我正在创建标签相互冲突的RGraph饼图。尽管我正在使用labels.sticks
属性来解决此问题,但它对输出没有影响。
这是我绘制饼图的代码:
<script type="text/javascript">
$(document).ready(function(){
// Some data that is to be shown on the pie chart. It should be an array of numbers.
var data = [6.3, 2.1, 1.1, 3.2, 7.4, 10.5, 5.3, 27.4, 1.1, 4.2];
var labels = ['Data Loggers 6', 'Data Translation 2', 'Energy Loggers 1', 'Hobo 3', 'iButton 7', 'ICP 10', 'MCC 5', 'Monnit 26', 'Orchestrator 1', 'Sensors 4'];
for(var i = 0; i < data.length; i++)
{
labels[i] = labels[i] + ', ' + data[i] + '%';
}
var colors_arr = new Array('#00FFFF', '#7FFFD4', '#FFE4C4', '#0000FF', '#8A2BE2', '#A52A2A', '#7FFF00', '#FF7F50', '#B8860B', '#A9A9A9', '#8B008B', '#FF1493', '#228B22', '#DAA520', '#20B2AA', '#87CEFA', '#6B8E23', '#FF0000', '#FFFF00', '#F5DEB3');
var colors = new Array();
for(var i = 0; i < data.length; i++)
{
colors[i] = colors_arr[i];
}
// Create the Pie chart
var pie = new RGraph.Pie({
id: 'report_prospects_qty_products_canvas' ,
data: data,
options: {
labels: {
self: labels,
sticks: [10, 20, 30, 40, 50, 60, 70, 80, 90, 100],
},
tooltips: {
self: labels,
//event: 'onmousemove',
},
shadow: false,
strokestyle: 'transparent',
title: {
self: 'Products',
bold: false,
y: 10
},
radius: 70,
colors: colors,
text: {
size: 8,
color: "red",
angle: 45
},
},
}).roundRobin();
$('#report_prospects_qty_products_wrapper').mouseout(function(){
// Hide the tooltip
RGraph.hideTooltip();
// Redraw the canvas so that any highlighting is gone
RGraph.redraw();
});
});
</script>
HTML
<!-- Put this where you want the chart to show up: -->
<div id="cvs_wrapper">
<!-- An example of using CSS to resize the canvas tag. -->
<canvas id="report_prospects_qty_products_canvas" width="600" height="250" style="width:100%;">[No canvas support]</canvas>
</div>
输出:
要解决标签冲突问题,我正在使用以下选项:
options: {
labels: {
self: labels,
sticks: [10, 20, 30, 40, 50, 60, 70, 80, 90, 100],
},
根据RGraph文档:
labels.sticks规定显示标签的粘贴条。这个 也可以是棍子长度的数组-如果您 遇到标签冲突。默认值:false
仅供参考,我正在使用// version: 2015-05-24
答案 0 :(得分:0)
从您发布的配置代码来看,我猜您可能正在使用旧版本。当前版本(当前为5.0)使用了更好的标签排列方式,因此不会发生冲突(除非您有很多标签)。
这里有一个演示页面,很好地展示了这种新方法:

与此相关的代码与您可能习惯的代码没有什么不同>
labels = [ 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday' ];
new RGraph.Pie({
id: 'cvs',
data: [20,1,1,1,1,1,1],
options: {
tooltips: labels,
labels: labels,
shadow: false,
colorsStroke: 'rgba(0,0,0,0)',
exploded: 0
}
}).roundRobin();
