この日付の問題を修正するために、Stackoverflow の高値と安値を検索しました。ポイントが正しく設定された日付をチャートに表示するのに本当に苦労しています。
JSスクリプトは次のとおりです。
$(document).ready(function() {
var options = {
chart: {
renderTo: 'drawing',
zoomType: 'x',
width: 900,
height: 222
},
exporting: {
enabled: true
},
title: {
text: url+' - '+keyword
},
credits: {
text: 'Testing',
href: ''
},
xAxis: {
type: 'datetime'
},
yAxis: [{
allowDecimals: false,
reversed: true,
title: {
text: 'Rankings'
}
},],
tooltip: {
crosshairs: true,
shared: true
},
series: [{}]
};
var url = "****/chart.php";
$.getJSON(url, function(data1){
options.series = data1;
var chart = new Highcharts.Chart(options);
});
});
これは、JSON 用に PHP スクリプトが生成したものです。
