我正在使用dimple.js,它基于d3.js.是否可以将数据标签添加到此示例http://dimplejs.org/examples_viewer.html?id=bars_vertical
中提到的条形图的每个条形图中<div id="chartContainer">
<script src="http://d3js.org/d3.v3.min.js"></script>
<script src="http://dimplejs.org/dist/dimple.v1.min.js"></script>
<script type="text/javascript">
var svg = dimple.newSvg("#chartContainer", 590, 400);
d3.tsv("/data/example_data.tsv", function (data) {
var myChart = new dimple.chart(svg, data);
myChart.setBounds(60, 30, 510, 305)
var x = myChart.addCategoryAxis("x", "Month");
x.addOrderRule("Date");
myChart.addMeasureAxis("y", "Unit Sales");
myChart.addSeries(null, dimple.plot.bar);
myChart.draw();
});
</script>
</div>

是的,这是非常有可能的。
在Dimple.js网站的“高级栏标签”部分中,他们展示了一个例子。 Click here要看到它。
我使用相同的技术将条形标签添加到您发布的代码段中。
注意:我保持评论几乎相同,以便您可以了解代码的内容。另外,为了测试目的,我更改了图表的大小。
试试这个:
<div id="chartContainer">
<script src="http://d3js.org/d3.v3.min.js"></script>
<script src="http://dimplejs.org/dist/dimple.v1.min.js"></script>
<script type="text/javascript">
var svg = dimple.newSvg("#chartContainer", 1100, 600);
d3.tsv("/example_data.tsv", function(data) {
var myChart = new dimple.chart(svg, data);
myChart.setBounds(60, 30, 900, 400)
var x = myChart.addCategoryAxis("x", "Month");
x.addOrderRule("Date");
var y = myChart.addMeasureAxis("y", "Unit Sales");
var s = myChart.addSeries("Sales", dimple.plot.bar);
myChart.draw();
// After drawing we can access the shapes and their associated data
// to add labels.
s.shapes.each(function(d) {
// Get the shape as a d3 selection
var shape = d3.select(this),
// Get the height and width from the scales
height = myChart.y + myChart.height - y._scale(d.height);
width = x._scale(d.width);
// Add a text label for the value
svg.append("text")
// Position in the centre of the shape (vertical position is
// manually set due to cross-browser problems with baseline)
.attr("x", parseFloat(shape.attr("x")) + width / 2 - 15)
.attr("y", parseFloat(shape.attr("y")) - height / 2)
// Centre align
.style("text-anchor", "middle")
.style("font-size", "10px")
.style("font-family", "sans-serif")
// Make it a little transparent to tone down the black
.style("opacity", 0.7)
// Format the number
.text(d3.format(",.1f")(d.yValue / 1000) + "k");
});
});
</script>
希望这有帮助!
