To modify the borders of the polygons use the following instructions:
- On the Marks card, click Color.
- Under Effects, select the Border drop-down, select border color desired.
Hope this helps!
Thanks for the response. While that is the way to colour the boundaries, the issue I'm having is that it colours the boundaries of all the polygons within the SHP file. I need to set different colours for different polygons but the way specified only sets the colour for all.
