Anychart tagCloud scale

Question

我正在开发一个简单的网站在超文本标记语言，我需要添加一个tagCloud图表。我不明白如何设置缩放方法。在文档中解释了使用anychart.scales.log()，但我需要一个图表，您可以在其中看到一个单位是否具有较高的频率，但同时我需要具有较低频率的单位不是不可见的。在我的例子中，对数方法将所有数据放在几乎相同的大小。

​

    anychart.onDocumentReady(function() {

      var data = [
        {"x": "CompanyNameLTD", "value": 10000, category: "Technology"},
        {"x": "CompanyNameLTD", "value": 1000, category: "Technology"},
        {"x": "CompanyNameLTD", "value": 100, category: "Technology"},
        {"x": "CompanyNameLTD", "value": 5000, category: "Technology"},
        {"x": "CompanyNameLTD", "value": 1000, category: "Technology"},
        {"x": "CompanyNameLTD", "value": 8000, category: "Seller"},
        {"x": "CompanyNameLTD", "value": 4000, category: "Seller"},
        {"x": "CompanyNameLTD", "value": 1000, category: "Phone"},
        {"x": "CompanyNameLTD", "value": 10000, category: "Technology"},
        {"x": "CompanyNameLTD", "value": 1000, category: "Technology"},
        {"x": "CompanyNameLTD", "value": 100, category: "Technology"},
        {"x": "CompanyNameLTD", "value": 5000, category: "Technology"},
        {"x": "CompanyNameLTD", "value": 1000, category: "Technology"},
        {"x": "CompanyNameLTD", "value": 4000, category: "Seller"},
        {"x": "CompanyNameLTD", "value": 4000, category: "Seller"},
        {"x": "CompanyNameLTD", "value": 1000, category: "Phone"},
        {"x": "CompanyNameLTD", "value": 10000, category: "Technology"},
        {"x": "CompanyNameLTD", "value": 1000, category: "Technology"},
        {"x": "CompanyNameLTD", "value": 100, category: "Technology"},
        {"x": "CompanyNameLTD", "value": 5000, category: "Technology"},
        {"x": "CompanyNameLTD", "value": 1000, category: "Technology"},
        {"x": "CompanyNameLTD", "value": 8000, category: "Seller"},
        {"x": "CompanyNameLTD", "value": 4000, category: "Seller"},
        {"x": "CompanyNameLTD", "value": 1000, category: "Phone"},
        {"x": "CompanyNameLTD", "value": 10000, category: "Technology"},
        {"x": "CompanyNameLTD", "value": 1000, category: "Technology"},
        {"x": "CompanyNameLTD", "value": 1000, category: "Technology"},
        {"x": "CompanyNameLTD", "value": 5000, category: "Technology"},
        {"x": "CompanyNameLTD", "value": 1000, category: "Technology"},
        {"x": "CompanyNameLTD", "value": 4000, category: "Seller"},
        {"x": "CompanyNameLTD", "value": 4000, category: "Seller"},
        {"x": "CompanyNameLTD", "value": 1000, category: "Phone"}
      ];

      var chart = anychart.tagCloud(data);
      
      var tooltip = chart.tooltip();
      
      chart.tooltip().useHtml(true);
      
      tooltip.positionMode("point");
      
      tooltip.format("Goal: <b>{%value}");
      
      chart.angles([0])
      
      chart.container("wordCloudChart");
      
      chart.listen("pointClick", function(e){
         var url = "https://en.wikipedia.org/wiki/" + e.point.get("x");
         window.open(url, "_blank");
      });

      chart.background().fill({
      keys: ["#2a2a2a", "#2a2a2a", "#2a2a2a"],
      angle: 130,
      });

      chart.scale(anychart.scales.log());

      chart.draw();
    });

有人知道有没有更好的方法吗？

对于您提供的数据，我们建议使用默认的线性刻度(只需不应用对数刻度)。当最大值大于x1000的最小值甚至更大值时，适合使用对数尺度。您的数据范围在100到10000之间，在这种情况下，log scale将数据范围压缩到很大。
