I am using a GradientTheme to represent information on a polyline. I have everything working except for one caveat. There are certain situations where I do not have data for a section of the line. What can I set the variable to so that the Theme will render
the line using a preset style that is used to represent no data? I.e. set the colour to be grey rather than the Rainbow5 theme. Is this possible with the standard class or will I need to subclass?
