart looks like this on first load:

When it should looks like this:

Any idea where I'm going wrong? I found this question here NVD3 Set Expanded as default however the answer did not work for me.


My nv.addGraph code

var data =[{
    "key" : "Price",
    "color" : "#4C73FF",
    "values" : [ [ 1443621600000 , 71.89],
                 [ 1443619800000 , 75.51],
                 [ 1443618000000 , 68.49],
                 [ 1443616200000 , 62.72],
                 [ 1443612600000 , 70.39],
                 [ 1443610800000 , 59.77]]
}];

nv.addGraph(function() {
      var chart = nv.models.linePlusBarChart()
          .margin({top: 20, right: 40, bottom: 50, left: 40})
          .x(function(d,i) { return i })
          .y(function(d) { return d[1] })
          .color(d3.scale.category10().range());

      chart.xAxis.tickFormat(function(d) {
          var dx = data[0].values[d] && data[0].values[d][0] || 0;
          // return time in hours:
          return d3.time.format('%I:%M')(new Date(dx))
      });

      chart.y1Axis
          .tickFormat(d3.format(',f'));

      chart.y2Axis
          .tickFormat(function(d) { return '$' + d3.format(',f')(d) });

      chart.bars.forceY([0]);
      chart.lines.interactive(false);
      chart.height(300);
      chart.noData("There is no Data to display at the moment.");

      // Remove legend:
      chart.showLegend(false);

      d3.select('#chart svg')
          .datum(data)
          .transition().duration(500)
          .call(chart);

      nv.utils.windowResize(chart.update);

      return chart;
  });

解决方案

Just figured it out!

d3.select('#chart svg')
    .datum(res)
    .transition().duration(500)
    .call(chart);

chart.update();  // <- Needed to add this

// nv.utils.windowResize(chart.update);

The following line was completely useless: nv.utils.windowResize(chart.update);

I moved the chart.update out of that and apparently this is what was needed to trigger the timespan to stretch out.
