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?

You could use pladv(), which advances to the next page and clears it. This is how it is normally done in the examples. It still a bug though it seems.
