Get store in a var myStore;
Make a button with a handler;
Make a panel with a chart;

Ext.create('Ext.Button', {                                
   text : 'open chart',
   handler: function() {

       Ext.widget('mychart',{
            myStore: myStore
       });
   }
})

Ext.define('Path.to.Chart', {
    extend: 'Ext.panel.Panel',
        alias: 'widget.mychart',
    titleAlign: 'center',
    title: ('Chart'),
    width: '100%',
    height: 450,
    
    initComponent: function() {
        var me = this;
        if(!me.myStore){
            me.myStore= Ext.create('paht.store.newStore.Horas');
        }        
        Ext.applyIf(me, {
            items: [
                {
                    xtype: 'chart',
                    width: '600',
                    height: '400',
                    store: me.myStore,

......
               }
            ]
        });
        me.callParent(arguments);
    }
