Recommended Posts

Hi everyone.

Before I want to say, Im trying to make a project Raspberry PI 3 and Nodered.

I'm logging my data from device to Litesql everything is ok.

 

I just want to take this data from db and make a chart for a specific  time, like today, yesterday, last week, last mont, last year.

 

I found a code, and need to change this code for my project in javascript. Can some one help me. My db name is Test  and column name is Value

 

This code is working code, which is I take in internet , and I changed just db name and source.

// This will handle any device and any attribute as long as it is in the DB
var p_30d  = 1000*60*60*24*30 ; //30 Days
var p_7d  = 1000*60*60*24*7 ; //7 Days
var p_1d   =  1000*60*60*24 ; // 1 Day
var d = new Date();
var current = d.getTime();
var today0h = d.setHours(0,0,0,0);
var day = d.getDay();
var monday0h = today0h - (day + (day === 0 ? -6:1)) * p_1d;
var fromdate = 0;
var enddate = 0;
var sql = [];
var sourcelist = [];
var aggrlist = [];
var title = "";


// Get the period and the list of data sources 
// also set some default values if one or the other does not exist yet
sourcelist = context.get("sourcelist");
if (sourcelist===undefined) { // if running for the first time
    sourcelist = [];
}
aggrlist = context.get("aggrlist");
if (aggrlist===undefined) { // if running for the first time
    aggrlist = [];
}
fromdate = context.get("fromdate");
if (fromdate===undefined) {
    // set the period to a default if it is not selected yet
    fromdate = current-p_1d;
}
enddate = context.get("enddate");
if (enddate===undefined) {
    // set the period to a default if it is not selected yet
    enddate = current;
}

switch(msg.topic) {
    case "period":
        switch(msg.payload) {
            case "today":
                fromdate = today0h;
                enddate = today0h+p_1d;
                break;
            case "yesterday":
                fromdate = today0h-p_1d;
