@scriptzguru,
may I know how to convert 2018-10-04 to 02T11 format ?
You can use valueFormatString to format x-values along axisX and xValueFormatString to format x-values in indexLabel or toolTip according to your requirement.
and I want multiple line chart on this , is it possible ?
Yes. Please refer to our documentation rendering multi-series charts.
