Haroon,

yes this bug has already been fixed in my working version ...

Use this in the MkLineBrush function of rrd_graph and all will be
well

  pen = gdImageColorAllocate(brush,
                             im->gdes[cosel].col.red,
                             im->gdes[cosel].col.green,
                             im->gdes[cosel].col.blue);

  gdImageColorTransparent(brush, gdImageColorAllocate(brush, 0, 0, 0));


cheers
