Making nice figures

edit

Some of the graphs produced by the financial functions PORT and STOCK do this automatically. To do this with the GRAPH command you can easily edit the graph script from the 'Edit Source' button on the Graph Viewer to do this yourself - adding using the 'Edit Data' button should you need to.

Here is a simple example where we both add data, y axes labels and a second axis by hand to an existing graph.

1) Open SHAZAM 11 and then open the 'Introduction' on the Help menu.

2) Open the Dynamic VAR.gnu Graph and click 'Edit Data'

Add an additional column (column 3 below)

3) Click 'Edit Source' and adjust the graph as follows:

Before:

 # SHAZAM COMMAND:GRAPH   
 set samples  26
 set title " Dynamic Forecast from VAR(1) Model for last 25 Obs of Y        "
 set key
 set xlabel "TIME    "
 set ylabel
 plot  "Dynamic VAR_1.shd" using 1 lw 2 title "Y1    " w linespoint,\
       "Dynamic VAR_1.shd" using 2 lw 2 title "PREDY1" w linespoint  
 quit

After:

 # SHAZAM COMMAND:GRAPH   
 set samples  26
 set title " Dynamic Forecast from VAR(1) Model for last 25 Obs of Y        "
 set key
 set xlabel "TIME    "
 set ylabel "VAR"
 # ADD 2ND AXES AND PLOT CONST
 set y2label "CONST"
 set y2range [-15:100]
 set y2tics 20 nomirror tc lt 2
 plot "Dynamic VAR_1.shd" using 1 lw 2 title "Y1      "  w linespoint,\
      "Dynamic VAR_1.shd" using 2 lw 2 title "PRED_Y1  "  w linespoint,\
      "Dynamic VAR_1.shd" using 3 lw 2 title "CONST_Y2 " w linespoints axes x1y2  
 quit
