[Plplot-general] plclear() does not work

[David S. <dc...@co...>]

Hello:

The plclear() method does not seem to work for either xwin or tk. As a test I modified the x09c.c 
example:

   pllab("X Coordinate", "Y Coordinate", "Streamlines of flow");
   pl_setcontlabelparam(0.006, 0.3, 0.1, 0);

   /* Plot using 1d coordinate transform */

   plclear();   // Added this line.

   plenv(-1.0, 1.0, -1.0, 1.0, 0, 0);
   plcol0(2);


And plclear did not do anything. Am I doing something wrong or is this a bug?

-- Thanks, David
