edit: hvst.php

<?php ini_set('display_errors', 'on'); error_reporting(e_all); //set json header header("content-type: text/json");  include 'dbread.php'; //include 'correlate.php';  // last 5 days $days=5; $resultset1 = readdb('select timestamp,humidity,curtemp public."weatherdata" timestamp > now()-interval \''.$days.' days\';'); $fp = fopen('chart1.json', 'w'); fwrite($fp, json_encode($resultset1,json_pretty_print|json_numeric_check)); fclose($fp); ?>

here's sample of first few lines json output:

[     {         "timestamp": "2016-11-05 10:10:02.427425",         "humidity": 48,         "curtemp": 46     },     {         "timestamp": "2016-11-05 10:10:03.83401",         "humidity": 48,         "curtemp": 46     },
