我正在实现一个条形图，其中按照滑块的时刻，行的垂直值会发生变化。我在Y轴域上添加特定范围并减小Y轴和X轴的厚度时遇到问题。对于Y轴，我希望通过数组添加数据＆＃34; ydata＆＃34;但在这种情况下只反映了前两个值。值应为＆＃34; 0-9＆＃34;，＆＃34; 20-29＆＃34;，＆＃34; 40-49＆＃34;，＆＃34; 60-69＆＃34;，＆＃ 34; 80-89＆＃34;和＆＃34; 100 +＆＃34;我的代码是此链接的功能：

请参阅this link工作plnkr - 我已将rangePoints最小化为[300,0]。然后，蜱将被安排在中间。希望能帮助到你。
var y = d3.scale.ordinal().domain(ydata.map(function(d) {
return d.val;
})).rangePoints([300, 0]);
