編輯HighStock示例2窗格圖表,在軸上設置極值導致體積圖消失。下面是一個例子Highstock xAxis.setExtremes調用導致體積圖消失或繪製在兩個窗格圖表
我使用的是雙窗口的圖表,但是當我打電話setExtremes(因爲我想設置導航器的初始值),在大多數情況下的第一張圖是好的,然而,體積圖(這是我的第二個x軸)每次都跳到不同的高度(導致其從x軸脫離),有時它完全消失(儘管y軸本身看起來仍然很好)。
$(函數(){$ .getJSON( '?http://www.highcharts.com/samples/data/jsonp.php?filename=aapl-ohlcv.json&callback=',函數(數據){
// split the data set into ohlc and volume
var ohlc = [],
volume = [],
dataLength = data.length;
for (i = 0; i < dataLength; i++) {
ohlc.push([
data[i][0], // the date
data[i][1], // open
data[i][2], // high
data[i][3], // low
data[i][4] // close
]);
volume.push([
data[i][0], // the date
data[i][5] // the volume
])
}
// set the allowed units for data grouping
var groupingUnits = [[
'week', // unit name
[1] // allowed multiples
], [
'month',
[1, 2, 3, 4, 6]
]];
// create the chart
