Graduate Computing Workshop Day 4: Multiple Plots

Making Multiple Plots on the Same Page

Ordinarily the plot command erases the display before drawing the new graph. To draw multiple boxes and graphs on the same output page, use the command

	set multiplot

Any subsequent plot commands will then be overlaid on one another.

The following commands are commonly used in the multiplot environment.

set origin x,y: Set the origin (bottom left corner) of the next plot. The coordinate system used for x,y is such that the bottom left of the display is (0,0), and the top right is (1,1).
set size xscale,yscale: Set the size of the next box. if yscale is omitted, it is set to xscale. Scaling is relative to the standard box that almost fills the display.
set nomultiplot: Terminate the process of "accumulating" plots. The next plot command will erase the screen.

EXAMPLE:

	set multiplot
	set size 0.5
	set origin 0,0
	plot 'data1' every 3 using 1:3 with points
	set origin 0.4,0.5
	set size 0.4
	plot 'data2' lt 3
	set origin 0.6,0.1
	splot 'data4' every 5 lt 4
	set nomultiplot

Note that the prompt conveniently changes to

to remind you when you are in this mode.
