sfwiggle plots data using the traditional seismic method of wiggly traces.
The following example from rsf/rsf/rsftour shows a typical output:
Similarly to other plotting programs, there are multiple parameters that control the output. For example, poly=y draws solid polygons for highlighting positive data, transp=y transposes the two axes, xreverse=y or yreverse=y reverse the corresponding axis. Data scaling is controlled with either the absolute clip (clip=) or percentage clip (pclip=).
The following example uses transp=y poly=y yreverse=y pclip=100 unit2=km unit1=s label1=Time label2=Offset:
Use seemean=y to display lines corresponding to the mean value, use zplot= to control relative separation between different traces (the default is 0.75). The following example from bei/sg/toldi uses zplot=0.4:
Finally, sfwiggle makes it possible to plot irregularly sampled data by providing trace coordinates in xpos= file and (optionally) coordinate range with xmin= and xmax=. The following example from jsg/avo/avo2 shows a seismic gather displayed with (a) sfgrey in trace-number coordinates and (b) sfwiggle in offset coordinates.
