カナダドルの場合はbitcoin price and trade volume historyです。しかし、このリストは大変です。これまでに行われたすべての取引が表示されます。だから私はそれを1日に数百のデータポイントから週に1つに減らそうとしている。ボリュームを合計して価格を平均化することによって、データポイントを時間間隔の間隔に基本的に「単調化」します。このようにして、より単純なデータでは、my line chartの行はずっとよく見えるはずです。
残念ながらスクリプトは機能しません。 CSVは2次元配列であると仮定していますが、現実には1次元だけだと思いますか? CSVを適切に解析するように変更するにはどうすればよいですか?
function simplifyData(data_set) {
interval_length = 3600; // hourly intervals
last_price = 0;
idx = 0;
while (idx < data_set.length) {
// reset value for this interval
volume = 0;
price_sum = 0;
count = 0;
timestamp = data_set[idx]['timestamp'] + interval_length;
// get sums for this interval
while (data_set[idx]['timetamp'] < timestamp) {
volume += data_set[idx]['volume'];
price_sum += data_set[idx]['price'];
count++;
idx++;
if (idx >= data_set.length)
break;
}
// get average price
price = count > 0 ? price_sum/count : last_price;
last_price = price;
// add new row to monotized data array
monotized_data.append([
