我对 Web 开发和 ExtJS 很陌生,我四处寻找有关更复杂概念的教程,但很难找到(是的,我找到了 Sencha 文档,但只提供了简单的概念)
我正在尝试为我的应用程序制作仪表板,在此仪表板中,我想要一个图表来详细概述我的统计信息。为了实现这一点,我试图通过制作一个单独的列表来为图表添加一个自定义过滤器,其中包含所有键的实例,当从列表中选择所述实例时,我希望图表只显示那些选定的实例。
我制作的图表:
Ext.define('view.chart.LocationStatisticsPerMonth', {
extend: 'Ext.chart.Chart',
alias: 'widget.LocationStatisticsPerMonthChart',
requires: [
'store.LocationStatisticsStore',
'store.TemplateStore',
'view.TitleToolbar'
],
constructor: function () {
this.store = Ext.create('store.LocationStatisticsStore', {
autoLoad: true, sorters: [{
property: 'YearMonth',
direction: 'ASC'
}]
});
this.store.getProxy().api.read = ServerControllers.Dashboard.LocationStatisticsPerMonth;
this.callParent(arguments);
},
animate: true,
shadow: true,
border: true,
legend: {
position: 'right'
},
axes: [{
type: 'Numeric',
position: 'left',
fields: ['TotalCount'],
title: false,
grid: true,
label: {
renderer: function (v) {
return String(v);
}
}
}, {
type: 'Category',
position: 'bottom',
fields: ['Location_Id'],
title: false,
label: {
rotate: {
degrees: 315
}
}
}],
series: [{
type: 'column',
axis: 'left',
gutter: 80,
xField: ['Location_Id'],
yField: ['TotalCount'],
tips: {
trackMouse: true,
width: 125,
height: 28,
renderer: function(storeItem, item) {
this.setTitle(String('Visitors: '+item.value[1]));
}
}
}]
});
我的商店
Ext.define('store.LocationStatisticsStore', {
extend: 'Ext.data.Store',
requires: ['model.LocationStatistics'],
model: 'model.LocationStatistics',
autoLoad: false,
remoteSort: false,
remoteFilter: false,
filterOnLoad: true,
sorters: [{
property: ['YearMonth' , 'Location_Id'],
direction: 'DESC'
}],
proxy: {
type: 'direct',
paramOrder: [],
api: {
read: ServerControllers.Reports.GetLocationStatisticsPerMonth
},
reader: {
type: 'json',
root: 'data',
totalProperty: 'totalRecords',
successProperty: 'success',
messageProperty: 'msg'
}
}
});
我的模型:
Ext.define('model.LocationStatistics', {
extend: 'Ext.data.Model',
idProperty: ['Location_Id'],
fields: [
{ name: 'YearMonth', type: 'string' },
{ name: 'Location_Id', type: 'int' },
{ name: 'Year', type: 'int' },
{ name: 'Month', type: 'int' },
{ name: 'TotalCount', type: 'int' },
{ name: 'AverageCountPerDay', type: 'int' }
]
});
有人愿意向我解释这个概念,链接教程或为我提供如何执行此操作的示例吗?
非常感谢您的帮助。
