帶多列數據的酒窩多行

Question

如何製作多列數據的多折線圖？
數據爲例：

var data75 = [{"d":1,'a1':50,'a2':70}, 
{"d":2,'a1':90,'a2':71}, 
{"d":3,'a1':40,'a2':90}, 
{"d":4,'a1':15,'a2':70}, 
{"d":5,'a1':150,'a2':60}, 
{"d":6,'a1':53,'a2':20}, 
{"d":7,'a1':59,'a2':40}, 
{"d":8,'a1':30,'a2':50}, 
{"d":9,'a1':70,'a2':77}, 
{"d":10,'a1':52,'a2':72}, 
{"d":11,'a1':56,'a2':10}, 
{"d":12,'a1':57,'a2':40},]; 

d =軸線x;
a1和a2 =軸y在2個不同系列中;

Answer 1

1. 創建SVG對象

   var svg = dimple.newSvg('#div', 400, 200); 
   

2. 創建圖表

   var chart = dimple.chart(svg, data75); 
   chart.setBounds(20, 20, 360, 160); 
   

3. 創建/或/軸分配的圖表

   var x = chart.addCategoryAxis("x", "x"); 
   var y1 = chart.addMeasureAxis("y", "a1"); 
   var y2 = chart.addMeasureAxis("y", "a2"); 
   

4. 添加系列（軸的對做出一系列）

   myChart.addSeries(null, dimple.plot.line, [x, y1]); 
   myChart.addSeries(null, dimple.plot.line, [x, y2]); 
   

5. 繪製圖表

   myChart.draw();
