How can I avoid “line breaking up” with line chart-JasperReport?

I am using Jaspersoft Studio version 6.3.0.final with JasperReports Library version 6.3.0 . I'm creating a Line chart with different series and category values. My question is that, when the graph is plotted, I observed that if for one category there are no values for a particular series, the line breaks and the line starts again from the next data point.

Is there anyway in which we can connect ALL the points in a particular series, so that it will be one continuous single line instead of broken lines and dots ?
