Parameters

This section documents the parameters recognized by this task (if any).

Parameter	Mand	Type	Default	Constraints
withtable	no	boolean	true	true$\vert$false
If set to true a table with numerical data column to be plotted is provided via parameter table
table	no	table		name of existing table
The table to be plotted in set:table notation (where set is typically a FITS file).
title	no	string
Title for the plot - if none is given the table name shall be used.
subtitle	no	string
Subtitle for the plot.
withx	no	boolean	false	true$\vert$false
If true, the user-specified x column is used for the horizontal axis. If set to false and index is likewise false the first numerical column in the table will be taken as the $x$ axis.
x	no	column		name of existing column
The name of the column to be used for the $x$ axis.
withoffsetx	no	boolean	false	true$\vert$false
If set to true all $x$ values are offset by the negative of the first $x$ data value, hence, the $x$-axis starts at 0. This is useful for plotting time series when the time tag values are large in magnitude.
offsetx	no	real	0.
$x$-axis offset value (output).
index	no	boolean	false	true$\vert$false
Whether to use the index (0,1,2 ...) for $x$ instead of a column.
withxmin	no	boolean	false	true$\vert$false
If true xmin is set.
xmin	no	real	0.
Lower bound of x axis to show in plot.
withxmax	no	boolean	false	true$\vert$false
If true xmax is set.
xmax	no	real	0.
Upper bound of x axis to show in plot.
xlog	no	boolean	false	true$\vert$false
If true x axis is produced with logarithmic scaling.
withy	no	boolean	false	true$\vert$false
If true, a curve is produced only for the y column that are specified in the y parameter. Otherwise all numerical columns in the table shall be plotted.
y	no	list of compound column identifiers
A compound column identifier takes the form: colname|colname.errcolname|colname.errcolname.errcolname where colname can simply be the name of a numeric column in the input table or be of the form: colname[from,to,incr] which expands into the list of vectors columns starting from row from to row to in steps of incr. incr and to are optional. If incr is omitted it is taken as 1 and a missing to default to the value of from, hence, only the vector in row from is plotted. If a vector column is specified just by its name only the first row is considered. errcolname can be the name of a numeric column which will be displayed in the form of an error bar in $Y$- (colname.errcolname) or $X$+$Y$- (colname.errcolname.errcolname) direction. errcolname can also be given as a vector column with a single row specifier in square brackets.
withymin	no	boolean	false	true$\vert$false
If true ymin is set.
ymin	no	real	0.
Lower bound of $y$ axis to show in plot.
withymax	no	boolean	false	true$\vert$false
If true ymax is set.
ymax	no	real	0.
Upper bound of $y$ axis to show in plot.
ylog	no	boolean	false	true$\vert$false
If true y axis is produced with logarithmic scaling.
withscatter	no	boolean	false	true$\vert$false
If set to true the data is presented as a 2-D scatter plot where each data item is marked by a symbol (default +).
setsymbols	no	list of integers		symbol IDs in Grace
If withscatter is set to true the data points of curve $i$ will be marked with a symbol of ID setsymbols[i]. See the Grace documentation for the list of available symbols IDs.
setcolors	no	list of integers		color IDs in Grace
If withscatter is set to true the data points of curve $i$ will be marked with a symbol of color setcolors[i]. See the Grace documentation for the list of available color IDs.
withxranges	no	boolean	false	true$\vert$false
If set to true the parameter xrangetables must contain a list of tables with column data that define finite abscissa ranges that are to be displayed.
xrangetables	no	table list		list of existing tables
If withxranges is set to true this parameter must contain a list of tables with data to be plotted as horizontal abscissa data ranges. For each provided table a separate horizontal line of range markers shall be plotted - the vertical position of the lines will be ybase$+ n\cdot$ystride with $n$ ranging from 0 to $N-1$. 0 and $N-1$ corresponds to the data in the first and last table given in xrangetables respectively.
withalltablesafter	no	boolean	false	true$\vert$false
This parameter facilitates the plotting of a large number of abscissa range data in consecutive tables in a named data set (e.g. a sequence of Good-Time-Interval tables as generated by hkgtigen's diagnostic mode). When set to true xrangetables is supposed to contain a single table name and all tables positioned after this table shall be considered as containing abscissa range data to be plotted.
xrangefromcol	no	column	START	existing column in all xrangetables
The name of the column in all tables given in xrangetables containing the values of the left boundaries of the abscissa range markers.
xrangetocol	no	column	STOP	existing column in all xrangetables
The name of the column in all tables given in xrangetables containing the values of the right boundaries of the abscissa range markers.
withybase	no	boolean	false	true$\vert$false
If set to true ybase is given.
ybase	no	real	0.
The vertical position of the first abscissa marker line corresponding to the first table in xrangetables. If not explicitly given a default value based on the actual vertical extent of the plot shall be used.
withystride	no	boolean	false	true$\vert$false
If set to true ystride is given.
ystride	no	real	0.1
The vertical distance between adjacent abscissa range marker lines in world coordinates of the plot. If not explicitly given a default value based on the actual vertical extent of the plot shall be used.
output	no	stdout|file	stdout
destination of output
outputfile	no	string	plot.dat
the name of the output file if output is set to file
