Dashed Lines

[dcjones]

Was #284, but GitHub wrongly thought I merged that.

Oh darn I just found this - so theres no real way to make plots for publication? Is there anyway to hack around this?

[dcjones]

It would be pretty easy to add an option to Theme that changes how lines are drawn, then you can use multiple layers if want dashed and non-dashed lines.

Trickier is to make a dashed aesthetic, since it would need to generate a unique pattern for an arbitrary number of categories.

I think Theme-per-layer would be great for me (I'm using layers rather than aesthetics). This might be a project on a scale I could handle.

oh just saw this. talking about the same in #455. @dcjones can i just ask, if the problem is that you want to create arbitrary different line types, i don't think it's necessary to have gazillions of those. I think ggplot gives you around 8 or so and then repeats. For most of what I need, two linetypes would be enough. It's really an issue if you want to use it for publication purposes. Some things change extremely slowly (like people printing papers).

@floswald Compose already has features to draw dotted lines, and you can specify the widths of the dashes and spaces to cycle through. So you can have arbitrary dotted line styles. It's a matter of giving it an API in Gadfly, I think.

Hey,

Yeah I've seen that in compose actually. Feeding it to gadfly is my
problem. I would have to spend some time figuring out how compose works.

Just curious... has there been any progress on different line styles?
