推荐答案

如果您查看源代码在这里。您会看到矩形的宽度是根据 rangeBand a>。似乎没有办法通过库的API来设置矩形的宽度。

If you look at the source here. You'll see that the width of the rectangle is calculated based on the number of items using rangeBand. There doesn't appear to be a way to set the width of the rectangle though the library's API.

如果您不想修补库，您可以 >可以创建具有零数据的额外假条，并提供一个标签格式化程序，如果值为零，则返回一个空字符串，但假设零不是数据集中的有效数字。

If you didn't want to patch the library, you could create additional fake bars with zero data and provide a label formatter that would return an empty string if the value was zero, but that assumes zero is not a valid number in your data set.
