问题描述
我想为nvd3中的气泡图设置自己的y轴标签。目前的标签是[1,2,3,4,5]。我想让他们显示为[2,4,8,16,32]。我发现了以下函数：
I am trying to have my own y axis labels for the bubble chart in nvd3. Currently the labels are [1,2,3,4,5]. I want them to be displayed as [2,4,8,16,32]. I found the following function,
chart.yAxis.tickValues(['2','4','8','16','32']);
但标签未被更改。我不能理解为什么。
But the labels are not being changed here. I am unable to understand why.
推荐答案
如果 y 值本身不在2-32范围内。现在该图表只有 y 的值高达2 +。
These tick values will not have any effect if the y values themselves are not within the 2-32 range. Right now that chart only has y values up to 2+.
因此，如果除了添加 chart.yAxis.tickValues（['2'，'4'，'8'，'16'，'32']）; 在您的问题中，您还对Data（JSON）标签中的代码进行了以下更改...
So, if in addition to adding chart.yAxis.tickValues(['2','4','8','16','32']); to the Chart Code/Javascript tab as you have in your question, you also make the following change to the code in the Data(JSON) tab...
y: Math.floor(Math.random() * 33) // change from y: random()
。 ..然后你会看到你指定的刻度值（2-32）出现在 y 轴。
...then you will see the tick values you specified (2-32) show up in the y axis.
注意：我假设你正在查看散点/气泡图。
NOTE: I assume you are looking at the Scatter / Bubble Chart.
