How to draw lines for specific parameter on feature layer of map chart using Tibco spotfire?

I am populating maps on feature layer of map chart. In the map area i have seggregated parameters with specific color. Now i am trying to add lines(backslash lines) for some parameter. In order to differentiate properly. Some areas of maps will be noted by color and some area will be noted by lines on top of color.

Is there any way to get this done?I am adding image for your reference.
