Hello Kiran,

 

I believe you need to specify $P{REPORT_PARAMETERS_MAP} parameter as a value of parametersMapExpression property for subreport. As of now it looks like startDate and endDate parameters in subreport have null values and your subreport query returns no data for the chart.

 

Also, a simple way to display two charts in a report would be to create a dataset and use it for the second chart instead of creating a subreport.
