Method Detail

onDraw

public void onDraw(Canvas canvas)

Called by the UI thread to draw the timeline view

Parameters:

canvas - Reference to the Canvas drawn on

pushPath

public void pushPath(long time,
            float voltage)

Push a timeline point (x=time, y=voltage) to the path, which is then later drawn by the onDraw() function

Parameters:

time - current time of the point

voltage - current y value of the point

pushAverage
