Fill Gap and Point Stylization Options

[JestersWorkshop]

I've been looking for options regarding fill gap line styles. Currently, the only style options are for line color which has been helpful in distinguishing datasets, but with this specific use case, there are often areas where data values are matched for prolonged periods and become more indiscernible. Adding line style options would be helpful even if that's just through line thickness. Options for dashed, dotted, or different repeated shapes would be really cool too. Differences in points per dataset would also be a helpful distinguishing factor (ie circle, triangle, square, star in the corresponding datasets color).

I've seen one other request for fill gap stylization regarding creating dashed lines for filling in empty data values which would also be a really useful addition.

The initial solution I had for distinguishing this specific data was to expand the aspect ratio to 3:1 vs the usual 1:1 which was really nice, but I'd really like to have a greater visual cue that lines are overlapping.

As a side note, the legend and title of the graphs are no longer centered when changing the aspect ratio. If you know a quick fix for that, I'd be super appreciative! Thanks for any help y'all
