Returning NAN after length of indicator.

const dataForge = require('data-forge');

const timeseries = require("timeseries-analysis");

const df = dataForge.readFileSync('binance_btc_usdt_time_5m.csv')
    .parseCSV()
    .dropSeries(['id', 'open', 'high', 'low', 'volume', 'startTime', 'endTime', 'tradeId']) // Drop certain columns

const newDfArray = df.toArray()

// Load the data
const t     = new timeseries.main(newDfArray);
const trend = t.lwma({
    period:    6
});

// returns https://chart.googleapis.com/chart?cht=lc&chs=800x200&chxt=y&chd=s:JDOLhghn0s92xuilnptvxz1110zzzyyvrlgZUPMHA&chco=76a4fb&chm=&chds=63.13,70.78&chxr=0,63.13,70.78,10
