includes main-level program Horizons graph squeeze many line plots into a single graph by folding the
graph into bands and color coding them. The reduced vertical space allows
for more datasets to be compared and anomolies to be spotted more quickly.
They are based on the following description:

For example, this routine can produce the following plot:
topvis_horizon
vis_horizon, x, data [, titles=strarr(nseries)] [, nbands=long] [, minimum=numeric] [, maximum=numeric] [, ystyle=bitmask] [, colors=bytarr(nbands)] [, _extra=keywords]
Plot a horizon graph.
Parameters
- x in required type=fltarr(npoints)
x-values for all the datasets
- data in required type=fltarr(nseries, npoints)
datasets
Keywords
- titles in optional type=strarr(nseries)
y-axis titles for series
- nbands in optional type=long default=6
number of bands to break data into, must be even
- minimum in optional type=numeric default=min(data)
minimum value to use when dividing range into bands
- maximum in optional type=numeric default=max(data)
maximum value to use when dividing range into bands
- ystyle in optional type=bitmask
YSTYLE keyword to PLOT (YSTYLE=1 is automatically used)
- colors in optional type=bytarr(nbands)
colors to use
- _extra in optional type=keywords
