How can I export a histogram without rasterising it? The labels and axes seem unaffected, but the bars themselves are pixelated when I zoom into them in a PDF viewer.
For example, if I run
Export["~/test.pdf", Histogram@RandomVariate[NormalDistribution, 1000]];
I get a PDF that looks like this when zoomed in:
This is a problem when I try to run it through
ps2pdf (to work around some font problems when including the PDFs in a LaTeX document), since the whole image gets rasterised, including the text.
