我使用Highcharts显示的图表显示大约6天的数据，将缩放默认为1天。但是，它总是缩小到输入的最后24小时（变焦条一直向右）。
如何让它默认一直向左缩放（到输入的最早日期）？
代码：
$('#container').highcharts('StockChart', {
rangeSelector:{
buttons : [{
type: 'day',
count: 1,
text: 'Day'
},
{
type: 'hour',
count: 6,
text: ' 6-Hour '
}],
selected : 0,
inputEnabled: false
},
title : {
text : 'Temperature'
},
series : [
{
name: 'Temperature',
type: 'spline',
yAxis: 0,

如您所见，最早的日期是“2月3日16:00”，但它默认缩放开始“2月9日，15：00”。
