The xGraph Class and B4XLib allows graphic analysis of signals.
It works on all three products: B4A, B4i and B4J.
The graph holds a given number of curves (10 by default) with a given number of samples (10000 by default) these values can be defined in the Designer.
All curves have the same number of samples with the same X signal.
What can be done:
- Draw up to 4 curves on the same graph.
- Show values when moving the cursor on the graph.
- Zooming, either with the cursor or setting in the code.
- Different scale modes.
- Different methods on curves.
-- Copy a curve to another location.
-- Add a value to a curve.
-- Multiply a curve by a value.
-- Add two curves and save the result in another curve.
-- Multiply two curves and save the result in another curve.
-- Calculate the integral of a curve and save the result in another curve.
-- Calculate the derivative of a curve and save the result in another curve.
