Format for saving files in Graph

I have a suggestion for Graph:

Currently, files are saved as .grf which can only be opened by Graph, and
Graph supports the .emf format for exporting images. My suggestion is to
combine these two formats so that a file saved by Graph can always be opened
and edited in Graph (as known from the .grf) and at the same time be opened
by image editors and inserted as images directly into other documents (as
known from the .emf). In this way, computers without Graph installed would
always be able to interpret files saved by Graph. It is my impression that
e.g. MathType works in exactly that way when saving files.

Yours sincerely,
Michael Bach Ipsen

I don't think that would be very usefull because  GRAPH  is free. And you 
always have the choice to export your plots as pictures.

I actually don't know and it probably varies. But I think one or two 
hours are normal. I don't know why it takes so long.

Sequences...

It could very usefull to add a new kind of object, the sequences wich can be 
of five kind (where u_n shoulde be read "u index n"):
      1) u_n = f(n)
      2) u_(n+1) = f(u_n)
      3) u_(n+2) = f(u_(n+1),u_n)
      4) x_n = f(n) et y_n=g(n)
      5) x_(n+1) = f(x_n,y_n) et y_(n+1)=g(x_n,y_n)

The way this objects would be drawn would be similar to statistic lines.

Best regards.

Thanks for the suggestion. I will look into it and see if I can make 
support for sequences possible. It shouldn't be too difficult to implement.

error function

Hello. Thise programm is very simple and usefull, I liked it a lot. Especially
ability to plot implicit functions. 
Is there any way to plot error function ?

Thank you

I assume you are referring to the error function encountered in 
integrating the normal distribution. You can add it as a function 
defined as:
f(x)=2/sqrt(pi) * integrate(e^(-x^2), 0, x)
