请参阅此代码并尝试使用确切代码查找解决方案,因为我对EXTJS更新鲜:
var chart=Ext.create('Ext.chart.Chart', {
renderTo: Ext.getBody(),
store: store,
width: 400,
height: 250,
animate: true,
insetPadding: 30,
axes: [{
type: 'gauge',
position: 'gauge',
minimum: 0,
maximum: 100,
steps: 10,
margin: 10
}],
gradients: [{
'id': 'v-1',
'angle': 0,
stops: {
0: {
color: 'rgb(212, 40, 40)'
},
100: {
color: 'rgb(117, 14, 14)'
}
}
},
{
'id': 'v-2',
'angle': 0,
stops: {
0: {
color: 'rgb(180, 216, 42)'
},
100: {
color: 'rgb(94, 114, 13)'
}
}
},
{
'id': 'v-3',
'angle': 0,
stops: {
0: {
color: 'rgb(43, 221, 115)'
},
100: {
color: 'rgb(14, 117, 56)'
}
}
},
{
'id': 'v-4',
'angle': 0,
stops: {
0: {
color: 'rgb(45, 117, 226)'
},
100: {
color: 'rgb(14, 56, 117)'
}
}
},
{
'id': 'v-5',
'angle': 0,
stops: {
0: {
color: 'rgb(187, 45, 222)'
},
100: {
color: 'rgb(85, 10, 103)'
}
}
}],
series: [{
type: 'gauge',
field: 'value',
donut: 30,
colorSet: ['url(#v-1)', '#ddd']
}]
});
以下是代码的一部分。我只是想知道这可能是规格图具有多背景颜色,它们都是静态的吗?如0-25 =红色,25-50 =黄色,50-100 =绿色。

是。通过扩展量规系列,有人已经完成了做这件事的工作:http://www.sencha.com/forum/showthread.php?159879-KPI-Gauge
您可以下载.zip并添加到您的库中。那么你基本上可以这样做:
{
xtype: 'chart',
style: 'background:#fff',
animate: {
easing: 'elasticIn',
duration: 1000
},
store: store1,
insetPadding: 50,
flex: 1,
axes: [{
type: 'kpigauge',
position: 'left',
minimum: 0,
maximum: 100,
steps: 10,
margin: 0,
label: {
fill: '#333',
font: '12px Heveltica, sans-serif'
}
}],
series: [{
type: 'kpigauge',
field: 'data1',
needle: {
width: 2,
pivotFill: '#000',
pivotRadius: 5
},
ranges: [{
from: 0,
to: 70,
color: '#FF0000'
}, {
from: 70,
to: 90,
color: '#FFFF00'
}, {
from: 90,
to: 100,
color: '#00FF00'
}],
donut: 70
}]
