Help: adding triangle and filled-triangle to "line and point types" ???

Hi;

I appreciate all the contributers to gnuplot.  Could some guru add a triangle, and a filled triangle with an angle pointing to the left (i.e., to the set of currently available "line and point types")?  If it is not proper for public release, could I have a modified copy?  Many thanks.

 

Please note: Please kindly reply to my email address.  I am not subscribed to the list (gnuplot-info@...).  Thanks.

 

I am using gnuplot version: 4.2.3            My system:: PC, Windows XP
