假設我想要在Ext.js條形圖中顯示一些數據,並且希望我的數據繞y軸自定義值「1.0」旋轉(與傳統的「0.0」相比)。Ext.js圖表系列和軸
意思是,下面的圖片有負值表示反轉條,我想低於「1.0」的值在圖表上顯示爲反轉條。
有沒有辦法,我可以設置爲達致這一個設置?如果是這樣,它會在系列和軸定義?也許圖表本身?
所顯示的圖表的代碼如下:
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: 'CPI_P',
type: 'decimal'
}, {
name: 'CPI_C',
type: 'decimal'
}]
});
var store1 = Ext.create('Ext.data.Store', {
model: 'CPI',
data: [{
ReportingPeriod: 'Period1',
CPI_P: '1.9',
CPI_C: '1.2'
}, {
ReportingPeriod: 'Period2',
CPI_P: '1.2',
CPI_C: '1.1'
}, {
ReportingPeriod: 'Period3',
CPI_P: '0.1',
CPI_C: '0.5'
}, {
ReportingPeriod: 'Period4',
CPI_P: '-0.5',
CPI_C: '0.6'
}, {
ReportingPeriod: 'Period5',
CPI_P: '-0.9',
CPI_C: '0.8'
}, {
ReportingPeriod: 'Period6',
CPI_P: '-1.0',
CPI_C: '-0.6'
}, {
ReportingPeriod: 'Period7',
CPI_P: '-1.1',
CPI_C: '-0.7'
}, {
ReportingPeriod: 'Period8',
CPI_P: '-1.5',
CPI_C: '-0.8'
}]
});
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: ['CPI_P', 'CPI_C'],
title: 'CPI',
grid: true
}, {
type: 'Category',
position: 'bottom',
fields: ['ReportingPeriod'],
title: 'Reporting Period'
}],
series: [{
type: 'column',
axis: 'left',
xField: 'ReportingPeriod',
yField: 'CPI_P',
markerConfig: {
type: 'cross',
size: 3
},
renderer: function(sprite, record, attr, index, store) {
var value = (record.get('CPI_P') >> 2) % 2;
var color = ['rgb(213, 70, 121)',
'rgb(44, 153, 201)'
][value];
return Ext.apply(attr, {
fill: color
});
}
}]
});
chart.show();
UPDATE
如果我添加最小,以y軸我更接近(排序的)
...
axes: [{
type: 'Numeric',
position: 'left',
fields: ['CPI_P', 'CPI_C'],
title: 'CPI',
grid: true,
minimum: 1,
}....
It's th一個正確的想法,因爲酒吧現在與數字1相關,但我顯然需要保持圖上的酒吧。
