A more advanced possibility is to use the scripting engine, which requires you to install Python 3.2 32 bit.

When you have Python installed you can press F11 inside Graph to get a Python interpreter and enter the following code to add the family of functions:

```
for n in range(6):
F=Graph.TStdFunc("x^%d" % n)
Graph.FunctionList.append(F)
Graph.Redraw()
```

I will consider creating an easier way to do this in a future version.

]]>can do.

Pretty important for looking at trends.

To clarify, imagine the very simple function:

y = x^n

it would be nice to ask Graph to plot this for n=0 to 5 step 1 say.

Thus a family of functions varying n.

The same applies to more complex functions indeed is where it becomes truly useful, to look at how a given coefficient alters the plot.

As it was she had to create a separate line manually for each value we wanted to look at, time consuming.
