draw#

Purpose#

Graphs lines, symbols, and text using the PQG global variables. This procedure does not require actual X, Y, or Z data since its main purpose is to manually build graphs using _pline, _pmsgctl, _psym, _paxes, _parrow and other globals.

Note

This function is for the deprecated PQG graphics.

Format#

draw()#

Examples#

library pgraph;
graphset;

begwind;

// make full size window for  plot
makewind(9, 6.855, 0, 0, 0);

// make small overlapping window for text
makewind(3, 1, 3, 3, 0);

setwind(1);

   // Generate x and y
   x = seqa(.1, .1, 100);
   y = sin(x);

   // plot data in first window
   xy(x, y);

nextwind;

   _pbox = 15;
   _paxes = 0;
   _pnum = 0;
   _ptitlht = 1;
   margin(0,0,2,0);

   // add a smaller text window
   title("This is a text window.");

   // Create graph
   draw;

endwind;

Remarks#

draw() is especially useful when used in conjunction with transparent windows.
