Steps to Reproduce

这个例子是官网里的例子：

  tooltip: {
    position: "top"
  },
  animation: false,
  grid: {
    height: "50%",
    top: "10%"
  },
  xAxis: {
    type: "category",
    data: ["12a", "1a", "2a", "3a", "4a", "5a", "6a", "7a", "8a", "9a", "10a", "11a", "12p", "1p", "2p", "3p", "4p", "5p", "6p", "7p", "8p", "9p", "10p", "11p"],
    splitArea: {
      show: true
    }
  },
  yAxis: {
    type: "category",
    data: ["Saturday", "Friday", "Thursday", "Wednesday", "Tuesday", "Monday", "Sunday"],
    splitArea: {
      show: true
    }
  },
  visualMap: {
    min: 0,
    max: 10,
    calculable: true,
    orient: "horizontal",
    left: "center",
    bottom: "15%"
  },
  series: [{
    name: "Punch Card",
    type: "heatmap",
    encode: {
      x:0,
      y:1
    },
    data: [
      [11, 0, 2],
      [12, 0, 4],
      [13, 0, 1],
      [14, 0, 1],
      [15, 0, 3],
      [16, 0, 4],
      [17, 0, 6],
      [18, 0, 4],
      [19, 0, 4],
      [20, 0, 3],
      [21, 0, 3],
      [22, 0, 2],
      [23, 0, 5],
    ]
  }]
}

此时热力图可以被画出，但是如果将encode设置为同一列，则产生了空白图像，如下

option = {
  tooltip: {
    position: "top"
  },
  animation: false,
  grid: {
    height: "50%",
    top: "10%"
  },
  xAxis: {
    type: "category",
    data: ["12a", "1a", "2a", "3a", "4a", "5a", "6a", "7a", "8a", "9a", "10a", "11a", "12p", "1p", "2p", "3p", "4p", "5p", "6p", "7p", "8p", "9p", "10p", "11p"],
    splitArea: {
      show: true
    }
  },
  yAxis: {
    type: "category",
    data: ["Saturday", "Friday", "Thursday", "Wednesday", "Tuesday", "Monday", "Sunday"],
    splitArea: {
      show: true
    }
  },
  visualMap: {
    min: 0,
    max: 10,
    calculable: true,
    orient: "horizontal",
    left: "center",
    bottom: "15%"
  },
  series: [{
    name: "Punch Card",
    type: "heatmap",
    encode: {
      x:0,
      y:0
    },
    data: [
      [11, 0, 2],
      [12, 0, 4],
      [13, 0, 1],
      [14, 0, 1],
      [15, 0, 3],
      [16, 0, 4],
      [17, 0, 6],
      [18, 0, 4],
      [19, 0, 4],
      [20, 0, 3],
      [21, 0, 3],
      [22, 0, 2],
      [23, 0, 5],
    ]
  }]
}

Current Behavior
