I need to make a contour plot for publication, but even if I set ContourStyle->Black
, the 'black' plots and the axes are very faint. When I export the figure in svg and open it in some image-processing software (inkscape), the colour shown for the selected plot is actually a 'gray' colour instead of 'black' in rgb scale.
As shown in the figure, it is obvious the dashed line is a lot darker than the gridlines and tick markers. How to make the Gridlines, the tick markers and everything appear darker (not thicker, I am happy with the current thickness)?
ContourStyle -> Directive[Black, Opacity[1]]
help? $\endgroup$Opacity
andGrayLevel
does help. Thanks. But that only applies to the contour lines and still I don't know how I can make the tick markers (2, pi, pi/2, etc) darker $\endgroup$..., FrameStyle -> Black]
should drive frame components, including tick marks, toBlack
. $\endgroup$FrameStyle->Black
does make it work. thanks! $\endgroup$
