我正在创建标签冲突的 RGraph 饼图。虽然我使用labels.sticks
属性来解决这个问题,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:
为了解决标签冲突问题,我使用以下选项:
options: {
labels: {
self: labels,
sticks: [10, 20, 30, 40, 50, 60, 70, 80, 90, 100],
},
根据 RGraph 文档:
labels.sticks 规定显示标签的棒。这也可以是一系列棒长度 - 如果您遇到标签冲突,这可能很有用。默认值:假
