DateFormat chart option can be a variable or function

[abdul-qadirdeveloper]

for globalization support chart.exporting.csv.dateFormat should be either a variable or a function, therefore, custom dateFormat may be provided for parsing dates using function. In this regard following code changes are requested. if (series.xAxis.isDatetimeAxis) { xData = Highcharts.map(xData, function (x) { if (typeof dateFormat == 'function') {
return dateFormat(x); } else { return Highcharts.dateFormat(dateFormat, x) } }); xTitle = 'DateTime'; }
