canvas is the total plotting area which appears when you run clplot.tcl frame is part of the canvas area. canvas is divided in n_row and n_column frames separated by n_gap pixels. graph is the result of plotting one data_set. data_sets may be in one file or in separate files. clplot.tcl is a tcl-tk script for 2-D and 3-D graphical displays of data, images and bitmaps based on tcl8.0.4 tk8.0.4 libraries and the patch file tk8.0.4dash.patch. It reads multiple sets of data stored in one or more files which may be plotted in one frame or in separate frames arranged in n_row and n_column. You can edit (select-cut-paste-move) any canvas-object (text-point-line-image-bitmap-window) as well as a canvas-frame. Canvas-objects and canvas-frames may be stored in the clipboard and restored anywhere on the canvas area or in a new canvas of another clplot.tcl application. To see the current bindings of the mouse buttons PRESS button (?) and select [bindings]. ***********************************************************************CONTENTS

*********************************************************************** clplot.inc: defines fonts-colors-images and some global variables. : it is read with a source statement in the program : clplot.tcl and in the subprocedure plotcomm. *.clplot : the file which initializes the parameters of graphs and : it has usually, but not necessarily, the extension : *.clplot is given as the first argument ($argv 0) : in calling clplot.tcl from a terminal or is : selected from the filemanager BOSS. If this file is : NOT given, then, the permanent file : $HOME/tcl-tk/graphics/input.clplot is read. : : the next second argument ($argv 1) which may be given : is the maximum number of graphs (max_graph) to be plotted. : : the third argument ($argv 2) is a list of filenames : (file_list) with the names of input data_file(s). : however you may select data_files after opening clplot; : see below. data_files: files which contain two columns of data (the (x,y) : coordinates). : sets of points which correspond to different graphs are : separated by an empty line. *.cobj : the extension of files where a whole graph is saved in : tk-form language. : this file is APPENDED every time you save : a graph (with the menubutton *Save*[GraphSave]). : if a file in the file_list has the extension *.cobj, : PRESS button R_COBJ if you want to read it. : clplot.tcl plots it and adds the data_file name in the : list of filenames (menubutton *Data*). : this option is used if you want to continue later on : interrupted work. *.canvas : the extension of files where everything on canvas : (many graphs) is stored in tk-form language. : this file is APPENDED every time you press the menubutton : *Save*[CanvasSave]. : if a file in the file_list has the extension *.canvas, : PRESS button R_COBJ if you want to read it. : clplot.tcl plots it, updates the value of the variable : max_graph and adds all the data_file names : in the list of filenames (menubutton *Data*). : this option is used if you want to continue later on : interrupted work. *.bobj : the extension of files where a selected area on the : canvas is saved in tk-form. This happens by using the : menubutton *Save*[BoxSave]. These files are created with : the canvas-edit facilities in the menubutton *EditC* and : are read by pressing button R_BOBJ. **************************************************************************** INPUT FILES AND HOW
TO CHANGE GRAPH'S PARAMETERS *****
*********************************************************************** ->->->->->-> You can call clplot.tcl from an xterm or from the file-manager BOSS where you can also select at the same time the input data_file(s): with NO arguments, e.g. $HOME/tcl-tk/graphs/clplot.tcl with ONE argument, the file which initializes the parameters of the graph, e.g. $HOME/tcl-tk/graphs/clplot.tcl input.clplot (or any other name with or not the extension .clplot) it is recommended to use one such file for each application. you then store in it possible changes of the parameters for future use when you want to replot the graphs with THREE arguments, the file *.clplot, the total number of selected files and a list with the names of the input data_files, e.g. $HOME/tcl-tk/graphs/clplot.tcl input.clplot $max_graph $file_list ! if you run clplot.tcl from BOSS you MUST give at least one argument.! ->->->->->-> if one or more selected files have the extension *.cobj, clplot reads them with the button *R_COBJ* and adds the input data_file(s) name(s) in the list of filenames (menubutton *Data*). this option is used if you want to continue interrupted work. ->->->->->-> if one selected file has the extension *.canvas, clplot reads it with the button *R_COB*, updates the value of the variable max_graph and adds all the data_file names used in the graphs in the list of filenames (menubutton *Data*). this option is used if you want to continue interrupted work. ->->->->->-> if one or more selected files have the extension *.bobj clplot reads them by pressing the button *R_BOBJ*. ->->->->->-> With the clplot.tcl widget on, you can add a new data_file name in the list of menubutton *Data*; (i) by typing its name in the entry widget (next to *Files* menubutton), this entry stores the name of the current data_file, variable $file; (ii) in the entry of the *I/O* widget and then selecting from the menu *Data_Var* the choice *current-files*; (iii) by using the browser *FileSelect* from the menu selection *Files*. After entering a new name of data_file in the entry widget press the menubutton *EditM* selection *add* to add it in the list of filenames (menubutton *Data*). You can delete the shown filename in the entry widget by the menu editor *EditM* selection [delete]. ->->->->->-> You can inspect the values of the parameters of a graph by pressing the appropriate menubutton of the *I/O* widget. To change the parameters of the graph FIRST put the new value in the entry of the *I/O* widget and THEN select from the menu the name of the parameter which is to be changed. This immediately changes the value and you can see the new parameter values by PRESSing again the *I/O* button. ->->->->->-> If you have data_files with multiple columns (x1,x2,...,y1,y2,...) use the unix command "awk" to select the two columns to be plotted. Select columns c1 and c2 transformed by the expressions f1 and f2 using the command "awk '{print c1^f1,c2^f2}' < input_file > (or >> to update an old file) output_file", where "^" is an arithmetic operation (+,-,*,/). ->->->->->-> You can plot contour plots by creating first (x,y) files for the contours by editing and running the program cont_surf_clplot.f which calls the routine contor. Similarly, you can plot 3-D graphs with dots or lines by running the program cont_surf_clplot.f which calls the subroutine purjoy. ->->->->->-> The bindings of the mouse buttons are defined from the menubutton *EditC*. The selection [CanvasEditBind] is for text-editing. The selection [CanvasBind] is for bindings on all graphical objects. The selection [CanvasBindDelete] erase all bindings. **************************************************************************** ENTRY WIDGETS *****
*********************************************************************** There are three entry widgets in CLPLOT.TCL One on the top-left which keeps the name of the current data_file (variable $file). Two at the bottom which keep the x- and y-coordinates of the current point in the coordinate space of the current frame. Thus, if you change frame you change the coordinates' origin in a multiframe plot. **************************************************************************** HOW TO PLOT *****
*********************************************************************** Step 1: CHOOSE the number of frames arranged in rows and columns and where to put the current graph. You can increase (+) or decrease (-) by one the number of rows and columns from the menubutton *Frames*. From the same menubutton you define the gap between successive frames. The frames are arranged in (i_row,i_column) order and the active frame is defined from the menubutton *Gfrm*. Step 2: CHOOSE the data_file to be plotted in the active frame from the menubutton *Data*. The name of the data_file appears on the entry widget on the left. You can edit the list of data_files from the menubutton *EditM* where you can [add] or [delete] data_file names. Step 3: PRESS button READ (or R_COBJ or R_BOBJ) to read the data_file and to transform the point to the canvas coordinate system if the file is in tk-form (for example those which have the extension *.cobj, *.canvas), then, PRESS button R_COBJ. Similarly for files *.bobj PRESS button R_BOBJ. Step 4: PRESS button Plot for a new plot button Overlay to put several data_files on the same plot and with fixed (xmin,xmax), (ymin,ymax). button Refresh replots periodically the current frame at every $rate milliseconds (ms). Remark: Steps 1 and 2 may be reversed. Remark: The ranges of the x- and y-axis, (xmin,xmax), (ymin,ymax), are adjusted every time a new data set is read from the same file or different files and the parameter xyminmax_fix is zero. They may be fixed to prespecified values by setting the parameter xyminmax_fix equal to 1. **************************************************************************** PARAMETERS (I/O WIDGET) *****
*********************************************************************** You can change the initial values of the graph parameters from these menubuttons. Use the power of the tk widgets by detouching the menu (clicking at the broken line) to have it in a permanent view. FIRST give the new value in the entry widget of *I/O* and THEN click on the appropriate menu the parameter you want to change. In this way YOU AVOID OF CREATING AND CLICKING ON MANY WINDOWS! To inspect the new values of the modified parameters you must press again the *I/O* button.//////// Font \\\\\\\ A new widget appears which shows all the fonts available in your system. The selected font is automatically stored in the entry widget of *I/O*. To change the previous font you either press the button *Font* on the Font widget or you select from the *Data_Var* menu in the *I/O* widget.//////// Color \\\\\\\ A new widget appears which shows the available named colors in your system. After selecting a color you may double click on it to see the color and store its name in the entry widget of *I/O*. Then, you click on the appropriate variable in the menubutton *Plot_Var* or *Frame_Var* on which the chosen color will apply.
