Plot data like MATLAB or PyLab

Dear Wes,
thank you very much for your example.

So, the x part is the |jit.matrix 3 float32 1000| that is filled into
|jit.expr @expr "snorm[0]"| where the jit.noise generates the y axis
data?

I tried to adapt your example to a list of 11 floats but I must have
misunderstood a bit as I only get a single line going upwards rather
than data on the x axis.

Just one more thing I didn't understand from your patch: why is it
that when it is loaded the data is presented in the upper half of the
window, and when I press bang again the data is tilted?

Cheers

    Nik

PS, I've attached the slightly modified version where I fill up a
matrix with 11 numbers in the first plane.
