谷歌图表:向烛台图表添加点

google-visualization charts javascript

创建了一个四分位数的烛台图表,用于合唱青蛙活动。尝试找出如何将实际数据点添加到图表中(使其成为组合图)。

以下是烛台图的代码:

我想在每个相关的烛台图上添加基础数据(带红点的散点图)。以便用户能够更好地可视化数据的传播,并最终识别异常值。

下面是前三个烛台图的基础数据。 [69, 78, 87, 91, 102, 109, 111, 112, 117, 118, 120, 126, 129, 131, 132, 134, 135, 136, 137, 138, 139, 140, 141, 142, 143, 144, 145, 146, 147, 148, 149, 150, 151, 152, 153, 155, 156, 157, 159, 160, 161, 162, 164, 165, 166, 167, 168, 169, 170, 171, 172, 173, 174, 175, 176, 177, 178, 179, 180, 181, 182, 183, 184, 190, 198, 200, 203, 204, 207, 208, 212, 216, 225]

[71, 72, 74, 78, 80, 82, 83, 84, 85, 87, 88, 89, 90, 91, 95, 96, 97, 99, 100, 101, 102, 103, 104, 105, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 123, 125, 127, 130, 131, 132, 133, 135, 137, 138, 140, 142, 143, 144, 146, 147, 149, 151, 152, 159, 161, 163, 164, 165, 168, 171, 172, 173, 175, 178, 181, 187]

[78, 88, 90, 94, 95, 96, 102, 103, 105, 106, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 122, 123, 124, 125, 126, 127, 129, 130, 131, 132, 133, 134, 135, 136, 137, 138, 139, 140, 141, 142, 143, 144, 145, 146, 147, 148, 149, 150, 151, 152, 153, 154, 155, 156, 157, 158, 159, 160, 161, 162, 163, 164, 165, 166, 167, 168, 169, 170, 171, 172, 173, 174, 175, 176, 177, 178, 179, 180, 181, 182, 183, 187, 198, 199, 200, 201, 206, 207, 210]

谢谢你的帮助。

这是我想到的。。。

为每个分散点向数据表中添加一个新列。。。

var scatterSeries = [
  [69, 78, 87, 91, 102, 109, 111, 112, 117, 118, 120, 126, 129, 131, 132, 134, 135, 136, 137, 138, 139, 140, 141, 142, 143, 144, 145, 146, 147, 148, 149, 150, 151, 152, 153, 155, 156, 157, 159, 160, 161, 162, 164, 165, 166, 167, 168, 169, 170, 171, 172, 173, 174, 175, 176, 177, 178, 179, 180, 181, 182, 183, 184, 190, 198, 200, 203, 204, 207, 208, 212, 216, 225],
  [71, 72, 74, 78, 80, 82, 83, 84, 85, 87, 88, 89, 90, 91, 95, 96, 97, 99, 100, 101, 102, 103, 104, 105, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 123, 125, 127, 130, 131, 132, 133, 135, 137, 138, 140, 142, 143, 144, 146, 147, 149, 151, 152, 159, 161, 163, 164, 165, 168, 171, 172, 173, 175, 178, 181, 187],
  [78, 88, 90, 94, 95, 96, 102, 103, 105, 106, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 122, 123, 124, 125, 126, 127, 129, 130, 131, 132, 133, 134, 135, 136, 137, 138, 139, 140, 141, 142, 143, 144, 145, 146, 147, 148, 149, 150, 151, 152, 153, 154, 155, 156, 157, 158, 159, 160, 161, 162, 163, 164, 165, 166, 167, 168, 169, 170, 171, 172, 173, 174, 175, 176, 177, 178, 179, 180, 181, 182, 183, 187, 198, 199, 200, 201, 206, 207, 210]
];

for (var i = 0; i < data.getNumberOfRows(); i++) {
  if (scatterSeries.length > i) {
    scatterSeries[i].forEach(function (y, index) {
      var colIndex = data.addColumn('number', 'Scatter ' + index);
      data.setValue(i, colIndex, y);
      addSeries(data.getNumberOfColumns() - 5);
    });
  }
}

为每个新列添加一个系列选项。。。

function addSeries(index) {
  options.series[index] = {type: 'scatter', pointSize: 1};
}

默认情况下,图表将为每个系列添加不同的颜色,
要对所有对象使用相同的颜色,请添加 'style' 每个新系列列的列
这可以使用数据视图完成。。。

var viewColumns = [];
for (var col = 0; col < data.getNumberOfColumns(); col++) {
  viewColumns.push(col);
  if (data.getColumnLabel(col).indexOf('Scatter') > -1) {
    viewColumns.push({
      type: 'string',
      role: 'style',
      calc: function (dt, row) {
        return 'red';
      }
    });
  }
}
var view = new google.visualization.DataView(data);
view.setColumns(viewColumns);
