I have recently installed gnuplot on my mac and I am having troubles in managing the curves options correctly:
- the default colours are completely mismatched
- the dashed or dotted commands seem not to respond (thickness works fine though)
- this happens also for the mesh of the surface 3d plots (colours of the surface are OK though)
- the problem persists using different terminals (I mainly use X11) and so different output files (I need eps)
This is a basic example of what I get (I am now allowed to upload image, sorry):
plot sin(x) lc 1 lw 3 lt 3
I get the wrong colour of curve: the curve should be red while it shows purple
