plot lines        Plot lines from a document file.

 

inpt file: ASCII, white space separated columns.

REMARK: Since plotting has many different needs, the routine may change. Please 
        be not be surprized if these instructions are out-of-date.

USAGE:        plot lines

        .Input file: datafileascii001
        [Enter a file with the data you like to plot. This can be any ascii
         file with space separated columns. Since it is not special for 
         document files, please make sure you count the column correctly.
         Count also the column that indicates the number of values in a document
         file.]
        
        .Postscript file: plotpost001
        [Enter the name of the postscript file that should receive the
         plot. You can also add the .ps extension, which may be better
         for later easy printing.]
         
        .X-label test: absissa
        [Enter the text you would like to write to the X-axis. Default
         is simply X.]
        
        .Y-label text: ordinate
        [Enter the text you like to use to label the y-axis. Default is 
         Y.]
         
        .X-range (example 1:10): 1:100
        [Enter the range of the x-axis. This range is used to print the
         axis. Should be at least the range of the curve.]
         
        .Y-range (example 1:10): 0.1:0.8
        [Enter the range of the y-axis. Again this is used for the layout,
         not for the data. If the range is too short, the curve will be
         truncated.]
         
        .Font size multiplier: 2
        [If you want a larger or smaller font you can specify this here]
        
        .Number of curves in plot: 2
        [Enter the number of curves you like to plot onto the same sheet.]
        
For each curve it asks the following questions:
        .X-column, Y-column, Y-error: 1,2,3
        [Enter the data columns.The program treats a document file like any 
	 other file, i.e. that the key is column 1, register number column 2 
	 etc. If an error column is specified, the error is plotted as error
	 bars. This is at this time too dense, but still useful to get 
	 an idea.]
         
        .X-multiplier, Y-multiplier: 1.,1.
        [Specify a multiplier for the data. This is mostly interesting when
        curves of different ranges should be put on the same page.]

Example for plotting an FRC curve from a document file with 50 keys:

        plot lines
        frcdoc001       #Input file:
        nexttry003.ps   #Postscript file:
        Fourier radius  #X-label text:
        FRC     #Y-label text:
        0:0.5   #X-range (exampl 1:100): (here the absolute fourier radius is 
	                                  used)
        0:1.1   #Y-range (exampl 1:100): (the y-axis is left longer by 0.1 for 
	                                  better layout)
        1       #font size multiplier :
        2       #Number of curves in plot (def 1): (plots the FRC and the noise
	                                            curve)
        3,5     #X-column, Y-column, Y-error: (3 is the abs. radius column, 
	                                       5 the FRC column)
        1,1     #X-multiplier, Y-multiplier: 
        3,6     #X-column, Y-column, Y-error: (3 is the abs. radius column, 
	                                       6 the noise column) 
        1,1     #X-multiplier, Y-multiplier:
