time series data in milliseconds

[Kevin-Bobby]

How do I add time series data in milliseconds, it works when I add data every second, if i add it once every half second the two data overlaps in the same place, is there anyway to update the time axis once every few milliseconds. I set xAxis.type = Axis.AxisType.Time; if i change to value axis im not able to add xaxis label it automatically adds values to it. And i cant do it as category axis. please help
