g — Graphics

Screen plotting and display settings. For PostScript output and the PostScript language see Graphics & PostScript.

Plotting

Command	Action
`p`	Plot current spectrum
`pr`	Plot with new auto-ranges
`pn`	Plot next spectrum
`pv`	Plot previous spectrum
`a`	Add curve to current plot without clearing
`an`	Add next spectrum
`av`	Add previous spectrum

p replaces the current plot; a overlays on it. To plot data (file 0) and fit (file 1) together:

0,1 > p 1        # plot spectrum 1 of both files overlaid

Plot windows

Frida opens several windows at startup (linear-linear, linear-log, …).

Command	Action
`gw`	List all open plot windows
`g<n>`	Switch to window n

Axes and ranges

Command	Action
`gx <min> <max>`	Set x range
`gy <min> <max>`	Set y range
`ga`	Auto-range both axes
`gxa`	Auto-range x only
`gya`	Auto-range y only
`gxl`	Toggle log x scale (`gxl+` to enable, `gxl-` to disable)
`gyl`	Toggle log y scale
`gxf`	Toggle force-x-into-frame
`gyf`	Toggle force-y-into-frame

gxf / gyf — force into frame

When force-into-frame is on (default: off), Frida expands the axis range to include all data even if a manual range has been set with gx/gy. This prevents data from being silently clipped when you zoom in and then add a new spectrum that lies outside the current range.

Use gxf+ / gyf+ to enable permanently; gxf- / gyf- to disable.

Display options

Command	Action
`ge`	Toggle error bars (`ge+` to show, `ge-` to hide)
`gnd <n>`	Maximum number of data points plotted
`gnc <n>`	Number of equidistant base points for curve plotting
`gcr`	Toggle iterative refinement for curve plotting
`gsym`	Print a legend of plot symbols

gnc / gcr — curve plotting quality

When plotting a fit curve, Frida evaluates the curve expression on gnc equidistant points spanning the x range (default: a few hundred). If gcr is enabled, Frida then refines by adding extra evaluation points wherever the curve changes rapidly — useful for sharp peaks or steep edges. Increase gnc or enable gcr if a plotted curve looks jagged.

PostScript output

Command	Action
`gp`	Save complete PostScript file
`gd`	Graphic dialog — pass commands directly to gnuplot
