Dynamic graph. Sinusoidal wave. Shift left graph

Hello friends,

in this post we have a code to draw a dynamic graph:
https://groups.google.com/forum/#!category-topic/mitappinventortest/general-questions-about-app-inventor-programming/fNQVDN-GPIY
142w

I used that code to display a graphic in an application with Arduino and Bluetooth.

Now I have simplified the code and show several examples:

1.- Create random numbers and draw a dynamic graph with their values.

2.- Draw the graph of a sinusoidal function.

3.- In this voltage inverter amplifier we apply an input voltage Vi = 5 mV. The Gain is -15, so its output Vo = -75 mV

4.- We can study the damped oscillator equation.
