Hi all, so I commited the change to the cairo driver by adding a new function filled_polygon(). You can play around with the width of the stroke by changing this line: cairo_set_line_width(aStream->cairoContext, 1.0); A width of 1.0 is good for shade plots without transparency. Example 30 does

Alan, One other thing it would be nice to finalise before a release is what we are going to do with the date / time handling. I know there was a lot of discussion about this but we never came to a firm conclusion. If it doesn't make it into the next development release then fair enough, but we re
