No grid lines inside the panel, but axis ticks are present in Gadfly - Julia

So, basically I want to make a graph that shows the axis ticking a small line, but does not display grid lines inside the panel.

I was able to hide the grid lines inside the panel with Theme(grid_line_width=0mm)

and add a border with panel_stroke=color("black")

.

It looks like this:

which is close enough to what I'm looking for, except that I need small ticks for the axes.

I tried with

Guide.xticks(ticks=[0:50:500]),
Guide.yticks(ticks=[0:0.001:0.007])

      

        
        
        
      

    

no luck.

Any ideas?
