Plot an input file
Joachim Köppen DF3GJ ... Kiel, Aug 2016
Some brief explanations
- This utility plots the x-y data from a text file selected by the users
- The file must have this format:
- Each line contains one pair of x and y values, separated by blank space(s)
- Comment lines are ignored, if they begin with one of these four characters:
* # ' ;
- A maximum of 2000 data lines are displayed.
- When a file is loaded, the display ranges are automatically matched to the
data and both axes are shown in linear scales.
- When logarithmic scales are used, zero or negative range values are
not meaningful. Some protection against accidental occurrences is provided.
