与 Sencha 论坛中的这篇文章类似,我如何让这个(下图)中的标签垂直显示并与网格对齐?似乎这应该是图表基础,但也许我错过了一些东西。
这是带有代码的 jsFiddle:http: //jsfiddle.net/wilsjd/kg6Ps/8/
Ext.require('Ext.chart.*');
Ext.require(['Ext.Window', 'Ext.fx.target.Sprite', 'Ext.layout.container.Fit', 'Ext.window.MessageBox']);
Ext.define('CPI', {
extend: 'Ext.data.Model',
fields: [{
name: 'ReportingPeriod',
type: 'string'
}, {
name: 'PeriodAmount',
type: 'decimal'
}, {
name: 'CumulativeAmount',
type: 'decimal'
}]
});
var store1 = Ext.create('Ext.data.Store', {
model: 'CPI',
data: [{
ReportingPeriod: 'Period1',
PeriodAmount: 1,
CumulativeAmount: 1.2,
Target: 1
}, {
ReportingPeriod: 'Period2',
PeriodAmount: 1.2,
CumulativeAmount: .2,
Target: 1
}, {
ReportingPeriod: 'Period9',
PeriodAmount: 1.5,
CumulativeAmount: 0.8,
Target: 1
}]
});
var chart = Ext.create('Ext.chart.Chart', {
style: 'background:#fff',
animate: true,
theme: 'Category1',
store: store1,
width: 300,
height: 300,
renderTo: 'chart',
axes: [{
type: 'Numeric',
position: 'left',
fields: ['PeriodAmount', 'CumulativeAmount'],
title: 'CPI'
},{
type: 'Category',
position: 'bottom',
fields: ['ReportingPeriod'],
title: 'Reporting Period',
label : {
rotation:{degrees:270}
}
}],
series: [{
type: 'column',
axis: 'left',
xField: 'ReportingPeriod',
yField: 'PeriodAmount',
renderer: function(sprite, record, attr, index, store) {
var value = 0;
if(record.get('PeriodAmount')>=1){
value = 0;
}else{
value = 1;
}
var color = ['rgb(127, 255, 127)',
'rgb(255, 0, 50)'
][value];
return Ext.apply(attr, {
fill: color
});
}
}, {
type: 'line',
axis: 'left',
xField: 'ReportingPeriod',
yField: 'CumulativeAmount',
markerConfig: {
type: 'circle',
size: 4,
radius: 4,
'stroke-width': 0,
}
}]
});
chart.show();
