我正在尝试使用高图创建两个窗格的股票图表，如此处的http://www.highcharts.com/stock/demo/candlestick-and-volume/grid-light
我将JSON文件存储在这里https://api.jsonbin.io/b/5c9499db08b9a73c3abeec4a。
运行项目时，我不知道为什么数据无法正常工作，并且十进制值变大，以及如何将时间序列与我的7+ GMT系列同步。
这是我的项目：
$.getJSON('https://api.jsonbin.io/b/5c9499db08b9a73c3abeec4a', function (data) {
var X = [],
Y = [],
temperature = [],
dataLength = data.length,
// set the allowed units for data grouping
groupingUnits = [[
'week', // unit name
[1] // allowed multiples
], [
'month',
[1, 2, 3, 4, 6]
]],
i = 0;
for (i; i < dataLength; i += 1) {
X.push([
data[i][0], // the date
data[i][1] // the X
]);
Y.push([
data[i][0], // the date
data[i][2] // the Y
]);
temperature.push([
data[i][0], // the date
data[i][3] // the temp
]);
}
// create the chart
Highcharts.stockChart('container', {
rangeSelector: {
selected: 1
},

},

}],

您相对于数据定义了错误的
// A recursive function to print all subsets with the
// help of dp[][]. Vector p[] stores current subset.
function printSubsetsRec(arr, i, sum, p)
{
// If we reached end and sum is non-zero. We print
// p[] only if arr[0] is equal to sun OR dp[0][sum]
// is true.
if (i == 0 && sum != 0 && dp[0][sum])
{
p.push(arr[i]);
console.log(p);
return;
}
// If sum becomes 0
if (i == 0 && sum == 0)
{
console.log(p);
return;
}
// If given sum can be achieved after ignoring
// current element.
if (dp[i-1][sum])
{
// Create a new vector to store path
var b = p.slice(0);
printSubsetsRec(arr, i-1, sum, b);
}
// If given sum can be achieved after considering
// current element.
if (sum >= arr[i] && dp[i-1][sum-arr[i]])
{
p.push(arr[i]);
printSubsetsRec(arr, i-1, sum-arr[i], p);
}
}
// Prints all subsets of arr[0..n-1] with sum 0.
function printAllSubsets(arr, sum)
{
var n = arr.length
if (n == 0 || sum < 0)
return;
// Sum 0 can always be achieved with 0 elements
dp = [];
for (var i=0; i<n; ++i)
{
dp[i] = []
dp[i][0] = true;
}
// Sum arr[0] can be achieved with single element
if (arr[0] <= sum)
dp[0][arr[0]] = true;
// Fill rest of the entries in dp[][]
for (var i = 1; i < n; ++i)
for (var j = 0; j < sum + 1; ++j)
dp[i][j] = (arr[i] <= j) ? dp[i-1][j] ||
dp[i-1][j-arr[i]]
: dp[i - 1][j];
if (dp[n-1][sum] == false)
{
console.log("There are no subsets with sum %d\n", sum);
return;
}
// Now recursively traverse dp[][] to find all
// paths from dp[n-1][sum]
var p = [];
printSubsetsRec(arr, n-1, sum, p);
}
printAllSubsets([1,2,3,4,5], 10);
