Low quality PDF when exporting plot with 200.000 data points

As the topic states:
I plot the correlation of two vectors, each of dimension 200.000 x 1, which (naturally) gives a lot of data points. Now when I export the figure (using print) the quality of the resulting pdf is quite... poor. However, reducing the number of data points severely increases the quality so it has to be a resolution problem.

Using '-r500' as an example of changing the resolution and up, I dont see any big improvement in the quality, which is really irritating. I have tried increasing '-r' up to 1400 but it doesnt seem to do a whole lot for the overall quality.

Anyone has a solution?
