QUICKPLOT(1) General Commands Manual QUICKPLOT(1)

NAME

quickplot - a fast interactive 2D plotter

SYNOPSIS

quickplot [OPTIONS]

DESCRIPTION

Quickplot is an interactive 2D plotter. It's primary focus is to interactively display 2D plots. It can generate PNG image files. Quickplot has a graphical user interface, lots of command line options, and a command line shell interface as well. Quickplot can load ASCII text files and many sound file formats using the libsndfile library. Quickplot can read standard input as a pipe or regular file.

The full documentation for Quickplot is maintained as a HTML document in a file named help.html. You can get the latest version at <http://quickplot.sourceforge.net/help.html>. The options part in this man page is generated from the same source as the options part of the HTML document.

The order of argument options matters. Options take effect in the order that they are given with later options overriding earlier ones. The options that cause actions like graph "something" must come after the option that says to read the file that has "something" in it. In general, the order of argument options gives the order in which things happen as Quickplot starts up.

OPTIONS

read data from file FILE. If FILE is - (dash) then standard input will be read. This is the same as the --file option. See also --pipe.
display introductory information about Quickplot in a browser and exit
automatically select the X and Y scales for graphs containing more than one plot. This is the default. See also --same-x-scale, --same-y-scale, --same-scale --different-scale.
set the color of the graph background. RGBA may be any string that GTK+ can parse into a RGB or RGBA color. For examples --background-color='rgba(0,0,255,0.5)' will make translucent blue, and -C '#050' will make a dark green.
add a border to main window. This is the default. See also --no-border.
show the button bar in the main window. This is the default. See also --no-buttons.
draw graphs using the Cairo API. Cairo drawing may be slower, but you get translucent colors and anti-aliasing in all aspects of the graph and in saved image files. See also --x11-draw.
create the default graph for the current file and turn default graphing for future files read. If you give a --graph or --graph-file after this option you will generate an additional graph. A default graph will be made each time this option is encountered, so this can be used to control when, in the sequence of command line options, graphs are made. See also --no-default-graph.
graphs with more than one plot will have different scales if the extreme values in each plot are not all the same. See also --same-scale, --same-x-scale and --same-y-scale.
read data from file FILE. If FILE is - (dash) then standard input will be read. See also --pipe.
make the main window fullscreen. See also --no-fullscreen and --maximize.
interpret NAN, -NAN, INF, -INF, and double overflow numbers as a gap in the plot, and don't draw a connecting line to adjacent non-gap points. This is the default. See also --no-gaps.
specify the position and size of the main window. To set the geometry back to the default just set GEO to NONE. Example --geometry=1000x300-0+30
make a graph with plots LIST. The LIST is of the form "x0 y0 x1 y1 x2 y2 ...". For example: --graph "0 1 3 4" will make two plots in a graph. It will plot channel 1 vs channel 0 and channel 4 vs channel 3 in the same graph. Data channels are numbered, starting at 0, in the order that they are created as files are read. A separate graph tab will be created for each --graph option given. This --graph option must be after the file loading options that load the channels that it lists to plot. See also --graph-file.
make a graph with plots LIST. The LIST is of the form "x0 y0 x1 y1 x2 y2 ...". Example: --graph-file "0 1 3 4" will make two plots in a graph. It will plot channel 1 vs channel 0 and channel 4 vs channel 3 in the same graph. A separate graph tab will be created for each --graph-file option given. This is like the --graph option except that the channel numbers start at zero for the last file read. They are relative channel numbers. So channel numbers for ---graph-file may be negative to refer to channels that came from files before the last file. This is handy if you load a lots of files and lose count of the number of channels loaded in each file.
draw a grid with the graph. This is the default. See also --no-grid.
set the font used to in the grid label numbers. Example: --grid-font='Sans Bold 12'. The default grid font is "Sans 10".
set the graph grid lines color. RGBA may be any string that GTK+ can parse into a RGB or RGBA color. For example --grid_line_color='rgba(255,0,0,0.5)' will make a translucent red.
set the width of the grid lines if there are any
show grid numbers. This is the default. The grid must be showing to show grid numbers too. See also --no-grid-numbers.
set the graph grid text color. RGBA may be any string that GTK+ can parse into a RGB or RGBA color. For example --grid_text_color='rgba(0,255,0,0.5)' will make translucent green.
set the maximum x space between vertical grid lines. The minimum will be about half this. This distance varies as the scale changes due to zooming. This distance cannot be fixed due to the way Quickplot scales your graphs and always picks reasonable grid line spacing. See also --grid-x-space.
set the maximum y space between horizontal grid lines. See also --grid-x-space above.
print the version of GTK+ that Quickplot was built with and then exit
show the menu bar, button bar, tabs bar, and the status bar. This is the default. See also --no-gui.
display help in a browser and exit
specifies the label separator string STR if labels are read in from the top of a text data plot file. The default value of STR is " " (a single space). See option: --labels.
read labels from the first line of a text file that is not skipped. See also: --skip-lines, --label-separator and --no-labels.
print the version of libsndfile that Quickplot was built with and then exit
specify the plot line widths in pixels. May be set to AUTO to let Quickplot select the line width based on the plot point density. AUTO is the default.
OPTS are START|[STEP]. This option prepends a linear series channel to the file being read.

START set the first value in the sequence to START. The default START value is 0.

STEP set the sequence step size to STEP. The default STEP is 1. There must be a START before STEP. For example: --linear-channel='100 0.2' will make a linear channel that starts at 100 and steps 0.2. Sound files will always have a linear channel that contains the time prepended. Using this option with a sound file would prepend an additional channel. Any file loaded that contains just a single channel will automatically have a channel prepended. Using this option with a single channel file will not prepend an additional channel, but will let you set the start and step values for that prepended channel. See also --no-linear-channel.

Y yes show lines.

N no don't show lines. Same as --no-lines.

A auto, be smart about it. This is the default.

disable that darn Ubuntu Unity globel menu bar. This will do nothing if not running with Unity.
maximize the main window. See also --no-maximize and --fullscreen.
show the menu bar. This is the default. See also --no-menubar. This will do nothing if not running with the Ubuntu Unity window manager.
make a new main window for each graph
display graphs main windows with no borders
hide the button bar in the main window. See also --buttons.
stop making the default graph for each file loaded. See also --default-graph.
don't make the main window fullscreen. This is the default. See also --fullscreen.
draw a line across NAN (-NAN, INF, -INF and overflow double) values if there are finite values on both sides. See also --gaps.
don't draw graph grid lines in the graph. See also --grid.
don't show grid numbers. See also --grid-numbers.
don't show the menu bar, button bar, tabs bar, and status bar. See also --gui.
don't read channel labels from the file. This is the default. See also --labels.
turn off adding a linear channel for up coming files. See also --linear-channel.
plot without drawing lines in the graph. See also --lines.
don't maximize the main window. This is the default. See also --maximize.
don't display the menu bar in the main window. See also --menubar. This will do nothing if not running with the Ubuntu Unity window manager.
don't make a new main window for the graph. This is the default. See also --new-window.
don't read data in from standard input even if there is input to read. See also --pipe.
plot without drawing points in the graph. See also --points.
don't use GNU readline with the Quickplot command shell if you run with the --shell option. This will disable the use of line editing, shell history, and tab command completion. This option has no effect if Quickplot is not built with GNU readline.
turn off the use of the X11 shape extension. See also --shape.
hide the status bar in the main window. See also --statusbar.
don't show the graph tabs in the main window. See also --tabs.
set the default maximum number of plots for each graph to NUM
read graph data from standard input. By default Quickplot looks for data from standard input and stops looking if no data is found in some short amount of time. This option will cause Quickplot to wait for standard input indefinitely. If you would like to type data in from the terminal use --pipe. This option is the same as --file=-.
start Quickplot using plot point size PIXELS wide in pixels. This may be set to AUTO to have quickplot automatically set the point size depending on the point density that is in graph. AUTO is the default.
show points in the plots in the graph. This is the default.
prints the About document to standard output andthen exits. Use option --about to display an HTML version of the Quickplot About information.
prints this Help document as ASCII text to standard output and then exits. Use option --help for displaying an HTML version of this help.
this is a place holder that tells Quickplot when to read the data from standard input. This is intended to give the option of telling Quickplot when to read standard input when Quickplot automatically determines whether to read standard input or not. See options --file, --pipe and --no-pipe.
plot all plots in the same graph scale. See also --different-scale, --same-x-scale and --same-y-scale.
use in place of --same-scale or --auto-scale for finer control over how the x values of the plots are scaled when you have more than one plot on a graph

Y yes same x scale

N no different x scales

A auto, be smart about it. This is the default. See also --same-y-scale.

use in place of --same-scale or --auto-scale for finer control over how the x values of the plots are scaled when you have more than one plot on a graph

Y yes same y scale

N no different y scales

A auto, be smart about it. This is the default. See also --same-x-scale.

make graphs see through. It uses the X11 shape extension which was made famous by xeyes. The X11 shape extension may be a little flashy on some systems. Try using --shape with the --no-gui, --no-grid, and --no-border options to make a floating graph on your display. The use of the X11 shape extension is a property of the main window, not each graph tab. This option may not work well with fullscreen view. This will slow down graph drawing considerably. You can toggle this on and off with the x key. See option --no-shape.
run a Quickplot command shell that reads commands from standard input and writes out to standard output. The default is no shell and standard input will be read as graph data. If Quickplot is reading standard input for plot data Quickplot will read shell commands from the controlling terminal (/dev/tty) after all the standard input has been read. You may use --no-pipe to stop standard input from being read as graph data. The shell can do most all the things that command-line options can do and a lot more. Run an interactive shell with quickplot --shell and use the help and tab completion to see how it works. You can also connect a Quickplot command shell to a running Quickplot program with the program quickplot_shell.
signal SIGUSR1 to process PID after Quickplot is running.
don't spew even on error. The --silent option will override the effect of the --verbose option.
skip the first NUM lines when reading the file. This applies of all types of files that quickplot can read. Set NUM to zero to stop skipping lines.
show the status bar below the graph. This is the default. See also --no-statusbar.
show the graph tabs. This is the default. See also --no-tabs.
spew more to standard output. See also --silent.
print the Quickplot version number and then exit returning 0 exit status
draw points and lines using the X11 API. This is the default. Drawing may be much faster than with Cairo, but there will be no translucent colors and no anti-aliasing in the drawing of the plot lines and points. There will be translucent colors and anti-aliasing in the background and grid. Also, saved images will not have translucent colors like they do with the Cairo draw mode. You can start drawing with X11 and switch to drawing with Cairo when you want to save an image. Use the r key or the View menu to switch back and forth between drawing with X11 and Cairo. See also --cairo-draw.
