例
下面是一个简单的例子显示用法。<!DOCTYPE html> <html> <head> <link href="https://cdnjs.cloudflare.com/ajax/libs/extjs/6.0.0/classic/theme-classic/resources/theme-classic-all.css" rel="stylesheet" /> <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/extjs/6.0.0/ext-all.js"></script> <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/extjs/6.0.0/packages/charts/classic/charts.js"></script> <link href="https://cdnjs.cloudflare.com/ajax/libs/extjs/6.0.0/packages/charts/classic/classic/resources/charts-all.css" rel="stylesheet" /> <script type="text/javascript"> Ext.onReady(function() { Ext.create('Ext.chart.CartesianChart', { renderTo: document.body, width: 600, height: 200, flipXY: true, store: { fields: ['name', 'g1', 'g2'], data: [ {"name": "Item-0", "g1": 57, "g2": 59}, {"name": "Item-1", "g1": 45, "g2": 50}, {"name": "Item-2", "g1": 67, "g2": 43}, {"name": "Item-3", "g1": 45, "g2": 18}, {"name": "Item-4", "g1": 30, "g2": 90} ] }, //set legend configuration legend: { docked: 'right' }, //define the x and y-axis configuration. axes: [{ type: 'numeric', position: 'bottom', grid: true, minimum: 0 }, { type: 'category', position: 'left' }], //define the actual bar series. series: [{ type: 'bar', xField: 'name', yField: ['g1', 'g2'], axis: 'left' }] }); }); </script> </head> <body> </body> </html>
这将产生以下结果
