需要dojo散点或气泡图的例子

问题描述

我很难理解如何处理dojo中的散点图和气泡图。有谁有一个例子或好的文档，我可以看看帮助我吗？

解决方案

不像任何其他图表，每点需要两个输入的区域x和y）

气泡图每点需要三个输入（x，y和气泡的大小） strong>

气泡图示例：

  require（[
dojox / charting / Chart，
dojox / charting / themes / MiamiNice，
dojox / charting / plot2d / Bubble，
dojox / charting / plot2d / Markers 
dojox / charting / axis2d / Default，
dojo / domReady！
]，function（Chart，theme）{
 var d1 = []; 
 for（var i = 0; i  d1.push（{x：i，y：parseInt（Math.random（）* 30），size： parseInt（Math.random（）* 10）}）; 
 //或者你可以把size：1简化为
} 
 var chart = new Chart（container）; 
 chart.addPlot（default，{
 type：bubble
}）; 
 chart.addAxis（x）; 
 chart.addAxis（y，{vertical：true，fixLower：major，fixUpper：major}）; 
 
 //添加一系列数据
 chart.addSeries（Demo，d1）; 
 chart.render（）; 
}）; 
  

散点图与任何其他点图类似，除了x轴值可以在浮点数（或双）类型。

分散图示例：

  require（[
dojox / charting / Chart，
dojox / charting / themes / MiamiNice，
dojox / charting / plot2d / Scatter，
 dojox / charting / plot2d / Markers，
dojox / charting / axis2d / Default，
dojo / domReady！
]，function（Chart，theme）{
 var d1 = []; 
 for（var i = 0; i  d1.push（{x：i，y：parseInt（Math.random （）* 30）}）; 
} 
 var chart = new Chart（container）; 
 chart.addPlot（default，{
 type：Scatter 
}）; 
 chart.addAxis（x）; 
 chart.addA xis（y，{vertical：true，fixLower：major，fixUpper：major}）; 
 
 //添加一系列数据
 chart.addSeries（Demo，d1）; 
 chart.render（）; 
}）;

I'm having a bit of trouble understanding how to tackle the scatter and bubble chart in dojo. Does anyone have an example or good documentation I can look at to help me out?

解决方案

unlike any other chart (line,bar,area which takes two inputs per point , x and y)

bubble chart takes three inputs per point ( x, y , and size of bubble)

Bubble Chart Example:

            require([
              "dojox/charting/Chart",
              "dojox/charting/themes/MiamiNice",
              "dojox/charting/plot2d/Bubble",
              "dojox/charting/plot2d/Markers",
              "dojox/charting/axis2d/Default",
              "dojo/domReady!"
            ],function(Chart,theme){
             var d1 = [];
             for (var i = 0; i <= 10; i += 1){
                d1.push({x: i, y: parseInt(Math.random() * 30), size: parseInt(Math.random() * 10)});
                 // or you can put "size:1" for simplicity
             }
             var chart = new Chart("container");
             chart.addPlot("default", {
                 type:"Bubble"
             });
             chart.addAxis("x");
             chart.addAxis("y", {vertical: true, fixLower: "major", fixUpper: "major"});

             // Add the series of data
             chart.addSeries("Demo", d1);
             chart.render();
            });

Scattered charts are similar to any other point chart except the x axis values can be in float (or double) type.

Scattered Chart Example :

            require([
              "dojox/charting/Chart",
              "dojox/charting/themes/MiamiNice",
              "dojox/charting/plot2d/Scatter",
              "dojox/charting/plot2d/Markers",
              "dojox/charting/axis2d/Default",
              "dojo/domReady!"
            ],function(Chart,theme){
              var d1 = [];
              for (var i = 0; i <= 4; i += 0.1){
                  d1.push({x: i, y: parseInt(Math.random() * 30)});
              }
              var chart = new Chart("container");
              chart.addPlot("default", {
                 type:"Scatter"
              });
              chart.addAxis("x");
              chart.addAxis("y", {vertical: true, fixLower: "major", fixUpper: "major"});

              // Add the series of data
              chart.addSeries("Demo", d1);
              chart.render();
            });
