C3中水平条形图标签中的长字符串

Question

C3似乎在将长字符串作为水平条形图中的标签处理时遇到问题。以下是一个示例代码段：

Answer 1

通过此thread，您可以使用axis.x.tick.multiline = false。

并像这样更新你的代码：

const char = c3.generate({
  data: {
    x: "x",
    columns: [
      labels, y
    ],
    type: "bar"
  },
  axis: {
    x: {
      type: "category",
      tick: {
        multiline:false
      }
    },
    y: {
      tick: {
        values: _.range(0, 7),
      }
    },
    rotated: true,
  },
  bindto: "#book-title-histogram",
  size: {
    height: 1400,
    width: 800,
  }
});

此外，您可以使用axis.x对象的不同选项来获得所需的结果（即：tick.multilineMax，x.height ...）。

在文档中，您可以找到许多与here一起使用的不同参数。

您还可以增加图表的总高度（使用修复高度或bookData.length）并执行以下操作：

const char = c3.generate({
  data: {
    x: "x",
    columns: [
      labels, y
    ],
    type: "bar"
  },
  axis: {
    x: {

      type: "category",
      tick: {
        multiline:true,
      }
    },
    y: {
      tick: {
        values: _.range(0, 7),
      }
    },
    rotated: true,
  },
  bindto: "#book-title-histogram",
  size: {
    height: bookData.length * 50
    width: 800,
  }
});
