I have a hopefully simple issue. I have a very basic pie chart that I need to export to pdf. This process is no problem, but the resulting pdf is of poor quality. There is what looks like partial grid lines and stray marks. Is this normal? This is what I am entering on the command line. FYI, I replaced the "greater than or equal to symbols" that I actually have for the lower limit with > for ease of pasting.
I am using Mathematica 8.0 on MacOS 10.11.6.
Export["uglypiechart.pdf",
PieChart3D[{9.69, 25.49, 21.36, 9.69, 1.80, 31.96},
ChartLegends -> {{"grade > A 9.7%" ,
"A > grade > B 25.4%",
"B > grade > C 21.4%",
"C > grade > D 9.7%",
"D > grade > E 1.8%",
"no grade 32%"}}, ChartStyle -> {"CandyColors"},
ChartLabels -> {"9.7", "25.4", "21.4", "9.7", "1.8", "32"}]]
