问题
I am trying plot data sets consisting of 3 coordinates: X-coordinate, x-coordinate and the number of occurrences. example:
1 2 10
3 1 2
3 2 1
I would like to draw for every line a dot at x,y with a diameter which is depending on the third value.
Is that possible with Gnuplot?
回答1:
Create a 2D plot with variable point size. See the demo.
Example:
plot 'dataFile.dat' u 1:2:3 w points lt 1 pt 10 ps variable
