Dynamic graph. Sinusoidal wave. Shift left graph

Hello friends,

in this post we have a code to draw a dynamic graph:

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.

p91C_grafico_sinusoidal.aia (7.7 KB)

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.

Regards.

5.- Clock1 "fast" create point. Clock2 "slow" draw point.

Clock1.TimeInterval: 400 ("fast") create random numbers (1...1000) and AppendToFile: valores.txt
Clock2.TimerInterval: 500 ("slow"), gets the numbers from the file and draws them on a dynamic graph.
As Clock2 is slower than Clock1, a buffer of numbers pending drawing is observed.
You can enable or disable Clocks to see the effect.
Use the procedure: updateGraph
