Frida produces two kinds of graphical output:

• Screen display via Gnuplot — interactive, for exploration
• PostScript files — for publication-quality, hand-editable figures

Screen plotting

Command	Effect
p	Plot the current selection
pr	Plot with fresh auto-ranges
pn / pv	Plot next / previous spectrum
a	Add to the current plot
an / av	Add next / previous spectrum
gw	List all plot windows
g<n>	Switch to window n
ga	Auto-range both axes
gx <lo> <hi>	Set x range
gy <lo> <hi>	Set y range
gxl / gyl	Toggle log scale on x / y
ge	Toggle error bars

Frida opens several plot windows by default (linear-linear, linear-log, …). Use gw to list them and g<n> to switch.
