使用 D3 的条形图上的轴范围和域问题
Axis Range and Domain issue on bar graph using D3
我正在实现一个条形图，其中根据滑块的时刻，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 "ydata" 添加数据，但在这种情况下只反映前两个值。该值应为“0-9”、“20-29”、“40-49”、“60-69”、“80-89”和“100+”我的代码是此 link 的特色：

参见 this link 工作 plnkr - 我已将 rangePoints 最小化到 [300,0]。然后蜱将被安排在中间。希望能帮助到你。
