刷选和过滤其他强力双视觉效果

Question

如何使用 deneb 图表中的画笔过滤 power bi 中的其他视觉效果？

我的左侧有一个带有线条和条形标记的deneb图表，右侧有一个表格。

如果我逐一单击 2005 年至 2008 年的条形图（使用 ctrl 键选择多个条形图），它会过滤右侧的表格：

我现在想使用画笔来实现同样的事情：

这里是deneb规格：

{
  "data": {
    "name": "dataset"
  },
  "encoding": {
    "x": {
      "field": "year",
      "type": "ordinal"
    }
  },
  "layer": [
    {
      "mark": "line",
      "encoding": {
        "y": {
          "field": "world_gdp",
          "type": "quantitative"
        }
      }
    },
    {
      "mark": {"type": "bar", "width": 10},
      "encoding": {
        "y": {
          "value": 200
        },
        "y2": {
          "value": 210
        }
      },
      "params": [
        {
          "name": "brush_years",
          "select": {
            "type": "interval",
            "encodings": [
              "x"
            ]
          }
        }
      ]
    }
  ]
}

这是 Deneb 和 Vega-lite 的已知问题。请参阅https://github.com/deneb-viz/deneb/issues/223

解决方法是使用 Vega 而不是 Vega-lite。一个例子在这里：https://oneException.dev/news/1371652/deneb-s-cross-filter-brush-with-vega
