我正在修补dimplejs中的多系列图表,并且对多轴逻辑有点困惑。
使用以下数据:
var data = [
{"Month":"01/2013", "Revenue":2000, "Profit":2000, "Units":4},
{"Month":"02/2013", "Revenue":3201, "Profit":2000, "Units":3},
{"Month":"03/2013", "Revenue":1940, "Profit":14000, "Units":5},
{"Month":"04/2013", "Revenue":2500, "Profit":3200, "Units":1},
{"Month":"05/2013", "Revenue":800, "Profit":1200, "Units":4}
]
我试图获得一个图表,按月计算我的收入和利润在同一y轴和我的单位在辅助y轴上。
使用下面的代码,我可以设法显示3系列。但是Profit系列与收入系列并没有真正在同一个轴上,整个事情似乎更像是一个黑客而不是一个合适的解决方案。
var chart = new dimple.chart(svg, data);
chart.setBounds(60,20,680,330);
var x = chart.addCategoryAxis("x", "Month");
var y1 = chart.addMeasureAxis("y", "Revenue");
chart.addSeries("null", dimple.plot.line, [x,y1]);
var y2 = chart.addMeasureAxis("y", "Units");
chart.addSeries("null", dimple.plot.bar, [x,y2]);
var y3 = chart.addMeasureAxis("y", "Profit");
chart.addSeries("null", dimple.plot.line, [x,y3]);
我想我的逻辑可能与如何正确地玩系列赛有关。任何帮助都会很棒。
非常感谢, 泽维尔
完整代码:
var svg = dimple.newSvg("body", 800, 400);
var data = [
{"Month":"01/2013", "Revenue":2000, "Profit":2000, "Units":4},
{"Month":"02/2013", "Revenue":3201, "Profit":2000, "Units":3},
{"Month":"03/2013", "Revenue":1940, "Profit":14000, "Units":5},
{"Month":"04/2013", "Revenue":2500, "Profit":3200, "Units":1},
{"Month":"05/2013", "Revenue":800, "Profit":1200, "Units":4}
]
var chart = new dimple.chart(svg, data);
chart.setBounds(60,20,680,330);
var x = chart.addCategoryAxis("x", "Month");
var y1 = chart.addMeasureAxis("y", "Revenue");
chart.addSeries("null", dimple.plot.line, [x,y1]);
var y2 = chart.addMeasureAxis("y", "Units");
chart.addSeries("null", dimple.plot.bar, [x,y2]);
var y3 = chart.addMeasureAxis("y", "Profit");
chart.addSeries("null", dimple.plot.line, [x,y3]);
x.dateParseFormat = "%m/%Y";
x.addOrderRule("Date");
chart.draw();

编辑:
自版本2起不再需要此版本。您现在可以使用composite axes。

我在这里看到问题,问题不在于多个轴,而是试图针对单个轴绘制多个度量,而Dimple还没有真正支持。我担心我现在能做的最好的事情是一些数据黑客攻击:
<div id="chartContainer">
<script src="http://d3js.org/d3.v3.min.js"></script>
<script src="/dist/dimple.v1.min.js"></script>
<script type="text/javascript">
var svg = dimple.newSvg("#chartContainer", 800, 400);
// Data hack required to get revenue and profit on the same axis, units are
// arbitrarily allocated to revenue but the values will be summed by date
var data = [
{"Month":"01/2013", "Metric":"Revenue", "Revenue/Profit":2000, "Units":4},
{"Month":"02/2013", "Metric":"Revenue", "Revenue/Profit":3201, "Units":3},
{"Month":"03/2013", "Metric":"Revenue", "Revenue/Profit":1940, "Units":5},
{"Month":"04/2013", "Metric":"Revenue", "Revenue/Profit":2500, "Units":1},
{"Month":"05/2013", "Metric":"Revenue", "Revenue/Profit":800, "Units":4},
{"Month":"01/2013", "Metric":"Profit", "Revenue/Profit":2000, "Units":0},
{"Month":"02/2013", "Metric":"Profit", "Revenue/Profit":2000, "Units":0},
{"Month":"03/2013", "Metric":"Profit", "Revenue/Profit":14000, "Units":0},
{"Month":"04/2013", "Metric":"Profit", "Revenue/Profit":3200, "Units":0},
{"Month":"05/2013", "Metric":"Profit", "Revenue/Profit":1200, "Units":0}
];
var chart = new dimple.chart(svg, data);
chart.setBounds(60,20,680,330);
// Add your x axis - nothing unusual here
var x = chart.addCategoryAxis("x", "Month");
// First y axis is the combination axis for revenue and profit
var y1 = chart.addMeasureAxis("y", "Revenue/Profit");
// Second is the units only
var y2 = chart.addMeasureAxis("y", "Units");
// Plot the bars first - the order of series determines their dom position
// from back to front, this means bars are at the back. It's important
// to note that the string here "Unit Sales" is NOT in the data. Any string
// not in the data is just used to apply a label which can be used for colouring
// as it is here and will also appear in tool tips
var bars = chart.addSeries("Unit Sales", dimple.plot.bar, [x,y2]);
// Use a simple line by metric for the other measures
var lines = chart.addSeries("Metric", dimple.plot.line, [x,y1]);
// Do a bit of styling to make it look nicer
lines.lineMarkers = true;
bars.barGap = 0.5;
// Colour the bars manually so they don't overwhelm the lines
chart.assignColor("Unit Sales", "black", "black", 0.15);
x.dateParseFormat = "%m/%Y";
x.addOrderRule("Date");
// Here's how you add a legend for just one series. Excluding the last parameter
// will include every series or an array of series can be passed to select more than
// one
chart.addLegend(60, 5, 680, 10, "right", lines);
chart.draw();
// Once Draw is called, this just changes the number format in the tooltips which for these particular
// numbers is a little too heavily rounded. I assume your real data isn't like this
// so you probably won't want this line, but it's a useful tip anyway!
y1.tickFormat = ",d";
</script>
</div>
这是目前的一个限制,但我刚才有一个非常好的实现的想法,我可以做这样的复合轴添加适当的支持。希望在不久的将来,这将是可能的。
祝你好运约翰
