We need jupyter tutorial for vcs syntax for writing formulas

[doutriaux1]

in 1.5.1 the follwoing used to work:

import vcs
x=vcs.init()
t=x.createtext()
t.string="E=mc!U2"
t.x=[.5]
t.y=[.5]
x.plot(t)

@doutriaux1 will confirm whether this bug exist on not.

I will send a sample VTK code to confirm VTk supports it.

@doutriaux1 @aashish24 vcs/vtk does support math text using the syntax:
"$E=mc^2$".

This is the syntax that matplotlib uses and it is a subset of latex. Is the syntax you used the legacy vcs syntax? Do we need to support that or should we switch to the much more common matplotlib/latex syntax.
Note that you can write entire formulas with this syntax.

@danlipsa true and tested a few weeks back, I want to write a jupyter notebook about it. The sad part though is that it's via matplotlib...

@doutriaux1 I'll rename this issue than, to tell us to write a jupyter tutorial ...
