updateTimeFormat

Usage: Updates the time format. ONLY to be used with multi-line charts. Notice how chaining this method after make but before using and in turns the line chart into a multi-line chart.

updateTimeFormat(timeFormat)

Example:

tld3.upload('./data/multiLineData.csv')
    .then((data) => {
      tld3.make('LineChart')
          .updateTimeFormat('%Y%m%d')
          .using(data)
          .in('#linechart');
    })
    .catch((err) => {
      console.error(err);
    });
