    Welcome to Physics Forums williamsk!

    I do personally have graphmatica, although I can not think of anyway to plot a Christmas tree, and I'm almost certain any relation that would draw a Christmas tree would not work in graphmatica. Sorry :( If the equation doesnt matter as much as the shape, just plot in lots and lots of points to make the tree.

    Is their anyway of drawing lines after you have plot the points

    Nope, usually when you plot some points the program can get a curve to somewhat fit the points, but a christmas tree will have lots of points on a vertical line, ie some x values will have many y values. Since this means that the curve is not a function, this severly restricts our ability to find a curve to fit the data. So basically, not :( But each point is represented by a fat circle, if you plotted enough it would look like a line.
