Is it possible to change point size in gnuplot

Question

How can I change the dot size in gnuplot. All of my searches show that I can use

plot .... with points <point_type> <point_size>

For example, with points 1 10 works fine. However there is no such option for with dots and it says it is not allowed here. Any suggestion?

Answer 1

Why do you want to change your dot size, when you can chose filled circles as symbols? Try this command:

plot ... with points pointtype 7 pointsize 5

Here

• pointtype (or pt) allows you to select different symbols (Each terminal has a default set of line and point types, which can be seen by using the command test, e.g. pngcairo: pt 5 would be a filled square)

• pointsize (or ps) allows you to control the size, as you had mentioned before.

I think the difference between a dot and a point is, that dot will always be a pixel-dot. If you are looking for more flexibility, points will allow that.
