NVD3 折线图 X 轴刻度丢失 [英] NVD3 Line Chart X Axis Ticks Are Missing

问题描述

我使用 NVD3 在此处显示折线图:http://jsbin.com/xodaxafiti/2/edit?js,output

I am using NVD3 to display line chart here: http://jsbin.com/xodaxafiti/2/edit?js,output

但似乎 NVD3 会自动隐藏 XAxis 上的一些刻度标签，但仅隐藏边缘附近的刻度，即 2-3Oct 和 27-28Oct(第一个和最后一个刻度除外).我知道这是一个自动缩小，因为当我增加图表的宽度时，刻度开始出现.但是我发现这种减少行为很奇怪，并且 lineChart 没有像 multiBarChart 那样的 reduceXTicks 选项.

But it seems like NVD3 auto-hide some tickLabels on XAxis, but only those ticks near the edge, i.e. 2-3Oct and 27-28Oct (except the first and last tick). I know that this is an auto-reduce because when I increase the width of chart, the ticks start to show up. However I find that this reducing behaviour weird, and the lineChart does not have reduceXTicks option like multiBarChart.

我希望能够像这个那样自己控制减少行为:>

I want to be able to control the reducing behaviour myself like this:

var chart = nv.models.lineChart()       
   .useInteractiveGuideline(true)
   .margin({left: 80,top: 20,bottom: 120,right: 20});  

chart.xAxis.ticks(function() {
   return data[0].map(chart.x()).filter(function(d,i) {
      i % Math.ceil(data[0].values.length / (availableWidth / 100)) === 0;
   })
})

但是没有用.有人知道如何控制吗?

But it didn't work. Anyone has any idea how to control this?

推荐答案

减少行为有效，因为 showMaxMin 默认设置为 true.添加 .showMaxMin(false) 修复了问题:

The reducing behavior works because the showMaxMin set to true by default. Adding .showMaxMin(false) fixes the problem:

chart.xAxis.axisLabel("XAxisLabel")
    .showMaxMin(false)    
    .tickValues(tickvalues)        
    .tickFormat(function (d) {
      return tickformat[d];
      })
;
