[英]Extjs 5.1 chart legend
I'm using Ext JS 5.1. 我正在使用Ext JS 5.1。
I have a very simple problem: 我有一个非常简单的问题:
I have a pie chart, and a button. 我有一个饼图和一个按钮。 When I click on the button, I bind a new store to my chart.
当我单击按钮时,我将新商店绑定到我的图表。 This works fine.
这很好。 But, if I make one element invisible in my chart (by clicking on one item in the legend) and bind a new store, the item at the same index of the new store will also be invisible.
但是,如果我使图表中的一个元素不可见(通过单击图例中的一项)并绑定一个新商店,则位于新商店相同索引处的项目也将不可见。 I don't want that.
我不要 Is there any way to set everything visible for a chart ?
有什么办法可以设置图表可见的所有内容?
Here is the Sencha Fiddle to clearly explain my problem. 这是Sencha小提琴,可以清楚地解释我的问题。
And the code if you're lazy! 还有代码,如果你很懒!
var storeA = Ext.create('Ext.data.Store', {
fields: ['name', 'value'],
data: [
{"name": "A-0", "value": 18.34},
{"name": "A-1", "value": 2.67},
{"name": "A-2", "value": 1.90}
]
});
var storeB = Ext.create('Ext.data.Store', {
fields: ['name', 'value'],
data: [
{"name": "B-0", "value": 4.34},
{"name": "B-1", "value": 54.67},
{"name": "B-2", "value": 18.90}
]
});
var donut = Ext.create('Ext.chart.PolarChart', {
title: 'Test',
animation: true,
width: 300,
height: 300,
renderTo: Ext.getBody(),
store: storeA,
legend: {
docked: 'bottom'
},
series: [{
type: 'pie',
angleField: 'value',
colors: ["#9aff4f", "#35b4e3", "#ffb400"],
donut: 20,
label: {
field: 'name',
display: 'inside'
},
highlight: true
}]
});
var button = Ext.create('Ext.Button', {
text: 'Click to change the pie store',
renderTo: Ext.getBody(),
margin: '10 10 10 63',
handler: function() {
if (donut.getStore() == storeA) {
donut.bindStore(storeB);
}
else {
donut.bindStore(storeA);
}
}
});
Ext.create('Ext.form.Label', {
html: '<br/><br/>To produce the bug:<br/><br/>' +
'1 - Make one item invisible by clicking on an item in the legend (A-0 for example).<br/>' +
'2 - Change the pie store by clicking on the blue button.<br/>' +
'3 - See with the new store the item at the same index is invisible. I don\'t want that to happen.<br/><br/>' +
'Is it possible to "enable" (make visible) every items of a pie chart?',
width: 300,
height: 300,
renderTo: Ext.getBody()
});
I took your suggested answer and created a complete example. 我接受了您的建议答案,并创建了一个完整的示例。 See the Sencha Fiddle for a live demo or refer to the code below.
