我想在EXTJS 3面板上實現帶有日期時間x軸的Highchart線圖，所以我使用了extjs適配器和Sencha論壇上提供的所有東西。 我正面臨一個非常奇怪的問題。我x軸上所有的標記都在同一個位置，以便它們重疊，如下所示：Highcharts和EXTJS 3：x軸重疊的標籤
這裏是我一起工作的代碼：
var store = new Ext.data.JsonStore({
url: '/graph',
fields: [
{name: 'datamesura', type: 'int'},
{name: 'despl_hor', type: 'float'},
{name: 'despl_ver', type: 'float'}
],
root: 'dades'
});
var datastore_task = {
run: function() {
store.load();
}
};
Ext.TaskMgr.start(datastore_task);
Ext.QuickTips.init();
var chart;
chart = new Ext.ux.HighChart({
series: [{
type: 'spline',
dataIndex: 'despl_hor',
name: 'Desplaçament horitzontal'
},{
type: 'spline',
dataIndex: 'despl_ver',
name: 'Desplaçament vertical'
}],
height: 500,
width: 700,
store: store,
animShift: true,
xField: 'datamesura',
chartConfig: {
chart: {
marginRight: 210,
marginBottom: 120,
zoomType: 'xy'
},
toolbar: {
itemStyle: {
color: '#4572A7',
cursor: 'pointer'
},
layout: {
xPosition: 'right',
yPosition: 'top',
x: 0,
y: -10
}
},
title: {
text: 'Prismes',
x: -20
},
subtitle: {
text: 'Desplaçament',
x: -20
},
xAxis: [{
title: {
text: 'Data',
margin: 20
},
labels: {
rotation: 270,
y: 35
},
type: 'datetime'
}],
yAxis: [{
title: {
text: 'Valor'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
}],
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'top',
x: 0,
y: 100,
borderWidth: 0
}
}
});
new Ext.Window({
title: 'Example',
layout: 'anchor',
items: [chart]
}).show();
圖和時間尺度是正確渲染。當我翻轉任何點時，即使日期在工具提示中也是正確的。但正如你所看到的，所有的標籤都在x軸的開始。
數據從一個JSON文件來在這樣的格式：

沒有人有線索？即使我非常喜歡Highcharts，我即將放棄並嘗試另一個圖表庫。
