NAME
onegenplot - Make an X/Y plot with genhstplt
SYNOPSIS
onegenplot [options] data_file
DESCRIPTION
Onegenplot is a Python script to make Genhstplt draw one X/Y plot
then exit when its graph window is closed. It has many default set-
tings so that simple graphs can be viewed with a minimum of entries.
The data file is a text file with one or more columns of data values
for each individual item, separated by commas, spaces, or tabs. In
addition, the first entry for each item can be a type number or group
identifier. The file can have non-numeric lines at the beginning that
need to be skipped over. In most cases, this program can automatically
detect both the number of columns of data values and how many lines of
non-numeric text to skip at the beginning. See the -ncol and -skip
options for the limitations of this capability.
If there are no types in the file, you can graph one or more columns of
values versus one other column. If there are types, you can graph one
column versus another for one or more types. In addition, you use a
sequence of numbers instead of a data column for the X values, and thus
plot the sequential values of one or more columns or types.
Note that the graph window can be saved as a PNG file or printed from a
popup menu brought up by right-clicking in the window. For publica-
tion-quality graphs in Postscript, it is necessary to run Genhstplt
directly.
OPTIONS
Onegenplot uses the PIP package for input (see the manual page for
pip). Options can be specified either as command line arguments
(with the -) or one per line in a command file (without the -).
Options can be abbreviated to unique letters; the currently valid
abbreviations for short names are shown in parentheses.
-input (-i) OR -InputDataFile File name
Name of file with data to plot. If this option is not entered,
the first non-option argument is used for the name.
-ncol (-n) OR -NumberOfColumns Integer
The number of columns of data per item in the file, or 0 if the
number is in the file on a line just before the data, or -1 if
all the entries for a data item are on one line, so that the
number can be determined automatically. The default is -1.
-skip (-sk) OR -SkipLinesAtStart Integer
Number of lines to skip at the beginning of the data file. If
this option is not entered, the program will attempt to deter-
mine the number of lines to be ignored automatically. This
should work provided that any one of these conditions is the
case:
1) the extra lines always start with non-numeric text;
2) the number of numeric values at the beginning of extra
lines is fewer than the number of columns entered with -ncol
(minus 1 if -types is entered too);
3) extra lines start with a non-integer if -ncol is entered as
0;
4) extra lines start with only one number if -types is
entered.
-columns (-col) OR -ColumnsToPlot Multiple integers
Numbers of the columns to plot, numbered from 1. If more than
one number is entered and -ordinals is not entered, the first
number specifies the column to use for the X axis; otherwise all
numbers specify columns to plot on the Y axis. If there are no
data types, multiple columns can be given for the Y axis; if
there are data types, only one column can be listed for Y. If
this option is not entered, the default is 1 and 2, unless there
is only one data column or -ordinals is entered, in which case
the default is 1.
-types (-ty) OR -TypesToPlot Multiple integers
One or more data types to plot; types are not numbered from one
but correspond to the arbitrary type values in the data file.
With this entry, the first column of numbers in the file will be
read as type values, and the column after that will become the
first column of data. If there are type numbers in the file and
this entry is not given, the type numbers will end up in the
first column of data.
-symbols (-sy) OR -SymbolsForTypes Multiple integers
One or more symbols to use for the different types or columns
being plotted. Available symbol numbers are:
1, 2: Open and filled squares
3, 4: Open and filled diamonds
5, 6: Open and filled triangles
7, 8: X and +
9, 10: Open and filled circles
11, 12: Open and filled inverted triangles
13, 14: U and S
15: Open circle with vertical line
18: Small dot
19: Horizontal line
0: No symbol, points are automatically connected with lines
-1: Draw item number at each data point
If no, or not enough, symbol values are entered, the program
will assign symbols in order from this list: 9, 7, 5, 8, 13, 14,
1, 11, 3, 10, 6, 2, 12, 4, excluding any that have already been
specified.
-connect (-con) OR -ConnectWithLines
Draw lines between successive points within a type or column;
this entry is not needed if the symbol is 0
-ordinal (-o) OR -OrdinalsForXvalues
Plot data within each column or type sequentially in X, i.e.,
versus a set up numbers that start from 1 and increase by 1 for
each value plotted. This entry is implied if only one column is
entered.
-xlog (-xl) OR -XLogOrRootAndBase Two floats
1 to take the logarithm or 2 to take the square root of X val-
ues, and the base to add before that operation. A base is
needed to avoid taking the logarithm or quare root of negative
numbers. An appropriate base value can also be helpful for
spreading out the data more evenly. The numeric axis labels on
the graph will be in the units of the data after the operation,
e.g., in log units, not in original units.
-ylog (-yl) OR -YLogOrRootAndBase Two floats
1 to take the logarithm or 2 to take the square root of Y val-
ues, and the base to add before that operation.
-hue (-hu) OR -HueOfGroup Text string
This option can be used to specify a color for each group being
plotted. Groups are numbered from 1 and correspond to the types
or columns being plotted in separate curves. Enter either 4
integers separated by commas (the group number and the red,
green, and blue values, ranging from 0 to 255) or the group num-
ber and a stock color name separated by a comma. Groups without
a color will be drawn in black. (Successive entries accumulate)
-defhue (-d) OR -DefaultHues
Assign default colors for all groups without a specific hue
entry. The default colors are a subset of 12, including black,
that are chosen from the stock colors for their distinguishabil-
ity. Each group without a color specified by -hue will be
assigned one of these default colors, with the colors used in
order and cycled through again if more than 12 are needed.
-stock (-st) OR -StockColorList
List standard colors available by name in the -hue option.
These are a subset of standard HTML color names and values.
-axis (-a) OR -XaxisLabel Text string
Label for the X axis
-keys (-k) OR -KeyLabels Text string
Text to display as a key for one type or column, shown along
with that type's or column's symbol, if any, on the right side
of the window. Text is drawn in a large box with word wrapping
enabled, so the key can be longer than the space on the right of
the graph. The program will show default keys with the column
or type number if not enough labels are entered. (Successive
entries accumulate)
-message (-m) OR -MessageBoxLine Text string
One line of a message to be displayed in a message box (Succes-
sive entries accumulate)
-tooltip (-to) OR -ToolTipLine Text string
One line of tooltip for the graphics window (Successive entries
accumulate)
-size (-si) OR -SizeOfPlot Two integers
Size of graphics window in X and Y, in pixels
-position (-po) OR -PositionOfPlot Two integers
Coordinates of the top left corner of the graphics window in X
and Y, in pixels, where Y is 0 at the top of the screen.
-xminmax (-xm) OR -XRangeMinAndMax Two floats
Lower and upper limit of X range for graph. If the limits do
not define a range that is a multiple of one of the allowed fac-
tors, the range will be rounded up.
-yminmax (-ym) OR -YRangeMinAndMax Two floats
Lower and upper limit of Y range for graph
-png (-pn) OR -SavePNGandExit File name
Save the graph as a PNG to the given file name (which should
include its extension), close the graph window, and exit the
program.
-remove (-r) OR -RemoveDataFile
Delete input file when exiting. This option is meant to be used
only when running in the background, as cleanup will not occur
if the program is interrupted with Ctrl-C.
-help (-he) OR -usage
Print help output
-StandardInput
Read parameter entries from standard input
EXAMPLES
If the data file has 2 or more columns,
onegenplot data_file
will plot the second column versus the first, showing scattered open
circles.
If the data file has at least 5 columns,
onegenplt -col 1,3,5 -con data_file
will plot column and 3 and 5 versus column 1, with circles and X's,
respectively, connected by lines.
If the data file has type numbers 10, 20, 30, and 40 and at least 5
data columns,
onegenplt -col 2,4 -type 20,40 -sym 10,9 data_file
will plot column 4 versus column 2 for types 20 and 40 with closed and
open circles, respectively.
If the data file has has 120 lines of data in 6 columns,
onegenplt -col 3,6 -sym 0,0 -con -ord data_file
will plot columns 3 and 6 sequentially versus 1 to 120 with lines and
no symbols.
