Sorry for this newbie question.

Assume I entered a super simple equation like:

y=2*x

Now I want to plot this graph/function in interval [-10,10]

How can I do this?

When I right-click on the equation I expected a context menu entry like "plot".
But there is no such context menu.

How else can I achieve this?

I should add a section on plotting in tutorial.

Insert> Plot> 2D

The axes control is via mouse wheel scrolling (try shift and ctrl keys) and panning

1. Shift+@ to get the plot canvas
2. enter the plot argument
3. Shift+Wheel mouse [shrink/expand X directions]
4. Ctrl+wheel mouse [shrink/expand Y directions]
5. Mouse left down to slide in either directions
6. once the initial default plot is done:
... click on plot, mouse wheel to zoom ± both directions

Ok, thank you.

However I would like to have this function available as context menu of an entered function the paper.

Could this be added in the next version?

Can you explain/exemplify ...
Do you mean: click on the plot for a drop down options menu ?

... there is a missing detail from all examples and tutorials.
The Smath 2D default plot is on the X/Y ranges ± 10.
By default as well, it plots on the canvas pixel
i.e: 96 ppi [Pixel per inch], thus the extremely fine trace,
much finer than Mathcad that plots on ½ pica [6 ppi].
If you want to set intervals otherwise: construct 2D discrete.

Egyptians had it their own ways [you know that]
For long time before the Egyptians, it is believed
the Mesopotamians had it much closer from "continued fractions".
"Pi" was approximated by various long empirical approximations [Legendre ...]
"Pi" was finally proved by Schwab [1813] => isoperimetres method.
Simon Plouffe [UQAM Montréal] method is pretty new, striking of simplicity.

The question is: can we devise some infinite numerical random suite to
approximate 'Pi' ... answer is NO ! Increase 'N' not to avail.
