Keen.io 如何使用 savedQueries() 绘制图表

Question

我正在尝试使用 savedQueries 绘制图表，但没有成功。 savedQueries 是否仅用于 Keen 中的 CRUD 查询，还是实际上也可以用于绘制图表？已从代码中删除密钥，给您带来的不便敬请谅解。

var client = new Keen({
  projectId: keen.project,
  writeKey: keen.writeKey,
  readKey: keen.readKey,
  masterKey: keen.masterKey
});
var savedQueries = client.savedQueries();
savedQueries.get("monthly-active-users", function(err, response) {
  if (err) {
    console.log(err);
  }
  console.log(response);
  var chart1 = new Keen.Dataviz()
    .el(document.getElementById('chart'))
    .chartType("area")
    .colors(["#6ab975"])
    .title("Monthly Active Users")
    .prepare();

  chart1
    .data(response)
    .render();

});

从保存的查询中响应 obj

我注意到您没有包含 Keen.ready() 函数。另外，我建议使用client.run 而不是client.get，因为它会运行查询并获得结果。

我继续创建了一个示例 JSFiddle：https://jsfiddle.net/pn14bs0L/2/

Keen.ready(function() {

  client.run("test-saved-query", function(err, response) {
    if (err) {
      // there was an error
    } else {
      var chart1 = new Keen.Dataviz()
        .el(document.getElementById('my_chart'))
        .chartType("areachart")
        .colors(["#6ab975"])
        .title("Monthly Active Users")
        .prepare();

      chart1
        .data(response)
        .render();
    }
  });

});

您可以在 JSFiddle 中看到这与一些测试数据一起工作。

注意：我假设您在这里使用的是热衷于 js，而不是敏锐的 dataviz.js。
