Programs display, displaybubbles, displaycontour, displaytext and show - graphical display of any xy data such as magnetisation etc.

display 1 11 ./results/mcphas.fum

produces a graphical display of the data file mcphas.fum on screen. The display contains an xy plot of column 1 versus column 11 (java has to be installed to use this program). More files may be displayed by commands such as

display 1 2 data1.dat 3 5 data2.dat.

Note that viewing of data which is generated by programs may be viewed online. The program updates the plot every 500 milliseconds. In this way it is possible to watch online, how programs calculate data. The output of display may contain lines to tune the display output, such as

	most general usage: 

 display [-options] xcol[excolerr] ycol[eycolerr][bcolbubble] filename [xcol1[] ycol1[] filename1 ...]

         xcol,ycol ... column to be taken as x-, y- axis in a lineplot, expressions such as 'c1xc2+1' are allowed
	 filename ..... filename of datafile
	 Data files may contain lines to tune the display output, such as
	 # displaytitle=My new Graph
	 # displayytext=intensity
	 # displayxtext=meV 
         if optional errorcolumns are added then instead of lines symbols and errorbars are shown
	 if optional bubblecolumns are added then instead of lines bubbles with area corresponding to
	     bubblecolumn are shown (toggle bubblesize with 's' and 'b')
	 toggle lines / points view with '-' key
         
       options:  -o file.jpg  create a jpg file on exiting, also create file.jpg.gnu to be used in gnuplot
                 -c file.jpg  only creates a jpg file and exit immediately, also create file.jpg.gnu 
                 -logx -logy  make x(y) a logarithmic axis
                 -xmin 23.3 the application sets the minimum of the display xaxis to 23.3
                 -xmax -ymin -ymax -xtext -ytext -title ...similar
                 -vlines 2|(201),3.4,12.3 shows vertical lines at specified x values
                          a text to be written as line label can be added by inserting | and adding the text
                 -hlines 2,3.4,12.3 shows horizontal lines at specified y values
                 -g shows gridlines
                 -dim 400 200  set dimension of plot (in pixels width 400 height 200)

displaybubbles 5 6 8 ./results/mcdisp.qei

works similar as display, however a third column is given and the radius of the symbols varied according to the data in this column.

displaycontour 5 6 8 ./results/mcdisp.dsigma.tot

produces a graphical display of a 3 dimensional dataset as a colour and/or contour plot. Here '5 6 8' denote the x,y and z column in file ./results/mcdisp.dsigma.tot, which should be plotted. Figure 12 shows an sample output of this program. The axes labels may be changed in Tree View $\rightarrow$ xaxis title, etc.

displaytext ./results/mcphas.hkl

monitors the file mcphas.hkl in a text window on screen.
