SSRS - dynamic line style on line chart

Hi All,

I'm looking for a help how to dynamically set the line chart type (dotted, dashed etc). In my report I have cascading parameters reducing number of lines on one chart however if someone like to compare all the lines (about 20 on one chart), colors are becoming very similar and it's hard to determine based on Legend which is which. I though that I can make it more readable by distinguish them not only by color but also line type (green dashed, red DashDot etc).

Is there any way to make those styles dynamically assigned like colors?

Thanks for your help in advance,

Pawel
