How to define Y=?

[cidadao]

Hello,

This is my fist post here.

In my program I would like to make a function plot. Im using "DrawFunc <func expression>" but it doesnt store expression in Y= editor.

How can I store the expression in the Y= editor programatically?

Thanks in advance!

Here's an example:

"x^2 -> y1(x)"
"DrawFunc y1(x)"
