How to shows the axis ticks little line?

[ehdiix]

So, basically I want to make plot that shows the axis ticks little line but doesn't show the grid lines inside the panel. Is it possible?

wow, what an omission.

i was hoping grid_color or grid_line_width in Theme could be used as a hack, but those both effect the axis ticks as well.

relevant code is here.

need to think about the user interface. perhaps adding a boolean grid keyword argument to Guide.{x,y}ticks.

I encountered same problem recently.
I used the following code to make a plot that has a border and no grids inside the polt, which is quite common in a lot of academic papers. However, I don't know how to add ticks on the x-axis and y-axis without having grids. Is this possible? If not, will it be added as a feature in the future? I think it would be a useful one. Thank you!

using Compose, DataFrames, Gadfly, RDatasets
D = dataset("datasets", "iris")
p = plot(D, 
              x=:SepalLength, y=:SepalWidth, 
              color=:Species, 
              Theme(panel_stroke=colorant"black", 
                          grid_line_width=0mm))

Adding tick marks is not on my current Roadmap #1385, but there is PR #792 which appears abandoned, so someone could modify/update.

For what it's worth, I would also find this very helpful

@frankwswang
Thanks for the solution but,
I do not need the upper and right panel stroke.
Is it possible?

[frankwswang]

I don't know how to resolve that issue. Sorry!
