CONVERT XMGRACE PDF
July 28, 2020 | by admin
“xmgrace” is a useful plotting package available with the linux operating system. “convert” is a generally useful linux command to change formats, e.g. you can. I want to save graph in jpeg format plotted using xmgrace software but there is no 2. in linux simply type “convert ” xx => format of your. I don’t think here is a direct export to pdf in xmgrace. You should print the file e.g. as postscript (File/Print_setup/Device and then File/Print), and convert it with.

Guide to the graphical user interface 4. Its strength lies in the fact that it combines the convenience of a graphical user interface with the power of a scripting language which enables it to do sophisticated calculations or perform automated tasks. From version number 4.
Grace User’s Guide (for Grace-5.1.22)
You can get the newest information about Grace and download the latest version at the Grace home page. The first version of Grace available is named 5. Though their License may by chance match the one used for Grace, the Grace Copyright holders can not influence or change them.
Grace usually compiles out of the box in xmyrace regular Unix-like environment.
Grace User’s Guide (for Grace)
If you want to compile your own changes to certain parts of Grace, you will need a parser generator yacc or, better, bison. Some features will be available only if additional libraries are installed. The PNG backend needs the libpng library version 0.
All transforms will be routed through this package. In short, this package allows one to do non-power-of-2 length FFT’s along with the normal ones.
The great feature here is that set lengths which are powers of 10 e. Very often, real datasets come in these sizes, and not in powers of 2. Decide whether you want to compile in a separate place thus leaving the source tree pristine. You most probably would want it if compiling Grace for more than one OS and keeping the sources in a central shared e. If you don’t need it, skip the rest of this paragraph and go right to the next step.
The configure shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create Make. It also create config. Finally, it creates a shell script config. If at some point config. If you change one of the –with-extra-incpath or –with-extra-ldpath options from one run of configure to another, remember to delete the config.
If something goes wrong, try to see if the problem has been described already in the Grace FAQ in the doc directory.
The later optional step will make soft links from some files under the Grace home directory to the system-wide default locations can be changed by the –prefix option during the configuration, see above. These are ordinary Grace projects, so you can play with them and modify them. Also, read the Tutorial. Here’s a VERY quick introduction: Start the GUI version: Acknowledge all changes with ‘Apply’.
To shift a data set by 20 to the left, e. Explore at your leisure. A project file contains all information necessary to restore a plot created by Grace, as well as some of preferences. Each plot is represented on a single page, but may have an unlimited number of graphs. A parameter file contains the detailed settings of your project.
Grace understands several input files formats. The data fields can be either numeric Fortran ‘d’ and ‘D’ exponent markers are also supported or alphanumeric with or without quotes.
Several calendar date formats are recognized automatically and you can specify your own reference for numeric date formats. Lines beginnig with ” ” are ignored. Blank lines indicate new dataset. Grace also has a command language see command interpreteryou can include commands in data files using lines having ” ” as their first non-blank character, though this is not recommended.
A graph consists of every element is optional: The graph type can be any of: The idea of “XY Chart” is to plot bars or symbols in general of several sets side by side, assuming the abscissas of all the sets are the same or subsets of the longest set. A dataset is a collection of points with x and y coordinates, up to four optional data values which, depending on the set type, can be displayed as error bars or like and one optional character string.
A set is a way of representing datasets. It consists of a pointer to a dataset plus a collection of parameters describing the visual appearance of the data like color, line dash pattern etc. Set type of num. Regions are sections of the graph defined by the interior or exterior of a polygon, or a half plane defined by a line. Regions are used to restrict data transformations to a geometric area occupied by region. Real Time Input refers to the ability Grace has to be fed in real time by an external program.
The Grace process spawned by the driver program is a full featured Grace process: The process will adapt itself to the incoming data rate. Hotlinks are sources containing varying data. Grace can be instructed a file or a pipe is a hotlink in which case it will provide specific commands to refresh the data on a mouse click a later version will probably allow automatic refresh.
Grace allows the user to choose between several output devices to produce its graphics. The current list of supported devices is:. Grace can also be instructed to launch conversion programs automatically based on file name. In many cases, when Grace needs to access a file given with a relative pathnameit searches for the file along the following path: Grace can access external functions present in either system or third-party shared libraries or modules specially compiled for use with it.
The term dynamic refers to the possibility Grace has to open the library at run time to find the code of the external function, there is no need to recompile Grace itself the functions already compiled in Grace are “statically linked”.
There are two types of coordinates in Grace: Points of data sets are defined in the world coordinates. The viewport coordinates correspond to the image of the plot drawn on the canvas or printed on, say, PS output page. The transformation converting the world coordinates into the viewport ones is determined by both the graph type and the axis scaling. Actually, there is yet another level in the hierarchy of coordinates – the device coordinates. However, you as a user of Grace should not worry about the latter.
The mapping between the viewport convrt and the device coordinates is always set in such a way that the origin of the xmgraec corresponds to the left bottom corner of the device page, the smallest of the device dimensions corresponds to one unit in the viewport coordinates. With respect to the user interface, there are three modes of operation that Grace can be invoked in.
The full-featured GUI-based version is called xmgrace. A batch-printing version is xmgrrace gracebat. A command-line interface mode is called grace. Usually, a single executable is called in all cases, with two of the three xmgace being symbolic links to a “real” one.
Form a set from the current block data set using the current set type from columns given in the argument. Assume data file is in netCDF format. This option is present only if the netCDF support was compiled in. Assume the answer is yes to all requests – if the operation would overwrite a file, Grace will do so without prompting. Run in the safe mode default – no file system modifications are allowd through the batch language.
This will be where help files, auxiliary programs, and examples are located. If you are unable to find the location of this directory, contact your system administrator. If the variable is xmgrwce but is an empty string, “Print to file” will be selected as default. The shell command to run an HTML viewer for on-line browsing of the help documents.
Upon start-up, Grace loads its init file, gracerc. The file is searched for in the magic path see magic path ; once found, the rest of the path is ignored. It’s recommended that conert the gracerc file, one doesn’t use statements which are part of a project file – such defaults, if needed, should be set in the default template see default template.
It’s recommended that in the default template, one doesn’t use statements which are NOT part of a project file – such defaults, if needed, concert be set in the gracerc see init file. If the rubber-banding for zooms and lines, etc.
You’ll need to derive the item’s X resource name from the respective menu label, which is easily done following these rules: All non-alphanumeric characters are skipped Start with lower case; each new word if any continues from the capital letter Add the item’s type to the end – “Menu” for pulldown menus, “Button” for menu buttons. Xresources file the file which is read when an X session starts; it could be. Xsession or some other file – ask your system administrator when in doubt. Similarly, it may be desirable to alter default filename patterns of file selection dialogs.
The recipe for the dialog’s name is like for menu buttons outlined above, with “Button” being replaced with “FSB”. Whenever the user is expected to provide a filename, xmgracw for reading in or writing some data, a file selection dialog is popped up.
In addition to the standard entries the directory and file lists and the filter entrythere is a pulldown menu for quick directory change to predefined locations the current working directory, user’s home directory and the file system root. Also, a “Set as cwd” button is there which allows to set any directory as you navigate through the directory tree as the current convrt directory cwd. Once defined, it can be used in any other file selection dialog to switch to that directory quickly.
Various selectors are available in several popups. They all display lists of objects graphs, sets,
