includes main-level programProduce a comparison chart as shown in the examples section.
Examples
See the main-level example program:
IDL> .run vis_comparison
It should produce output like:
Routines
result = vis_comparison_spread(values, charHeight, lineHeight)Spread out text lines that are too close to each other.
vis_comparison, names, startValues, endValues [, start_title=string] [, end_title=string] [, title=string] [, line_color=long] [, value_format=string] [, text_color=long] [, delimiter=string] [, _extra=keywords]Creates a comparison chart.
Routine details
top vis_comparison_spread
result = vis_comparison_spread(values, charHeight, lineHeight)
Spread out text lines that are too close to each other.
Return value
fltarr
Parameters
- values in required type=fltarr
values to spread
- charHeight in required type=float
height of a character in data coordinates
- lineHeight in required type=float
height of a line of text in data coordinates (baseline to baseline)
Other attributes
- Bugs:
this should probably be an iterative process because fixing up the values could actually cause more problems in certain cases
top vis_comparison
