ggsave exports graph that looks different from what is displayed in Rstudio

[Nicolas92]

I am generating a graph as follows:

chn_1 <- ggplot(gft_k_im[country == "CHN"], aes(x=imp_sha_2007, y=c_gft_k_2007)) + 
    geom_point(alpha=0.3, aes(size=imports_2007, color=continentb)) + 
    theme_ipsum(axis_title_size = 12) +
    labs(x="Import Share (in %)", y = "Change in GFT (in %)") +
    labs(size = "Imports (in bn.)", color = "Continent") +
    geom_smooth(method=lm,se=FALSE) + 
    geom_label_repel(aes(label = partner), 
                  max.overlaps = 70,
                  min.segment.length = 0,
                  box.padding   = 0.5, 
                  point.padding = 0.1,
                  segment.color = 'grey50')

The output looks as follows (which is what I want):

But when exporting the graph using ggsave the graph looks like this with more labels than I want:

ggsave("processed/graphs/chn_1.pdf", plot = chn_1, 
       device = cairo_pdf,
       width = 10, height = 6, dpi = 150)

Any idea why that happens? Sorry for not providing reprex. I'm not sure how to recreate that problem with toy data. Thanks!

You need to set the width , height and dpi such that the dimensions of the image produced by ggsave at least roughly matches those of the viewer image that you favour

You are absolutely right! Thanks for the hint, I had no clue that would be relevant.
