B4J Question oscilloscope chart (moving to the left)

[peacemaker]

Hi, All

Do we have any ready lib\class of the dynamical moving chart, like oscilloscope ?
Several lines on it...

You may have a look at the xChart b4xlib.
In the demo program you have a dynamic lines example.

You may also have a look at this thread: Scope B4A(klaus) Run B4J.

@klaus, thanks for such super lib !
But where is dynamic example more exactly ?
I see 2 test projects, static charts.

In the xChart thread you have the B4XPagesChartDemo program which allows to show the different chart types.
When you click on the Dynamic lines button, you will see it.
The routine which does the job is: DrawDynamicLinePoints.
