Saving contourplot with high quality

Question

I have plotted a colored figure using contourplot. What is the best way to save it so that its quality becomes higher? I want it use in Latex.

Export["fig.pdf", plot]; or with .eps if you prefer. – corey979 Jan 16 '17 at 14:02 — corey979, Jan 16 '17 at 14:02

If you use pdflatex, I recommend:

Use Export instead of Save Graphics As.

plot = ContourPlot[x^2 + y^2, {x, -1, 1}, {y, -1, 1}]

First try

Export["plot.pdf", plot]

If the result is not acceptable, try

Export["plot.png", plot, ImageResolution -> 4*72]

The default image resolution is 72 dpi. Use 4*72 to get a four times larger image. Find the correct size for your needs.
