When I use the Dashed
option in my 3D parametric plot, the dashing looks very muddy and the dashes are running together. For example, I plot the below code, right click and Save Graphic As...
to pdf. Notice the dashed lines running together in different parts of the plot.
ParametricPlot3D[{l, l, l^2}, {l, 0, 20}, PlotStyle -> {Red, Dashed},
PlotRange -> {{0, 10}, {0, 10}, {0, 20}}, Boxed -> False, AxesOrigin -> {0, 0, 0}]
How can I fix this? I'm currently using Mathematica 9, not sure if this is still a problem in Mathematica 10.
